{Pictures Added} Need advice silencing a generic case - a rough guide

post #1 of 8
Thread Starter 
I have a spare PC
Specs:

AMD Athlon X4 9600 2.3Ghz
4gb DDR2 Corsair (2x2gb)
CM TX3 Cpu cooler (92mm fan in push)
ASUS M2N68-AM-SE2
Logysis 480w PSU
Generic Case (looks like mid tower case)
1x Samsung 500gb F3
1DVD
9600gso XFX(not fan control)


Right now the case has 1 fan on tx3 in push only. there is1 more on the rear exhaust at the same level as cpu fan. then there is 1 on the side panel. along with a little noisy 9600gso from XFX ( no fan control runs with a modded 2 pin voltage converter mod via molex.)

Anyways, the point is that it runs very loud. I would like to make a really cheap silencing solution. So I went to dollar store and got 15 x small foam pads (3mm thick each x 7" x 3") for a two bucks. I also have a few meshed wool sheets (14" x 16")

Do you guys think if I just stuck those foam pad with a tape and placed the mesh would it be significant in dampening the sound ?
Or should I get thicker foam pads.

My main purpose is to reduce sound coming out of the pc. I will be covering insides with foam pad. But I will not be blocking any vents. Because its a generic case anyways with only two fan mounts. one on rear and other on the side panel.
Also is there any other alternative to sticking foam pad with tape ?

With my plan of action, do you guys think I will be able to achieve some silence. I will be posting pictures in a few hours. Once I get to it.

I made this rough guide for people on extreme budget

Things needed:
5 x wool sheets (Walmart- crafts section) : 20cents each x 5 = $1
15 x small 3mm thick Foam pads (Family dollar): 15pack pads = $2

Charges not included:
gas, electricity and double sided tape, soldering iron


Pictures Added

Cut the wool inserts to mount on the home

448

Stick the inserts with double sided tape

448

Prepping to make holes in the wool insert sheet with a soldering iron. Could not figure out any other way. ??Any recommendations ? apart from burning with fire.

Hole production made awful smell

700

Mounting the new antivibration fans

448

Place the cheap foam pads on the interior of side panels

448

make sure there is place for vents

448

Covered it with the wool sheet to absorb additional sound as well as provide some passive cooling thru vents. For this, I stapled the wool sheet to the fad below and used double sided tape to stick the pad to the side panel.

448

Panels finally done.


This helps me quite a bit with reduction of sound. Its not completely silent. But It is much better than before, when it sounded very loud. I can still hear some sound, but that's just the XFX 9600 GSO which has no fan control, but I volt modded the fan connector with a molex to run at 50% of its speed. So that's probably the only thing making noise.

Hope it helps others to do things on a budget. I spent total $3.00

Or buy some sound absorbing foam, it isn't too expensive for some decent stuff, compared to what we spend on our pc's, lol.

New fans? May not have many fans in your case but they can make all the difference.

Yeah, I was looking on getting new fans, cuz actually they are the ones making noise, but since it is a spare PC, I really dont want to spend money on it. Trying to make it extreme extreme budget silencing task. smile.gif I will try to find some sound absorbing foam near by if I can find it for cheap.

I added some pictures and a rough guide in the initial post for those wanting to try it out. smile.gif

That's actually not a bad idea with the wool corners on the fans wink.gif

How is the sound now? Any better than it was before?

Its actually much better, I really can't hear the rear and front fans at all. I might still need to do something about the 9600gso. But since the card is working fine, and has warranty from xfx I am hesitating to open up the heatsink. All I have done is simple wire mod, which is like adding extension to it without cutting anything and running it via a molex power rather than graphics pcie's power.

Temps are fairly cool for an Athlon X4 9600 too. Its running at 32-34degrees idle. and about 59 at loads.
I am happy so far with the improvement I achieved for 3bucks.

Not bad at all then, especially for $3.
