getting rid of computer noise (OT about closets)

Post by pieter » Mon Dec 31, 2007 10:05 am

hi there
are there closets on the market, built for desktop computer? i'd like to hide it somewhere to get rid of the noise when recording. and no, i'm not handy enough to build one myself :?

It's best just to build a computer to be as quiet as possible.
Get a case that uses 120mm fans, a PSU with a 120mm fan, etc...
Use intel c2d CPUs rather than AMD, they run cooler and your HSF won't have to work as hard.

Place some high frequency absorption panels (or broadband absorption panels) on the wall where the PCs back panel is aiming at to kill some high end noise.

I'm so excited

the quiet computer solution is a good one, maybe I should just get some mac minis or macbooks

but

since I've been forced into a complete basement remodel, I'm getting to build a little media closet, where the computers will live.

probably will get some kvm over ethernet boxes..

I putted my computer out of my room


excellent low noise solution for home recording if you can do it :).

yeah

but they are pretty expensive as I remember. ~ $250-300 ??

also I wonder about the quality of the signals.

but I might get one to see!

ouch

even more expensive.

I see a combo of devices to extend 1 vga and 2x ps/2 330ft, adds up to about $400

:oops:

This should probably be some kind of sticky...

First one that comes to mind

There are a lot of others; do some searching amongst these forums

At low CPU load my overclocked AMD X2 + overclocked Geforce 7800 GT runs quieter than the noise-floor of my Yamaha HS80M monitor-speakers.

Like someone said before, use 120mm fans, but also use a chassis that offers enough room for air-conduction when using a desktop. Clock down your graphic-card's GPU to 100 MHz when you are working in 2D. Use a good and efficient PSU that not only comes with a 120mm fan but also doesn't produce to much heat of its own. In a desktop computer consider putting your harddrives on some kind of foam and make sure that no part of the drive (and possible no cable-plus either) touches the chassis.

Slow down your fans under low workload. Use a mainboard that either offers to control the fans via BIOS itself or if under Windows use the application "Speedfan" to control your fans depending on temperature.

Use a bigger and quieter fan for your CPU, chassis and graphic-card. Use passive solutions only if your graphic-card is rather low powered, because in a standard ATX chassis these will spread their heat up to the CPU mainly. Use a tower-cooler for your CPU, this will help air-flow in your chassis alot. If your chassis has any holes at the sidepanel then close them either completely or with some foam. Chassis airflow doesn't need any holes from the side-panel, it's even bad for air-circulation.

My 120mm CPU fan and rear chassis fan run at only 38% and my Zalman VF-700 CU GPU fan runs at only 25% under low workload. My current CPU temp is at about 36°C and my GPU at about 50°C. Under heavy load the fans increase their speed to 73% and 66%. The CPU/chassis fans have a maximum speed of 1200 RPM at 100%, the GPU fan runs at 2800 RPM at 100%. I replaced the 120mm fan of my PSU with a slower model.

When CPU, chassis and GPU fans are running at 100% I cannot hear them over music playing at about -30 dB fader setting (0 dB = about +4 dBU with setting the HS80M to 50%/+4 dBu volume). When they run at their normal 2D high workload rates of 73% and 25% I cannot hear them over about -50 dB fader settings. Like said before 38%/25% is less noisy than the noisefloor of my active monitor speakers.

This is an all overclocked AMD system with a 3D gamer's graphic-card, heavily overclocked RAM (DDR400/2.6v running at DDR566/2.9v), two hard-drives (of which the Raptor runs at 10k RPM), all PCI slots used, three of five 5.1/4" bays used. Newer systems using Core2Duos and less drives should possibly run cooler even.

If you're building a PC, here are some (admittedly fairly obvious) suggestions:

Use Corsair power supplies. They are all high quality, have long warranties, and they're damn near silent. Properly quiet. I have a 550W model in my music PC and I just can't hear it.

Use low-end, passively cooled Geforce cards (but avoid "TurboCache" models), or on-board video. Don't use Radeons, you'll only end up in driver hell.

Core 2 Duo processors are preferable, they run at low temperatures, and provide a lot of power-per-watt/$/£ etc. I have a Zalman CNPS 9500 cooler in all three of my main PCs, and they're very quiet when turned to their lowest speed, but if you have the case space, a Scythe cooler would be even quieter.

Look for motherboards that have passively-cooled north/southbridges (which is most of them these days). If firewire is important to you, ABit use Texas Instruments firewire chipsets, and usually passively cool their chipsets. Asus are also good but for some reason skimp by using VIA firewire chipsets. I haven't had good experiences with VIA firewire cards.

Western Digital hard drives seem to be the quietest, whilst still having good performance. Next choice would be Samsung but I've seen a number of them die and they're not as fast. Avoid Seagate and Hitachi.

My Asus A8N Premium uses a Texas Instrument Firewire chipset, so you have to look at the specs to find out which Firewire chipset is used.

Thanks for posting this, Timur. I wasn't aware Asus used anything other than VIA chipsets - I'm pretty sure that's what is on my P5K-VM motherboard. Irritatingly. (Might be limited to their P5x range?)
