Quieting Your G5?

metajunkie wants to take a bite out of this issue: "I recently set up an at-home recording studio with a DP G5 and a ProTools mBox. Problem is, I can't record (like, say, a voice over) anywhere near the computer because when the cooling fans kick in, it comes in way too loud over the mic. I can't move the computer into another room, and while I'm tempted to throw a blanket over the thing, I don't think that'll help. Does anyone know a place that sells a silencer box for the G5 or some good DIY way to cut out the noise?"

      I was going to use the last of my mod points on some other posts in this story that gave some really good tips. At least until I saw this post.

      Nothing personal, because I'm sure your comments were made with the best of intentions, and in the PC/non-G5 computing world they'd be great suggestions. However, I would not do any of the "standard tricks" with a G5. Here's why:

      Apple has done a serious amount of engineering with the cooling in the G5s. Nine fans, 21 temperature sensors and four "thermal zones". Not to mention those gigantor heatsinks. Replacing their fans, or going so far as to run them at different voltages (and thus speeds), may well cause the opposite effect you're looking for. Mac OS X may end up running the fans much more often to keep the ambient case temperature in the zones you've "played with" at their target temperature(s).

      You can get a brief overview of their cooling design here: http://www.apple.com/powermac/design.html

      Are you still in the original warranty, or did you add AppleCare? If either of those is true, you may not want to start mucking around with the cooling system components. If I were you, I'd check the warranty/AppleCare legalese very closely first to make sure that you're not voiding those agreements -- especially if you end up damaging your system.

      Here's what I would suggest instead:

      - Close all unnecessary background programs (fewer programs == less CPU usage == less waste heat == less fan noise) when you are recording your voice overs.

      - The type of recording discussed in the parent article won't need remotely near the power of the G5. Because of this, it may also help to go into the Energy Saver system preference panel and switch to the "reduced performance" power profile. This should reduce the need for the fans. When you're done recording, switch back to Automatic or Highest.

      - Keep discs out of your superdrive when recording. That drive, when it has a disc in there spinning around, can be loud.

      - Get a good directional mic and don't have your G5 tower in front of the mic, where you'll be sitting to do the recording.

      Having said all that, you may have something else going on that's causing the noise in your machine. I vaguely recall something about a batch of power supplies in earlier G5s that (I think) Apple will replace under warranty/AppleCare because of excess noise/hum. Maybe you could look into that, as well.

      And just to put all my comments in more context, I also have a G5 (dual 2GHz), an Mbox and have used ProTools for voice overs. My G5 is dead silent, and always has been. When I'm sitting at my desk, I literally hear more fan noise from other people's machines down the hallway than I have ever heard from something inside my office, including my G5.

      I can't recall, since getting my G5 last October, ever hearing the fans kick into a high speed (and this includes the times I've had FCP4, ProTools, Cinema4D, DVD Studio Pro, Photoshop and LiveType all running at once).

      Right. But fans on Apple machines have three (visibly) identical black electrical wires.

      Fan speed on Apple machines are controlled by Apple. There is no way to choose "Two fans at 1/2 speed" instead of "one fan at full speed".

      Also, Apple has a huge amount of case fans in the G5. They are supposed to run at very low RPM. I believe they have already made the decision to go with "two fans at 1/2 speed":
      To that end, the Power Mac G5's anodized aluminum alloy enclosure is designed around four independently controlled thermal zones for intelligently channeled airflow. To make the Power Mac G5 even cooler, a see-through internal air deflector channels airflow over the processor heat sinks and the expansion slots.

      Each of the four thermal zones is equipped with its own dedicated, low-speed fans. Apple engineered seven of the nine fans to spin at very low speeds for minimum acoustic output. Using 21 different sensors, Mac OS X constantly monitors component temperatures in each zone, dynamically adjusting individual fan speeds to the appropriate levels for the quietest possible operation. As a result, the Power Mac G5 runs two times quieter than the previous Power Mac G4 enclosure.
      I realize that's marketing speak, but unless a whole bunch of new stuff has come out about Apple's heat management on G5s, we still need to treat it like a black box. Do you read me now?

      I always find new reasons to be impressed with Apple's engineering. Unmarked wires shouldn't be a problem. A little harmless experimentation with the wires on the fans will determine the power, ground, and monitoring wires. Panasonic does make panaflos with fan speed monitoring, though they tend to run quite expensive. It would be very important to know whether or not the G5 can run without monitoring, but that is also a test for experimentation. If so, you can always set your variables yourself, and just feed back the RPM settings to keep the mobo chugging along yourself. Bypassing the system is only dangerous if you let parts overheat. Plus, the effects of fan noise are reduced if all of the fans are spinning at the same speeds... giving off the same white noise, if you will. Generally, the dual ball-bearing stuff that passes for low volume fans can't touch a hydro bearing one, but we can give Apple the benefit of the doubt. Assuming Apple has a great setup and assuming they have optimized fan usage for silence (which it doesn't seem like, seeing as how people seem to be complaining that it is the loudest component), there is still the option of replacing the faster running fans with a liquid cooled system and a large radiator. Such a thing could be used only on certain locations such as the CPU, PSU, and graphics card, and could significantly reduce overall volume. Passive heat-pipe based GPU coolers also exist for ATI's card range, but do take up quite a bit of room in a case. Here we're talking about a real investment in equipment, but the effects can be quite pronounced. And of course, as much acoustic absorption material as can fit will reduce last-mile sound emissions. A musician out here in Boston recently had a G4 case custom built from sound-deadening plastic, with a lot of extra room for airflo and more acoustic padding. Warranties aside, there is no reason to treat any computer like a black box. We don't need to know all of the details of how it is supposed to do what it is doing. We just need to know what it is supposed to do, come up with a better way of doing it (with usually means cutting fewer corners than they did), and trick the old system into accepting the new one.

    This is an odd question. I've never used ProTools, but I have had no problem at all with fan noise while recording voice overs in Final Cut Pro.

    That being said, here are a few notes that should help you.

    The G5's fans are very nicely fine-tuned to CPU usage and temperature. The more heavily you use your G5, the louder they are.

    So you might be able to solve this problem by minimizing usage. Quit your email program, your web browser, and any other programs you have open. Many of them burn CPU cycles even when they appear to be doing nothing. Quit every program other than Protools.

    I don't know much about ProTools itself - I use Final Cut Pro and After Effects - so this is just general advice. If you're playing tracks through your headphones that you don't need for the voiceover, turn them off. If ProTools has a draft playback mode to minimize CPU usage, turn it on.

    If you don't already have it there, put your PowerMac G5 under your desk. It sure looks pretty on top of it, but it will make a lot less noise if it's even a little further from your microphone. In an extreme case, you might want to run long cables to it and store it in a more distant part of the room.

    If you are running a lot of programs on your system, quit everything but ProTools while doing the voice over, and tell it to play a bare minimum of tracks through the headset.

    Put your microphone on a stand and make sure it's close to your face. Get one of those absurd looking anti-poppers (someone at Guitar Center or similar stores can find one for you). Then make sure you're using the bare minimum recorrding volume needed to get a strong signal from your voice.

    Put your PowerMac G5 in back of your microphone. Most microphones are pretty directional. If yours is not, get a shotgun mic designed to pick up mainly what's in front of it.

    I've never had any trouble recording from Final Cut Pro's voice over tool, but it's possible that is less CPU intensive than Protools. If ProTools is the CPU hog, you might want to use your copy of Final Cut (Final Cut Express is just $299) to record the song and then transfer the audio track to Protools. Final Cut is not the be all and end all of audio, but you can certainly lay out other audio tracks and play them into your headphones.

    1: ideal siuation
    If in any way possible AT ALL... i would either place your computing station , or your vocal area in a seperate room (a closet will do just fine), this is by far the best solution for a multitude of reasons... in all honesty you want a recording booth (large closet) with padding (bubble wrap works well, foam, etc...). If that isnt possible, you can do the inverse (a very small computing room with the main room being the recording environment.

    2: A strong possibility
    Place the machine in a closet or place a large and strong divider in your main room... extend a KVM ... or an extension to your monitor cable from behind the closet/divider to a monitor on the other side (in the main room)... wireless keyboards and mice are very helpfull for this.

    3: Remote access
    extend only the audio cables needed from the box behind a closet/divider... and use a seperete computer (a laptop is best) to remotly access your G5... since wireless will work with this connection... your laptop can roam wherever you want, and you can control your session as if connected localy. (apples RDP ... or you can use open source VNC to remotly connect).

    4: if there is no other way
    If you cannot in any way place the box into a closet or a seperete room, then you can build a computer box. I dont recomend this because it can be dangerous to your computer. Basicly create or buy a large box big enough to fit your G5 inside. Create TWO large holes in it (2 inch diameter). Before placing the computer inside, youll want to pad the walls of your new case with carpetting, foam, bubble wrap, cloth or some other sound absorbant material... once complete use one hole to route all your cables through minding the power cable not to be to close to any aound cables (with the mbox, the mbox should be OUTSIDE of the box, connected by the USB cable), once your cables are routed... seal the hole as best as you can with more cloth if possible. For the second hole you can leave it as is... however it's purpose as a ventilation is not well suited to the G5 and should truly be accompanied by a Fan (on the inside of the case) blowing out air through a tube.... which most people fit to go out of their window.

    Many tweaks on this setup have been done depending on the needs of the environment... some people put a real AC inside their computer-box, others simply run their machines in the box, but when not recording, open the front of it. I personaly recomend getting the computer into a seperete room somehow. even if its just a small closet.

    I have a similar setup, only I'm using a PowerBook; however, my roommate's PC is the loudest thing in the world, and we had to figure this problem out, since we both record in the living room.

    So here's a few tips:

    1) Don't even bother trying to use room mikes in the same room with the G5. You might as well just mike the G5 itself. If you need to do room miking, you're gonna need to haul the G5 out of the room and get somebody else to engineer. Period.

    2) If you're doing vocal takes, try not to use bi-directional mikes -- stick with your basic Shure-style unidirectional. Keep the G5 out of the line of audio -- you want it > 180 degrees from where the mike is pointing, i.e. you.

    3) Put it under the desk. Even better, go down to Wal-Mart and pick up some of that mattress padding foam cheap. Put the G5 under the desk and Velcro the padding foam around it like a curtain (not too close, obviously, as you need air flow). You'll find that the noise won't entirely disappear...but it'll be close enough for government work.

If this mic is hand-held or mounted to an instrument (contact mics notwithstanding), this problem becomes even worse, as you now have a moving latency target.

      This sort of trick works well for LF energy (60Hz wavelength is 18 feet). At the top of the potentially audible range, though, 20 kHz has a wavelength of a little over half an inch. That means you have to hold really, really still. At 2Khz (still within the critical range for vocals), you have ~6 inch wavelength. Move 3 inches and you have changed from cancelling out the noise to doubling it.

      Bottom line is that unless you're trying to cut out a low pitched hum, there's little hope of doing it with a separate phase cancellation mic. That's why you buy a unidirectional mic and cancel out the noise locally, in the microphone itself.

While those add some nice processing capabilities for doing real-time effects and stuff, they also mean that you're drawing lots of power off of the PCI bus. Since I believe the G5 takes PCI bus power load into consideration when determining how fast to run the fans, that could easily explain why you're having so much trouble with noise and other people generally aren't.

    If your fans don't have to work as hard, they won't make as much noise. Remember, two 40dB fans will be MUCH quieter than one 50 or 60dB fan, since decibels are an exponential measurement: those two 40dB fans should add up to ~41dB.

    You could make a DIY extra fan port with a drill, but be careful not to interfere with the direction of airflow in your case too much. That'll definitely void your warranty.

    Second, go to your local Staples and see if they carry the Antec noise reduction kit. It should be in the middle of short aisle 1 near the modems and memory, right above or near the Antec power supplies. That's if your Staples is anything like the one I work at. It has rubber mounts for the fans, drives, and power supply. A rubber-mounted case fan is much quieter than one that's just screwed tightly into the metal, since the rubber absorbs the vibrations that the sides of your case would amplify. The product might have been a promotional item for Christmastime but we seem to keep getting them.

    Finally: Check out Frozen CPU or read up on cooling at Anandtech, TweakTown, or any of the overclocking forums.

    Remember, don't attempt any replacements without matching the voltages and sizes. If you don't know your fan's size, bring it with you when you go shopping. Anyone care to post on how to measure a fan? I seem to remember their size being the length of one side, and they are square.

    If the clear air deflector inside the case is removed, then there's less of a restriction to direct and accelerate the air, and that would be a problem.

    If the air in your studio is a little on the warm side (perhaps the studio is in your attic?), then it obviously won't cool the machine very effectively. Run an air conditioner, open the window, or turn down the thermostat for a few hours before recording to cool down the air in there.

When I render a FCP sequence or encode a DVD, or even when my Folding@Home screen saver kicks in, the fan picks up speed too. It is an immediate response - as soon as I move the mouse and the screensaver quits, the fans slow down immediately.

      If you are performing Analalog to Digital audio coversion in software, then you are going to see some increased processor usage and therefor faster (louder) fans.

    The solution here is very simple. You need to isolate the noise coming from the computer. As many people have suggested, keeping everything in different rooms is ideal. That's why "real" recording studios have a control room, a record booth, and a machine room. Since this is not possible in this situation, make it possible with a little sideways thinking.

    We know the computer needs to be in a different room since that will isolate the noise to that room. What's to keep us from bringing the other room into the recording booth (or control room)? Size mostly...

    So bring a smaller "room" into the room. Mid Atlantic has some nice solutions for you. They aren't that expensive. Using an iso-rack in the control room is quite common in most Pro Tools installations.

    I've used Pro Tools in professional situations for about 6 years now. Basically, since the point it became "ready for prime-time" (literally). I work on a prime-time television show. We used to use the AMS-Neve Logic3 and Audiofile system. Then, Pro Tools finally became good enough to use. The problem was the noise. We "stole" one of the Mid Atlantic iso-racks from one of the unused Avid suites, and have been very pleased at the result.

    You have a lot of choices for cooling, some elaborate, some not.

    Anyone who really isn't interested in making a sound-damper box shouldn't bother reading the whole post; it's not that long but it's going to go over a bit too much to display in Slashdot's window.

    This has worked for me. It's reasonably inexpensive and reasonably effective.

    It all starts with a box; you may as well make is some kind of road case; it's not particularly more expensive to do so. Whatever, it's up to you.

    Make the box reasonably large inside; air volume is one means to improve cooling. However, we really can't make the box large enough to be totally effective with air volume by itself; even a closet-sized box will show heat rise. Still, keep volume in mind; you don't want a lot of close tolerances here. I would suggest at least 3 inches all around the CPU, up to 4~6 if you can stand to do it that way. If you can, have air circulation underneath the case as well; it will help a lot with the cooling load the computer deals with (fan comes on much less).

    Dampen the box with a sound deadening material. A "box inside a box" strategy works well here, although expanded foam-type insulation works OK for heat, it's less effective for sound dampening. Fibreglass batts are good for both, but are messy. Thus, isolate the FG from the inside.

    You have an opportunity to reduce vibration-borne noise here as well; try having the inside box rest on something; foam or springs/rubber works. Not too bouncy.

    You should securely mount the computer to the box; I'll leave the details up to you but essentially you don't want it to move. Strategically placed foam might be OK, bracing, zip ties if your Mac has handles, whatever you decide. Think about access to the computer when you want to take it out for maintenance, ugprades, or sitting on your desk when there's no music stuff going on. So, personally that rules out actually bolting the CPU to the case, at least for me.

    You can acoustically vent the box to the immediate outside air to reduce sound transmission. This is hardly impossible, but a little tricky. It probably won't result in a totally silent CPU, but it may well be below whatever threshold you need to record. Lots of experimentation required, some acoustic theory would help.

    I like short term use of a sealed box, mechanically dampened, with a door at front and back. The front door is essentially a full door, to allow optical drive access and moving the computer itself in and out. Seriously consider making the front of the box far enough away from the CPU so that an accidental hit of the eject key (on Macs) doesn't ram the disk tray against anything.

    The back door is a smaller one; it's for access to ports. A plywood or whatever door; hinged vertically. Along the open side (ie opposite the hinge) have a means to let cables in and out. You can construct something simple out of discarded bicycle tubes; a 1" or so wide horizontal rubber "flap" that is open to the door means you can actually get in there to plug/unplug stuff, while the rubber allows cables runs to pass through while still sealing the box from the outside. A double flap or whatever might work better; foam can work, you figure it out.

    Now for my short term location recording: I place a couple of those blue-green gell-type freezer thingys inside the case. Campers use 'em to keep stuff cool.. They reduce ambient temps in the case enough to allow the computer's fans to move cool air around and do the job. Last for a few hours, easy. The box is sealed to outside air and therefore is pretty damn quiet.

    You can also take outside air (vented from somewhere outside your studio) to maintain a more permanent solution.

    When you're done, you should have a case with a latching door at the front for access, closed the rest of the time for silence, and adequate cooling in short-term recording to keep your wallet cool. In a very general way its like a little 'fridge. Cable in-out shouldn't be a problem and ther
