Hello

Does anyone have any experience with sound proofing a PC Chassis. I have a Cooler Master HAF X with plenty fans and ventilation, its generally silent but the GFX card fan is dam noisy.

Looking for some kind of dampening or diffusion mat I can fix to the internal walls to provide some relief.

Try plastazote foam (memory foam).

Get a cheapie yoga mat and cut it up.
 
Get earphones. That case has lots of mesh and fan holes everywhere and you are not going to cover them up.
 
Use speedfan and set up advanced ramping. You want to get your case ambient temperature as low as possible without being noisy, so spacers for fans and a baffle for the gfx card would be best.

Dynamat and its equivalents (T-mat is excellent value) damps mechanically transmitted noise, the radial blower on a loud gfx card is acoustic noise.

The most effective way to quieten down a graphics card once you have proper ramping is to feed it ambient air directly and bypass the case temperature rise so that the cooler has a lower base temperature to work off.

Otherwise, build a mechanically ventilated plenum damper for the rear of the case.

If you want to build a custom baffle for your case to split the gfx from the CPU and remainder of the case, you can get foam core signage type material and do a quick superglue/resin job which will make it keep its shape.
 
Now thats a good reply.

The issue is the gfx card fan, its noisy and without it going at about 40% the temperature exceeds 70 degrees. Not so bad in winter, but summer is hell. The PC is in a common area, so it annoys everyone if the the noise is loud.
 
Where are you located? Might be able to point you in the right direction (if you're in Pta I have a CNC router too). Perspex can be softened up with a hot air blow gun/in an oven and formed over a quick and dirty mold.

I aim for my 5850 to not go above 85 under high loads, typically it levels off at around 80. I know the sweet spot where it starts to get obnoxious and regulate the case fan to ramp up (eg one for CPU, case ambient and GPU temperature and take either the max or the SUM of the ramps) once it gets there. Speedfan allows you to have multiple channels feed its ramps, highly intelligent and far more effective than knobs on a 5.25" bay. Just have your fans run off the motherboard.
 
Don't. Its a complete waste of time. You stick foam everywhere, it does nothing and then you can't get it back off.

The accoustipac stuff works, I've used it before but it's a bit pricey. It has a solid rubber like backing (with two different foam layers on top of it) which peels off easily. Silent pc review did some tests with it before, will try and find the link. It damps mechanical (heavy rubber backing) & accoustic (dual foam layer) noise.
 
Nice that sounds great.

I realised that half the problem is my stock setup. I'm now looking to get hold of an Arctic Accelero Xtreme II - anyone know where these can be found ? Or of any IT distributors in Cape Town. Frontosa doesn't have anything related.
