Computers And The Noise They Make

Weeden writes: "Here is a Salon article that wants to know why computers have to make so much noise. They think if the iMac can be quiet, why can't everyone else?

Quiet is certainly a concern for all-day computer users; I know I'd pay quite a bit more for a nice ATX case with a massive heat sink, if that were practical. If you need quiet now (and like the Salon writer, aren't willing to switch to an iMac) you might also want to check out this Ask Slashdot on the same topic.

Re:Err, they're not really THAT noisy...

[Robert S Gormley]

I think heat would be another factor. I know my bedroom is a few degrees warmer than the rest of the house, attributable to the PCs...

Err, they're not really THAT noisy...

[DrEldarion]

A good portion of the newer computers that I have run into aren't noisy at all. In a room that has even a little bit of noise, you can't hear the computer at all. If it's totally silent, you may be able to hear the fan, or the hard drive working, but really, is it that much of a deal?

Re:Err, they're not really THAT noisy...

[Seumas]

Of course, the Mac is built to be difficult to open, so the little bits and pieces that need to exist for easy manual extraction of hardware are less frequent than in a standard PC. I think that lends itself a lot to decreasing the sound.

I'm planning on taking a lot more care in building my next PC. I usually get eager about all the cool new stuff I'm going to throw into a box and can't wait to get it up or running. The next box I build is going to have a customized case -- specifically designed for both noise reduction and cooling. I think a lot of planning for this next machine will be spent on those two items of interest, over and above the other components.

Of course, I really don't have much use for anything beyond the AMD K6-2/400mhz that I have right now (well, I haven't had it for about six months -- it's still up in Portland with my parents). I probably won't put another machine together until the 1ghz chips have become old news. I don't play many video games on my boxes and putting a massive box together just for coding, MP3s and surfing is total over-kill.

Re:Err, they're not really THAT noisy...

[Seumas]

When you're in an office where every person has three 21" monitors, a couple Ultra 10's, a couple P3/600mhz's and a laptop on their desk, you'll definitely notice just how noisey they really are.

Our division recently moved from Mountain View to Santa Clara and I stayed behind for awhile in the old office. Even with just a hand full of machines running and nobody in the office, the noise was enough to drive you nutty.

Thankfully, our new offices are real offices (not cubicles). Granted, they have goofy sliding doors instead of real solid wood doors, but at least the glass is somewhat sound-proofed. With my door closed and the lights off, I can tolerate the noise of my boxes purring along, even when I have my music turned off. But throw fifty of these things together -- or even a hundred or two hundred, in the same general and open office space and although the noise cancels itself out, it still registers in your poor head. It's a wonder people have headaches so often in these environments.

Even my dinky Dell Latitude CPi laptop drives me nuts with it's horribly clanky CD drive and hard drives.

As long as the need for mechanical moving parts continues, the noise will also remain. I don't see any inexpensive or simple ways to avoid all of these noises so long as there are plates spinning in your hard drive, CD's spinning in your CDROM, and fans cooling your system off.

Perhaps some sort of additional enclosure around the PC case -- with slots for peripherals -- will help ease the noise, but this would probably have to be a custom job. Maybe something like a big Tupper-Ware box with the same sort of sound-abosrbing tiles that you find in an office ceiling fastened about the entire inside of the secondary case -- with a couple small slits in each corner to allow for air-flow. If it's made out of the right material, you could probably avoid any aditional cooling technology to be implemented.

I don't know -- just an idea.

Noisy computers in bedrooms

[Antipop]

As computers become more and more commonplace, a lot of them are put into bedrooms. Do you know how much frickin' noise my P200 makes at night? I'd love to hit high uptimes to brag to my friends, but I can't cuz I have to shut the thing off at night! Anyone know of a cheap, easy way to reduce noise? I've heard of people placing carpet padding on the sides of their case, I'm going to try this and see if it helps.

Re:Noisy computers in bedrooms

[Anonymous Coward]

use hdparm -S to put drives to sleep after a certain amount of time.

if you use windows you can set them to go to sleep too after a certain amount of time, however, I have found in about 85% of the computers running win9x that once they go to sleep, they lock up real hard, requiring a reboot, kind of making the whole sleep thing a stupid 'feature'
Linux doesn't have the sleep->solid lockup feature yet, but its planned for 2.6

Re:Noisy computers in bedrooms

[Spyky]

I've never tried putting dynamat inside a computer, but i don't know that it will help much. I've used it extensively inside my car, mostly it deadens cheap door panels that vibrate and create noise. I don't think putting this stuff in your computer case is going to silence noisy fans and hard drives. The noise such devices create is pretty high pitched, and well outside of dynamat's optimal dampening range. Dynamat works best with in between frequencies, its fairly ineffective against low base and high treble.
In order to really cut down those high pitched sounds, you'd have to enclose the entire PC in a sealed box, but that sort of eliminates the point of fans now doesn't it :-)

If you don't need the computer at night, why not just turn it off? What does uptime do for you?

Re:Noisy computers in bedrooms

[drix]

I just took out all the fans in my case/power supply and replaced them with their equivalent "queit" version from here. They have standard 80mm fans which are way quieter. They also offer a silent power supply, but it's expensive and I have a feeling it's just a normal PS with a quiet fan stuck in it. You can do that yourself - easily. Also worth mentioning is their Silent Drive enclosure - I don't have one, but it's the mechanical whine of the hard drive that really bothers most people. The white noise of the fan is actually quite relaxing. I can't sleep in a room that doesn't have a fan going... besides, the smartest and cheapest thing to do is to just spin down your hard drive at night. It's easier on the drive.

Carpet, BTW, is a no-no. To make a long story short, save yourself a lot of trouble and do not do that. Ever notice how carpet becomes electrostatically charged easily? Ever notice how dust is attracted to carpet?

Riiight... now you get it :)

Re:Noisy computers in bedrooms

[Signal 11]

Yup. put a resistor inline with the fan. You'll need to do alittle soldering, but if you reduce the speed of the fan, you'll do miracles for noise. DO NOT use carpeting inside your case - those things attract dust and will quickly choke the life out of your fans, as well as be a fire hazard. If you must, consider using something like Dynamat, which you can pick up at any car audio place. It is what car audio enthusiasts use to dampen noise in their trunks, along the floors, etc. It's basically a thuck chunk of rubber. It'll cost you alittle bit, but it's guaranteed to dampen noise.

If you wanna get creative, make a small box outside the fan and use tissue paper or something to form a "sound barrier" around it. You'll need alot of surface area for it to suck air into, but that might help. Keep in mind that fans don't take well to decreased air pressure.. so check it before you seal it up.. or better yet - use a blower. Blowers are better at building pressure, at the expense of a slightly lower CFM rating.

Ciao!

Heat sources

[DragonHawk]

one main reason, so far as i can tell, that the imac can live without a fan is that its chip has far lower power consuption, and therefore generates much less heat that the x86 counterparts

Certainly the PowerPC helps. But I have to wonder: In my system, at least, the CPU isn't the biggest heat source. The hard drive spindle motors are. After that comes the NVidia TNT chip. (Not even a GeForce!) The CPU comes in third. Now, granted, I don't have the latest space heaters from Intel or AMD, but still, I have to wonder about these new fanless iMacs. I've seen the demo machines in stores, and I have to tell you, those suckers are hot to the touch. Can any computer running that warm really be in good health?

Re:Heat sources

[King Babar]

One important point to remember is the fact that these are demo machines, which means that people are jostling their mice and tapping their keyboards j-u-s-t enough so that the power management software doesn't get to do its thing. And then you get an iToaster.

My iMac at home is in the kitchen, and gets intense but sporadic use, so that it's asleep well over half the day. That really does help a lot.

Re:Heat sources

[mbrubeck]

I have to wonder about these new fanless iMacs. I've seen the demo machines in stores, and I have to tell you, those suckers are hot to the touch.

Much of that heat is coming off of the CRT, which is a major heat source in any machine. The heat that does come from the other componentry rises pretty quickly to the top of the case. Feel the bottom of the next demo unit you see and you'll find that it's quite cool.

I do worry a bit about my iMac 350 when it's running Linux for too long, since the new power management unit isn't supported by the kernel yet, and the builtin monitor in the slot-loading models doesn't respond to standard vesa blanking. I can spin down the harddrive to reduce heat generation, however.

(I run Debian on my iMac/350.)

Re:Heat sources

[Tower]

My 10krpm drive uses 20W max... A iPMMX 233 uses ~19W... Some of the P-II line use ~40W. Most drives don't have a fan on them, but even a small fan keeps my drive cooler than the CPU...

Re:Heat sources

[adolf]

(Score:-1, Redundant)

iMacs run hot, just as TVs run hot, monitors run hot, and most other vacuum tubes run hot. This says nothing about how warm the computer itself (which is placed below the CRT inside the box) runs. Gravity being what it is, heat rises and creates convection currents, and (in the case of an iMac) the chimney effect. Cool air comes in the bottom, warm/hot air exits the top. Just like it might if there were a fan in place, without a fan.

Incidentally, this is also a main reason why the primary cooling fan in a vertically-inclined computer exhausts air from near the top of the case, while cool air enters at the bottom (certain ATX 1.0-compliant power supplies excepted, due to stupidity on intel's part).

That all said, I'll attempt to identify some potential trouble-spots and some possible solutions for them:

The computer, as a whole. Heat reduction, damping and isolation are key (in that order).

Reduce heat by taking out everything that makes heat that you can get by without, and reduce cooling capacity accordingly.

To isolate it, move the box far away, and/or put obstacles between it and you. The Other Side of the Desk is a good option, or in a closet if permissable. The only reason you might need to fiddle with it with any frequency these days is to access the CD-ROM drive, and probably only then if you're a gamer, or you listen to audio CDs with the computer. If the latter, simply plonk out $50 (or less) on a cheap portable player and a patch cord from Radio Shack, and you'll probably enjoy superior sound at the same time. If you're a gamer, learn to deal with it, or crack your software to not require CDs to play, or invest in a multi-disc changer (which is handy, anyhow).

For damping, use Dynamat, which is an asphalt-based adhesive-backed compound which seeks to add non-resonant mass in quantities suitable for sound deadening purposes on light-guage sheet metal. Typically, it comes in a roll, sold by the square foot, and appplication is just peel-and-stick. It's a little pricey for what it is, and there are knock-off brands which probably work just as well for less money. It's important to note, however, that the adhesives used in Dynamat don't degrade with heat, and will probably stay attached until well after you're dead and buried, which is good. Buy it at your local car audio shop (don't worry, they all know what it is) or online at Crutchfield or Parts Express.

The purpose of this is to keep sound inside the computer, inside the computer, and/or kill it as it tries to leave, by making the large, expansive steel panels that comprise the cover of a computer much less prone to resonance. (Note to the more hardcore hardware hacks: This will require that you find, and replace, the top cover for your case.) Carpet pad, or wool carpet, or open-cell foam, or accoustic tiles, or anything else of that variety will not have an appeciable effect. These products all have their place, which is typically to provide a cushy surface to walk on, or a good accoustic enviroment - not sound isolation (the two are mutually exclusive). If your computer has its back to the wall, you might try placing some Sonex or Studiofoam on said wall to absorb some of the sonic reflection, but don't count on it being any tremendous benefit unless you've already done something about the sound travelling through the sides of the case.

Enclosing the case is probably not an option, though some here have suggested it. In enclosing it, you'll be eliminating your access to it. And also eliminating any external airflow. Add airflow, and you either a) create a path for internal noise to get out, or b) adding additional noise by throwing even more fans at it.

CD-ROM drives. The cheaper, the noisier (or so it seems). A LiteOn 32x ATAPI I have sounds like a jet turbine; in contrast, a 32x Plextor is more-or-less silent (but the newer 40x models seem to be louder). Solution: Buy a CD-ROM drive based on noise output, instead of data output and price. (Note that this will involve leaving the house, and possibly being social.)

Hard drives. Sure, you can put them in a Quietdrive box, which is just sorbothane (or neoprene) rubber, wrapped in open-cell foam and shoved into a plastic box with zero airflow, and they'll be quiet (and hot, dispite the marketing department's claims otherwise). In this case, however, more traditional methods may be best: Move the drives further away from your ears, and you'll hear them less. Use LVD SCSI, if needed for distance (and enjoy a performance boost, to boot). Else, you can try applying Dynamat to the surfaces that the drives mount to, trimming around all the holes. Do *not* put Dynamat or any other poor thermal conductor directly on a hard drive (even substances with "good" thermal transmission characteristics may block breather holes on the top of the drive, which is a no-no). Or, try to find a quiet hard drive. Not that this is any easy task. I used to think that IBM's 9ES series of 7200RPM drives were quiet, until I recently bought and installed a more recent revision and noticed that it was no longer the case (that installation, sadly, was in a recording studio). On the other hand, they're particularly cool-running drives, which alleviates some cooling needs. One other possibility is that Quantum (IIRC) claims to have a line of quiet IDE drives.

But, take all noise ratings with a grain or salt (or 20). They're usually expressed in terms of dBA, which is fine. However, they disclose zero details as to the measurement enviroment, distance from the measuring device, mounting to resonant surfaces (such as a computer's case), or any other factors which will have tremendous impact on such figures. If you want to get particularly anal about it, go to Radio Shack and get an SPL meter. The analog version goes on sale twice a year for something like $30. It will tell you exactly how loud something is at a given point. So, establish your a test procedure, and begin measurement. (If this seems like a silly thing to do, you're right.)

CPU fan. Personally, I don't see the big deal here, as long as you use your ears when selecting one (or trust the marketing folks). PC Power and Cooling is well known for their quiet, long-lasting, and effective fans. Alternatively, I've got a Cooler Master on a K6-2 which does the trick, making negligable noise. In contrast, a Global Win fan that lives on another K6-2 here out-whines the cheap Japanese hard drive, the LiteOn CD-ROM, Mitsumi CD-R, and ball-bearing power supply fan combined. Luckily, the DFI motherboard offers some sort of fan-control that speeds up the fan (in Windows) when there's significant CPU activity and slows down when there's not, but it still screeches like a banshee even when kicked down to low idle.

Rule of thumb seems to be that the bigger the heatsink, the higher the output of the fan which is attached to it. It doesn't need to be that way, but it is (*sigh*). In truth, the larger, or more dissipative the heatsink, the less air you need to have flowing over it. And, after you hit a certain point on size, you need no fan at all. CPUs these days can run *hot*, all day, every day, and continue to run at peak (rated) performance. You probably will need a fan if you're overclocking, but that's the price you pay.

In a normal system, the only things left are the one or two fans left on the case. If you have two of them, try disabling one. It costs nothing and doesn't hurt to try. Feel the top of the case periodically, both before and after the change, to get a rough idea of how it affects the internal temperature and plug it back in if you deem it too hot. If you need something even quieter, or require more than one fan for proper cooling, you can buy lower-output fans from Mouser Electronics, or a silent (but fan-cooled) power supply from PC Power and Cooling.

Re:Heat sources

[jafac]

The fact that the case feels hot is a GOOD thing. It's doing it's job and dissipating heat. If it were NOT hot, that would mean that the heat is trapped inside.

Just like, you can tell, the well-insulated homes are the ones that have tons of snow on the roof. The ones leaking heat melt the snow.

If it ain't broke, fix it 'til it is!

Definitely...

[N8Magic]

If someone were to design a cost effective version of a iMac heatsink/case that actually had room for expandability, i'm sure it would catch on. Thing is though, we could get away with having just a CPU heatsink, but it is all the other peripherals that are also generating a lot of heat. Not saying that everyone has one, but those 10,000 RPM drives generate a _LOT_ of heat. Hell, even my 7200 rpm drive gets hot. My graphics card, PS, even my chipset controller gets hot! There is simply no way to cheaply build a case that could effectively take heat away fast enough that wouldn't weigh 100 lbs, or be about 4 feet by 4 feet, by 4 feet. My $.02

Re:Err... they get noiser as they get older

[cute-boy]

fans in PCs are cheap componants with crap bearings. therefore cheap fan = better profits. also the blades and housing collect dust so the air flow is less smooth.

and it always makes your new PC seem so nice for a while. if PCs didn't rattle and wheeze as they got older poeple would have a reason less to upgrade.

on a similar vein, why do old PCs always look discoloured. perhaps the dyes on the beige are designed to turn to that special nictine-stain colour...

Re:Hmmm....

[Joe Rumsey]

I'd like to know what these people are using that is so loud. Maybe they just don't remember what stuff USED to sound like.

I remember my Apple ][ didn't have any fans at all, so except for the floppy drives was completely silent. That's what stuff used to sound like. Total silence except when reading a disk. That goes for all those 8-bit computers, they just didn't need fans unless you added a whole bunch of extra stuff inside the case.

I have one P200 that's several years old and is pretty darn quiet. Good case, good fan (yeah, only one fan, imagine that!). Everything else I use is loud. Mostly only loud enough to be annoying when I stop to think about, like when someone posts a story about it to slashdot. But nevertheless, loud.

Reusing old solutions from the past

[bee]

If I could find one, I'd get one of those big foam-lined enclosures they used to make 15-20 years ago for putting printers in, back when laser printing hadn't been heard of and printers were these horribly noisy contraptions generally coming in two kinds: dot-matrix or daisy-wheel, both of which involved mechanical bits striking a carbon ribbon to deposit the ink onto the printed page. Enclosures were virtually manditory for any printer that got even moderate use that was in an area that people were expected to stay in. They'd hack off a good 30-40 decibels off the sound level, taking even the noisiest of printers down in volume to something you wouldn't mind standing next to for a couple of minutes while waiting for your printout to come out.

I would expect that probably 3 or even 4 systems could fit into an old printer enclosure; the biggest problem would probably be airflow. The slots for paper coming in and going out would probably work as long as they were positioned properly. Some experimentation definitely would be in order.

I HATE MY NOISE

[jcoiner]

Music played on decent hifi gear sounds Good. And it really sounds a lot better if you can get rid of the fscking computer noise... Everybody here is like, "I just turn up the music if the noise bothers me." This isn't too bad for a lot of pop music that has practically no dynamic range. But for anything with quiet passages or subtle details, the noise obscures it.

I've been battling this issue for a while. I tried making a computer with no moving parts... It booted linux nfs-root, no power supply fan, open case for ventilation. I couldn't get the cpu (a k6-2-380) to run at full load with the largest passive heatsink I could find w/o getting too hot. Underclocking didn't help much. Running it at like 5% CPU load, it was cool, and silent. If you put your ear real close to the mobo you could just hear the cpu voltage regulator switching. That ruled for noise, but it was a scrude up setup, not really suitable for day to day use. I got sick of plugging and unplugging the fan a lot.

I settled on a normal box with normal fans, and put it in the closet and got some extension cords. This worked just as well. If you're going to try this, make SURE you get a "high resolution" video extension cable, with the RGB signals carried on 75-ohm coax conductors within the cable. This results in practically no signal degradation, as opposed to cheap video cables that turn the image into sh!t. Saving those few dollars is not worth it.

The university just relocated me for the summer, goodbye closet. A friend of mine gave me some carpet mat... guess I'll try that soon. (thanks laura)

Good luck to everybody who wants a quiet/silent machine.

Re:I HATE MY NOISE

[Admiral Burrito]

I couldn't get the cpu (a k6-2-380) to run at full load with the largest passive heatsink I could find w/o getting too hot. Underclocking didn't help much.

Try underclocking and undervolting.

Undervolting makes the biggest difference- according to some article I read somewhere heat production is linear to the clock frequency, but exponential to the voltage.

You usually need to underclock in order to undervolt. As I understand it, at lower voltages the transistors take longer to change state, so they may not be able to keep up with the normal MHz.

Re:My silent system

[Spoing]

That's not a bad idea at all.

Actually, adding more fans, but running them at a slower speed using resistors, would cut the noise and not cost too much more per machine.

It sure beats going to a high-priced ultra quiet power supply and expensive ($25+) fans.

Re:People are just whiney...

[DJerman]

Tinnitus sufferrers can find their computer use is limited by their ability to stand the hum. Tinnitus is "ringing in the ears", usually caused by trauma or as a side-effect of an ear infection. Lack of variation in the soundscape (like silence or white noise) frequently causes the ringing to increase in volume, often becoming intrusive or painful.

So for many, this becomes a serious ergonomic issue, and a handicapping situation. Not "whining".

Thanks to the person posting about QuietPC.com. I notice they have a PIII passive cooler. Anyone know of one for Socket7?

I made a CD to demonstrate this, which consisted of sound clips that were from cd, sound clips that were mp3'd then decoded to cd, vinyl that went straight to cd, and vinyl that went from the ADC to an mp3 encoder then to cd. If you spent any money on your audio equipment at all, you can hear.

Re:Good idea, but be careful

[dragonfly_blue]

Thanks for the advice, I just took a wild stab at the mod; it's my box, so although I won't be thrilled if it starts to bug out, I won't be especially heartbroken either. ;-)

It seems to be working fine so far; $ uptime 12:10AM up 2 days, 13:06, 1 user, load averages: 0.08, 0.08, 0.08 $ and it would be longer except I upgraded to OpenBSD 2.7 when it came out last Thursday. If the fan/PS are still running, can I assume that the resistor/fan mod is working OK? Or is it dangerous to run for extended periods of time?

What kind of resistor would work best for a resistor in series here, for a 12V fan? I know you probably can't tell me exactly, but a ballpark range (watts/ohms) would probably help me (and others) out. Are there any good practical sites you know of that have very simple electronics lessons? I'd love to learn more about this stuff, it always interested me.

In terms of air flow, it seems to be getting enough flow out the back of the case; the temperature of the air is cool, so if it was overheating I'd probably be able to tell by now.

Reminds me of the William Gibson quote...

[Croaker]

This all reminds me of a William Gibson interview I read once, where he talked about his illusions about computers being shattered by noise:

...Then I went out and bought an Apple II on sale, took it home, set it up, and it started making this horrible sound like a farting toaster every time the drive would go on. When I called the store up and asked what was making this noise, they said, "Oh, that's just the drive mechanism--there's this little thing that's spinning around in there." Here I'd been expecting some exotic crystaline thing, a cyberspace deck or something, and what I'd gotten was something with this tiny piece of a Victorian engine in it, like an old record player (and a scratchy record player at that!). That noise took away some of the mystique for me, made it less sexy for me. My ignorance had allowed me to romanticize it.

(the full interview is here).

It's funny to think back to this... computers as exotic, crystalline machines. I think everyone's jaded about them these days.

I was thinking, though, that aside from the drive, the Apple ]['s were also silent, since they didn't need cooling fans (in fact, most of small personal computers of the early 80's, such as the C64, didn't need them either).

I do remember that the first computer I used that did have a fan (an Osborne Executive CP/M machine) really impressed me by sounding... well... Powerful. It made this sort of turbine-whining noise as it started. It made a breathy white noise hiss while it ran, which reminded me of huge computer rooms packed with Serious Equipment. Last time I stuck my head into the server room at work... wow... that was really noisy.

Ah well. I'd love to have a silent PC again. I'm planning on using my old Pentium Pro 200 as a server PC, but I'll have to suff it someplace in my apartment where it's out of the way. The fan isn't bad, but the drives whine like a bitch.

Ah, for the good old (fanless) days of computing...

Re:Hrmm

[wik]

Similarly, DECstation 5000's have three fans in the case, but they run extremely quietly. They are positioned to blow air across the entire motherboard. Granted, these are diskless boxes and the 10-year-old full-height SCSI drives make quite a racket, but the machine itself is pretty quiet.

Storing things in the other room, particularly with a keyboard/mouse/video extender is an expensive (for decent components) solution, but it works well.

My noise is my pet.

[Grendel Drago]

I, for one, had trouble sleeping in my room the night before I went off to college. Then it hit me -- my box was shut down, leaving only the eerie quiet of creaking rafters and settling house. When I go to a new place, I can't sleep unless I put on a fan, which itself is a poor substitute for the distinctive case-muffled hum of my baby.

If it were silent, I'd be in serious trouble. Serious -- I become nervous and scared in complete silence. (I'm not a freak!)

You mean everybody doesn't hear that? I figured i must be at least a little over-sensative, since i can hear a medium size TV through a closed window from outside, but i'd always just assumed everyone heard that annoying buzz and just ignored it..

Rebel NetWinder...

[suwalski]

I use a Rebel.Com NetWinder. They're sooooooooo quiet. Half the time, the fan's turned off! No heat!

But when I have to use a PC, I stick to my old P233 with a fairly quiet power supply fan, one fan at the front that I may as well take out, and one on the CPU. None of this PIII monstrosity with like 5 fans on it!

Well, I guess I'll have to upgrade soon... =(

Hmmm....

[TheReverand]

I'd like to know what these people are using that is so loud. Maybe they just don't remember what stuff USED to sound like.

Case in point, I have an old x86 box running SCO. It has 3 Full Height SCSI-2 5.25 drives. These mothers are DAMN loud. I'm talking a high pitch whine that attracts animals from miles around (and drives my cat up the wall).

Next to it I have another more *ahem* recent machine. It's a 550 with CD/RW, CD, 2 IDE and 1 SCSI-3 drive. Full Tower extra wide Server case I ganked from a client, with 5(!!!) fans. I can't hear the fans over the TV. Why? The case.

The case is made out of steel. I am not going to pretend to understand why, but this is the quietest case I have ever owned, (the heaviest too).

My point? I think with these super cheap, tiny cases you are going to have more of a noise factor. The cases are all plastic and have 0 insulation. Let's face it, most of these companies are using sub-par parts in order to keep their costs down. CHeap fans are loud, Cheap HD's are loud, and cheap cases let all the sound out.

Marc

Of course let's not forget the sound of MS users screaming at BSOD's. They probably make the most noise of all. `;^)

Musicians...

[clifyt]

The prob I have with noise is that I do quite a bit of accoustic recording. I swear to gawd that every damn recording I have naturally has computer fan noise in the background. Noise reduction software does little to fix these as thay all have artifacting associated with them (not that those that think MP3s are CD quality would ever notice though). My Powerbook makes no noise, but I can't hook up my Darla to it. iMacs are great, but they can't accept PCI card.

A fanless computer would do a lot to solve my probs. Right now, I just hook up long wires (actually a KVM remote) and run the CPU outside of the pianer room where it don't make no noise.

Re:x86 vs ppc

[Frymaster]

Here's the deal: The G3 uses very little power, as has been stated, however that only accounts for the removal of the cpu fan. You'll notice that the Yosemite towers have case fans.

The reason the iMac has no case fan is its "chimney" design. The fanless-computer has been an Apple design mainstay since '84 and was one of the reasons why the original Mac was vertical in design instead of horizontal like all other computers of the time. By building a very vertical box with a horizontal component layout, heat can "chimney" up and out. It's the same theory with the iMac.

On a related note, another reason why I find my Mac far quieter than my x86 beast is the CD drive. Anything above 24x sounds like an F-18 in heat. Apple made the decision that the marginal useful gain a 40x (or faster) CD offers is not worth the the atrocious noise. I bought Caesar III for the Winders machine, and mothballed it after an hour. It accesses the CD so much I found it worthwhile to pay for it again when the Mac version came out.

x86 vs ppc

[T.Hobbes]

one main reason, so far as i can tell, that the imac can live without a fan is that its chip has far lower power consuption, and therefore generates much less heat that the x86 counterparts, and therefore require less cooling

Re:x86 vs ppc

[gad_zuki!]

The article answers this question, the analog part of the machine (monitors speakers) are isolated from the digital parts. Heat from the monitor rises up away from the chip/MB and the chip is cooled through traditional Apple vent design.

BTW, there's no PC noise when wearing headphones. Sure beats $80 in cables to hide your PC in the closet.

Re:Quieter Cases

[hey!]

How effective is the case? Try pulling open the cover that hides the CDROM, and notice the difference. The machine goes from just about inaudible to definitly there, but still quiet.

Not to mention that the case opens like a door to access the innards of the box. A lot of folks like me tend to run computers with the cover off because it is usually made of flimsy, flexable sheet metal that has to be bent to just the right degree to fit in a tiny groove in the chassis. The Apple case gives regular computer users the kind of convenience that you usually see in server class machines.

Alternatives exist, even for Wintel

[BobandMax]

I build all my boxes with PC Power & Cooling components.

http://www.pcpowercooling.com/

Not only are they better cases, power supplies and fans, but they are VERY quiet. Keep in mind that I only use the "Silencer" series and have not tried the "Economy" or "Performance" components. Their stuff is a little pricey, but well worth it. I have a P133, Dual P-Pro 200 and a 600 P3 in a 10' X 10' room with no carpeting. Think I care about noise?

"Computers are useless. They can only give you answers."

Where the heat was

[DragonHawk]

This says nothing about how warm the computer itself...

Well, I felt the bottom of the sides of the iMac box, too, and that was pretty darn warm. Not as hot as the top, but still much warmer then I like. Now, I didn't pull the thing apart and stick a temperature probe on the CPU -- I think the salesmen might have had something to say about that -- but if the exposed sides were that warm, what were the components inside like?

Remember, folks, a computer running hot isn't necessarily going to burn up. High temperatures may cause erratic behavior, or simply shorten the life of your components.

Remember, also, that your average home user is going to have papers, dust, and other junk piled around the unit. I'd say the number one cause of failed components in home computers these days was heat stress, due to clogged or covered vents, or a failed fan in a single-fan system.

IMO, home computers need all the cooling help they can get. With a temperature monitor, the fan will only run when it needs to, so I really think Apple made a bad move here.

I LIKE MY NOISE

[Signal 11]

It's an important thing for geeks - how much fanage your system has. You know - it's like "normal" guys make huge garages and are measured by their piston count. Computer geeks, OTOH, are measured by how many fans and computers you have. If the lights don't dim when you power your baby up, you ain't worthy!

I got 2 120VAC exhaust fans, 3 HDD cooler fans, 3 more for the CPU, another for the GeForce, two intake fans at the base, a blower in one of the free expansion slots (two extra USB ports? who needs 'em!).. and that's just my workstation! Hell, my parents put me in the basement because it actually caused the walls to VIBRATE when I turned this beast on! Plus, I got two more fans on the switch.. another 5 inside the server box, 3 for the dev box, well.. 5 if you count the "minifans" I hung on the side, and I have CENTRAL AIR to my bedroom - yeah, that's right - when we were building this thing, I asked for 3 ducts into my room.. and shit, it still ain't enough! I'm wanting to get one of those RAID towers and some rackmount gear in here too.. I live up in minnesota and these dual-pentiums keep me nice and toasty down here...

Mmmm... more power... must cause brownout...

Dot-Matrix Solutions

[Seumas]

Run the distributed.net RC5 client on your machine, pipe the updates to the printer (it must be an old clunky dot-matrix) and then you've got yourself a nice little white-noise generator -- equivalent to using electronic devices that play sounds of the forest or rain to sooth you to sleep in noisey apartment complexes.

Trust me, with a dot-matrix continually printing through the day, the last thing you'll be concerned with is the noice of your computer fans and drives!

Everybody make some noise now... eeeh oooh

[roman_mir]

I am sitting at home by my king size ATX without the left panel on it (I keep my case open at all times) there are 3 fans on the SCSI IBM 9ZX drive (it needs extra cooling at 10020RPM). The 3dfx Voodoo Banchee has a fan on it. There is a fan on the 400PII, it's overclocked to 450 so there are 2 extra fans around it. There are also 2 other fans just for the heck of it blowing one at U2W SCSI card and one at 3Com NIC. I do not have to mention the fan in the ATX power supply. Well, basically when this thing boots up, at the point when the SCSI boot sequence kicks in, it sounds like a helicopter, but that is how I know everything is OK. You know when your car does some strange noises, you can feel something is wrong, same idea here. Otherwise this would be a v3ry silent machine.

On the other hand in my office, we have air conditioner that sounds like a turbine and over 60 computers all in the open space adding up to a good working bee hive, plus all the people who talk, laugh, use phones, move things around and even play music (not loud, mostly on their head sets).
The only way to attack noise there is to use headphones and some techno stuff. However I tried looking for an Active Noise Reduction (n0t to be mixed with Active Nose Reduction) and I found out quite a lot about these things. Unfortunately they only implement real ANS in helicopters and airplane pilot cabins. In order to get ANS at the work place you could not just put a couple of units around to make everything go silent, you'd have to use these: http://www.anr-headsets.com/ Anyway, does anyone know about implementing real ANS at a work place (open concept), I would greately appreciate help.

Top quality at a low cost

[rve]

I deliberately selected an obsolete model of a name brand PC (Siemens), to get quality rather than raw computing power this time, at a price I could afford.

So now I have a Celeron 300A based PC that turns out to be 100% reliable, and makes no noise. There is no processor fan; the only thing I hear is the HDD. Rather than be tempted by sexy clock cycles like with my last PC, I concluded that when a PC frustrates me by making me wait, it is nearly always loading something from disk, and rarely because the CPU is 100% busy, so I replaced the HDD with a 7200 rpm one.

Now if only I could find a silent PC keyboard. My neighbours complain they can hear the keys clicking if I leave my window open.

Black electricians tape

Nice and opaque. put it over the lights. No more blinding LEDs. Doesn't match the case color? Black spraypaint :) or get some of the colored electricians tape. Just as opaque.

Re:People are just whiney...

[DJerman]

You can put on an MP3 to avoid silence, but a 42 dBa whine means you have to play the MP3 TOO LOUD to drown it out.

Re:People are just whiney...

[vsync64]

So how does making the computer silent help, if it causes the ringing to increase in volume? The computer's either going to produce silence or white noise, if both of those are a problem, what difference does it make?

Why don't they just put on an MP3 or something?

Silent computers? Are you kidding? That's a pretty horrible idea. Seriously, I like a little bit of noise from my computer, just enough so that I know it's on and working. Especially the hard drive. You type in a command and enter. The computer goes to a blank screen and sits there. Is it thinking? Blocking? Stalling? Dead?

Maybe I'm just nostalgic for my old Apple IIe. Man, when it wanted to read a disk, and it didn't like what was in its drive, it *told* you about it.

Have you guys had ringing ears or loose hearing?

[antdude]

I was in a server room with loud computer fans. Geez, I can't imagine being in there for a long period of time. My ears started to rang like heck after 30 minutes! I wonder how many server operators actually go deaf? I can picture them wearing those headsets you see at the airports :).

Install a resistor at power supply fan

[OnyxMedia]

I just installed a variable resistor (POT) on my power supply fan. Now I have a little knob on back of case which I can use to turn down the noise. With the fan spinning slow, it still moves enough air volume to keep the power supply from baking, but its nice and quiet.

I used a 10k ohms potentionmeter from Radio Shack, but that seems to be way to much resistance. Probably a couple hundred k ohms would be perfect. Or you can buy a bunch of resistors and just install the one that gives you a good speed. But with the POT, on hot days, or when I won't be around, I can still crank the fan up all the way.

Noisy is right!

[gad_zuki!]

How about that POST beep? Hey dummy I pushed the button I know you're powering up.

That sound the computer makes only when I type. If I ever find the source of those annoying clicks I'm calling tech support.

That fan on the back, when will PC manufacturers make a machine for my ultra senstive bat ears? We must think of some PC catchphrase for this, Autonomous Audible Attack Syndrome anyone? "I'd love to see Stereolab tonight but my AAS is acting up."

The sounds web pages make. Why would I want to hear some Don Henley song, let alone in crappy MIDI synth form.

Removing Fans From Desktops and Machines.

[billstewart]

I used to use a diskless Sun ELC as my desktop machine - it was silent except when I had the CD running, and didn't waste much space. It was Black&White, so I occasionally needed to go to the lab to use a color screen, and it honked out when somebody did disk backups across the LAN, but it was usually just great, and 1153x900 still beats most PCs I use.

Back when we used dumb terminals, they usually came with fans. But they were usually from Hewlett Packard, and therefore overengineered and highly reliable. My boss would simply disconnect the fan in his machine - the top of the case eventually got a bit warped, but it still worked just fine, and he could reconnect it if he ever needed to get it repaired.

My friend Hugh had his computers in a kitchen cabinet, with cables running out the back to his desk in the living room, with three big monitors, keyboards, etc., but all the noisy stuff was stashed away.

New machines _are_ quieter, here's why..

[knghtbrd]

Most newer off-the-shelf computers do not have a CPU fan. My Dell PIII doesn't have a single fan on that chip and you'd think it roasts to death. No way, it's cooler than the P200 sitting next to it that can be heard from the other room. If I shut dow that machine I can barely hear a whisper. So how do the new machines keep from baking themselves? Did Intel stop making ovens instead of CPUs? Certainly not. Intel chips can still get hot enough to fry an egg without proper cooling..! Maybe it's part of their patent or something, eh?

No, the reason is that the little fan that is stuck to the top of that P200 makes a lot of noise. The one in the power supply isn't exactly silent, but compared to the one on the CPU you'd never notice.

What this Dell and a lot of these quiet machines are doing is moving the fan off the CPU and putting it in the back of the case. If you just put a suitable heatsink on the CPU itself with some heat putty and snap a little plastic baffel over the CPU, what happens is that the bigger, higher powered, quieter fan in the back of the case pulls air in side the case under this baffel, over the heatsink, and immediately out the back of the case. This is an extremely efficient design.

The P200 sitting next to it pulls the air already over the heatsink off of it which supposedly adds to the circulation (though in my experience not very much) and pushes it into the middle of the case. Usually airflow is blocked by cables or something, so there's no real unobstructed path for the air to follow. Result? My P200 is quite warm to the touch. My PIII isn't cold to the touch (it's hot in here), but it's not noticably any warmer than the surrounding air temperature. Of course, add a petlier effect plate to that heatshink and watch the temperature of that chip drop below the room temperature.

So I guess the question is, are there any good recommendations for comodity cases with a similar duct design? This plastic Dell case works, but it's not expandable enough for a real geek. Not enough drive bays and the whole thing is plastic and not nearly as sturdy as the average $80 metal case, to say nothing of the nifty CalPC steel cases we all drool over.. =)

subconscious filtering

[blaine]

The noise of computers has never bothered me. Right now, the room I sleep in has a Dual PII-450 that has a total of 11 fans in it, a Dual PPro-200 that has 5, and a PII-450 with 6. Unless I consciously think about it, I don't hear the sound.

I guess I just sorta filter it out without even thinking about it. I'm not sure how common this is though. I've been doing it all my life, sometimes in bad ways :) I remember when I was young, my mother was convinced I had 'selective hearing', where I would filter out things I didn't want to hear without even realizing it. So if she was upstairs and called down to me 'you have a phone call' , I'd hear it, but if she called down 'come up and clean your room', I would honestly not recall ever hearing it.

Weird I guess. Either way, computer noise doesn't bother me, because I just don't hear it unless I try to.

RFI leaks

[knghtbrd]

With a bunch of open systems, you run the very high chance that you're going to be leaking RFI all over the place. Plus a good cooling system (better than I have here) can cause the machine to run a few degrees cooler than the surrounding room. This is always a good thing. Your cooling solution guarantees that the machine's components will be at the same temperature as the room they're in, if not perhaps a little hotter due to energy/heat transfer and lack of air circulation.

Quieter Cases

[oh shoot]

There are two things that make the Apple machines quiet: Efficiency and quality cases.

The iMac is silent because it has no fan. The CPU daintily sips power, whereas an Athlon or P3 guzzles it. This leads to very little heat, and thus eliminates several things: noisy CPU fans, case fans, and noisy power supplies.

The quality plastic cases on the iMac, G3, and G4 also do a fair amount of silencing noise. These cases are made of thick plastic that absorbs noise from fans and hard drives. One of the more frustrating things about my G3 is that it lacks not only drive lights (helpful when seeing if the machine is frozen), but also the sounds the hard drive makes.

How effective is the case? Try pulling open the cover that hides the CDROM, and notice the difference. The machine goes from just about inaudible to definitly there, but still quiet.

Compare this to a PC with a cheapo metal case that has a plastic front. Every sound is clear - you don't need drive lights, because the HD makes different noises for reads and writes.

The funny thing about quiet computers is that generally, you end paying more to get less (noise, of course).

Re:Quieter Cases

[kurdraw]

I actually have one of the newer iMac DV's that does not have a fan at all, and another reason they can go fanless is the design of the case. The case is designed so that when it rests on your desk it tilts up a little to allow access to airholes for ventilation underneath, and on the top of the machine it has more airholes. This allows it do ventilate better in a "natural" fashion than most PC's do.

However, it still does make some noise. In particular you can here the HD, and if you put in a CDROM, that also makes a lot of noise.

Speed (and thus cooling) costs...

[Spoing]

I'm not talking about the costs of wasted power from hot CPUs, multiple 7200rpm drives, and 3D video cards...but the fans to cool them. In a new machinee, I have 5 fans costing a minimum of $30...and these are the cheap ones not the good quality (and quiet) PC-Power and Cooling equipment.

To cut the sound some, it would easily double or tripple the costs.

Hrmm

[mindstrm]

My sun4 has a fan in it.. but it's so quiet, you have to get your ear near it to hear at all. It's just there to provide minimal airflow.

Many computers are actually not noisy..
Peoples lust for the next fastests best thing means more heat, which means more fans....

The other thing, of course, is having all noisemaking equipment (main cpu, motherboard, drives) all in a closet or other room even, and simply have the rest neworked over some kidn of high speed bus.

My silent system

[dragonfly_blue]

I just built a server last week, and one of my goals was to make it somehow quieter than it had been. It was built from an old Compaq Deskpro a client had given up on, and when I got it, it sounded like a fricking airport. I record music with my computer, so keeping the volume level down has assumed some importance, especially since I have three or four computers going sometimes. Microphones are pretty sensitive these days, and digital recordings only serve to expose any extraneous noise in the environment, while analog tapes sometimes help to mask such artifacts.

Anyway, moving right along. I basically had taken the Compaq Deskpro apart, stripping it for parts, even took out the processor and the hard drives and cables, even the proprietary BIOS (which I subsequently had to hunt up of course.)

I had pretty much stripped the thing, short of taking out the motherboard, and chucked it in my basement for around 8 months until I remembered it.

When I rebuilt it, it took a while to find all the pieces, but I finally got it back together. Everything worked fine; I noticed it was a P-133 (not MMX) with a fairly decent heatsink on it. What the hell could be making that much noise??? It sounded like a wheezing tuberculosis patient.

So I snooped around a bit, and looked at it from a few angles, and lo and behold, it was of course the power supply fan. "Aha!" I thought to myself. "I'll just replace the fan with another, quieter fan!"

So after trying about four equally noisy fans (and lord only knows why they sounded like jet airplanes) it occurred to me that perhaps they were receiving too much current.

I'm no electronics expert, but I seemed to remember something about resistors (those funky little striped electronic thingers) resisting current, so I hunted up my box of spare parts, and tried throwing a couple of 'em on in series with the power supply fan.

Eventually I found one that was just right, and it slowed the fan down to that perfect balance, between putting out enough air current, and sounding like the Los Alamos Wind Turbine Hurricane Emulator.

I guess what I'm saying is; if you have an especially loud fan in your computer, why not just step the current down a little bit? Sure, it might not blow out quite as much air as it did, but you won't find yourself trying to figure out where that whooshing sound is coming from, either.

Probably won't work if your machine is overclocked though... ;-) In that case, get a Peltier instead. Or earplugs.

The Apple ][ Design

[www.sorehands.com]

The Apple ][ design was to eliminate the fan as to avoid the noise.

The Ergo Brick was designed without a fan. It used a heat conductive gel that used the metal case to conduct away the heat.

But if we eliminate the noise from the fan, then the noise from the monitor, the drives would then become an issue. What's the point?

Re:noisy my ass...

[Linux Freak]

Exactly. When one lives in the seedier parts of town, one finds the soothing hum of several computers a sleeping aid as it drowns out the yells of drunks and the "POP" of drive-by shootings. :-)

(Well, that was before I moved to Japan, anyway...now I sleep to the soothing sounds of ferrel cats fighting and making out in the neighborhood.)

Will ACPI help?

[Booker]

Can ACPI be used to monitor temperatures, and turn fans on/off accordingly? It seems like ACPI implementations are still pretty weak. I think the fans go off in various sleep states, but it'd be nice to toggle them based on temperature.

I don't care

I live in Houston. The A/C in my appartment drowns out almost any other noise. Hell, to watch TV I have to punch up the volume on my stereo to retarded levels just to to hear it over the A/C fan.

[Rilke]

I've solved the sound problem on the one machine in my apartment that never goes off. I disconnected the power supply fan.

Yep. It wasn't intentional, originally, the fan broke and I just never got around to replacing it. But now I've had this K7 running almost continuously (i.e., 24/7) for two years without a problem, without a fan, and with virtually no sound.

Sure, I expect the CPU to blow out at some point, or maybe lose some memory, but at this point the whole thing's been pretty cost-effective.

I complained that the noise was going to be a problem, they told me to just ignore it, and it would go away. You know something, they were RIGHT.

Gawd I sure do miss the sound of that Prime machine's power supply, the air-conditioner (that kept the room a chilly 65F, year round) noise, the numerous servers, and the Genicom 3820 and 4440 line printers!

And they are complaining about a "noisy" PC?
