A Practical Approach To Shushing Your PC

An anonymous reader points to this wacky but effective-looking home-brewed answer to computer noise, consisting of a wooden case stuffed with ventilation shafts which follow a number of 180-degree turns, and implementing several ideas found at 12ghosts.de (in German). From the description on the site: "By traveling through the shafts, the noise is weakened gradually on its way through the sections. On the front the case has a door for accessing drives, the cables come out of a kind of "mouse hole" at the rear panel. A fan inside pulls an air flow through the wooden box."

  8. The risk of chasing the silent PC by hanssprudel · · Score: 5, Insightful

    The problem with going after the silent PC at all cost is that the level of noise is not purely objective, and there is a strong psychological aspect to how much a sound will disturb you. A lot of people have computers that sound like F15s during take-off, but seem completely surprised when you even mention the noise to them: other people start trying to silence their computers, yet end up finding even the slightest hum annoying.

    The problem here is the way our brain work in regards to sound. If a sound is percieved as a threat, then the sound amplified subcontiously, where-as ambient sounds that are percieved as mundane are muffled. It is not difficult to understand why we have evolved that way.

    When you start trying to silence your computer, it is easy to start thinking of any sound you hear as a "failure" and thus a threat, which will make you focus on it. Thus you have people who get a silent power supply, only to suddenly find themselves driven up the wall by the CPU-fan, and then the harddisk.

    The extreme end of all this, of course, is tinnitus. I've suffered from this condition for ten years, and it is like having a noisy a computer inside your head that nothing can turn off. But at the same time, it works just the same psychologically: if you start fearing the sound, running from it, thinking about how it will be there for the rest of ones life, the condition becomes unbarable. Whereas if you can tell yourself that it really isn't that bad, and learn to just accept it, you can live almost undisturbed. (The latter is easier said then done, even when you realize it is true - myself I tend to have good periods followed by bad.) Some people even argue that tinnitus is entirely psychosomatic in this sense (I would like to believe them).

    So, just as a warning, a silent PC isn't a bad thing, but be careful about how far you take yourself down the road of fighting the noise.

      You make some good points, but there's more to it than that. Computer sounds often make very good diagnostics that the ear used to ignoring "everyday" sounds can pick up on and detect problems before they're uncorrectable. The *absense* of a fan sound can trigger a "replace fan" impulse; the sudden and dangerously loud whine of a hard disk can say "you may have a few hours or you may have a few months, but back me up and replace me ASAP." Unusual modem sounds have woken me up and clued me in to system crashes, both mine and other people's.

      If you hear your computers all the time, you can detect these things. But if your computers are silenced, you may be oblivious. I consider the background sounds helpful, not annoying.

      I have suffered tinnitus in the past (and I still occasionally do) but I have found out I am able to make it go away completely using the following method:

      - Imagine a very strong sound with the same frequency as the most disturbing component of your tinnitus. Concentrate. It's hard to explain, but you must keep on trying to generate this sound yourself in your head, like if you are singing or whistling but without actually doing it.

      - After a short while (20-30 seconds) the tinnitus will disappear. It will come back after a while, but weaker. Repeat.

      - After a few iterations the frequency you focused on will have gone completely, but you will notice other, weaker frequencies in your tinnitus. Do the same thing to them.

      - Eventually you will end up with a tinnitus that is more noise like, instead of composed of pure tones. This is much more bearable, but you can still do better.

      - Try to generate the same kind of noise. The noise will not be completely white, but will have 'texture'. Imagine it (think 'sssshhh'), fight back. The noise component too will rapidly fade.

Several studies show that having computers perpetually running can cause people to become aggrivated often, due in part to the noise produced by loud fans or hard drives.

    When I had my first computer, I remember every 2-3 minutes the fan would intermittantly become about 40db louder than it should be, warranting a swift kick (or 2,3,4,..) to the side or front panels of the case (and I'm not a violent man). So I can definitely sympathize with why some people find a quiet computing environment optimal.

    Sorry, little walk through nostalgia lane. But that said, I do have a few recommendations for people that don't want to build their own wooden case just to limit noise output.

Cables thus run from the desk in the basement through a 2" x 3" hole in the paneling under the desk and into the computer. By closing the door that separates the two rooms, I simply cannot hear the computer, even during hard drive activity and full fans blasting.

    First I got the MSI FX5900 with the dual fans. Makes less noise than my GF3 TI500 and a lot less heat.(no more warm cabinet :)
    Then I swapped the standard Intel P4 cooler with a Zalman CNPS7000A-CU.
    I also installed a Thermaltake PSU that I already had, which lowered the noise compared to the noname PSU I had before.
    I exchanged the Western Digital harddrive with a Seagate Barracuda which has no rotation noise, unlike the WD harddrive. I have a 5" mounting frame for the HD that suspends the HD screws in some rubber thingys that I hope will lower the head movent noise that the Seagate does have.
    Finally my cabinet has room for a big fan in the front which I have installed and adjusted so it runs slowly with little noise.

    So what now makes the most noise in my PC are the fans on the Thermaltake PSU. Regarding the cooler. The CPU temp went to 35c when idle(and fan runnin 200rpm) and 50c under full load with fan running at 70%(before staring to make noise). With the original cooler the idle temp was 43c and it hit 55c(full fan speed and a lot of noise) under full load where the motherboard kicked in at fired up the fan to full speed. I don't have much expirence in this and I am a bit unsure if I have applied the correct amount of thermal paste, but I have a lot left for experimentation, so I will try different configurations. I was expecting poor air flow inside the cabinet to be the cause of the high operating temperature but I tried opening the cabinet and placed an office fan above it to make sure the air in the cabinet was room temp. and the CPU temp. readings was pretty much the same. They only got 2-3c higher when the cabinet are closed.
    Also if anyone has any suggestions for a silent harddrive, I would like to know. Of course I would like it to be fast but noise levels are the top priority.
    It has been fun playing with this, tryng to make the optimal air flow and getting the most out of as little cooling as possible. And it is now clear to me that noise reduction and a silent PC is often one of the things you don't get in a DIY PC unless you put some effort into it.
