acoustic foam
Is there anything special about the acoustic foam used in computer cases for dampening noise? Can I use any sound proofing foam found in car stereo supply stores or Home Depot? I found some at my local CompUSA for $20 (I think 4 sheets: 2 17x15in and 2 17x7in). Anyone tried them? |

I've read a lot of articles that said it won't help that much. You're
better off with a good, solid case with rubber rings around your screws, etc to reduce vibration. The acustic foam can't really help with load fans blowing out the back (which open holes for any noisy components inside). Check out http://www.quietpc.com/ . They have some "Acoutic foam" if you want to compare the dimensions to your Home Depot foam. Good luck! --Mitchua "Rocketman" wrote in message ...

I coated my case with Akasa foam and it is quieter, but the sides of the
case no longer cool the air, so the temps are higher. If your cooling isn't marginal to begin with then it's ok. -- Ed Light Smiley :-/ MS Smiley :-\ |

I think there is a company called akasa that sells matting material to
deaden sound. It seems like the thicker the case walls the more sound it could absorb. I was looking at this once and was at a site that sold sound obsorbtion material to line automobiles for people who want to drown out all the road noise to increase stereo quality. That might be something to look at. You could just but shag carpeting to scatter the sound to reduce the resonance of a metal case. A lot of noise is cause by metal cases being flat and cavernous. Maybe if you could make some baffles at the front the sound would not come straight out of the front ventillation. If it had to sneak around a couple soulnd obsorbing panels maybe the would cause the sound more trouble getting out. When you think about it, a guitar is a cavernous container that is designed to amplify sound. A case can amplify sound like a drum or a guitar. Having fans only on the back of the case may help. If you mod a case by cutting out the back of the circle and using a grill probably will be less vibration from the fan. The air strainging to get through those small circles can acutually cause more noise. "Rocketman" wrote in message ...

If your speaking of Dynamat, I used it on the sides of a case that had some air holes drilled near the front. Could hear the hard drives activate and all sound 'came' through the so called vent hole. Case is an Antec model...don't recall the number off hand. Just be careful when you apply it. I used a roller to smash it down as thin as possible so the case sides would slide back on and clear everything, only to have it come through the air hole toward the outside. Made a hell of a mess...finally got it cleaned up! Case is much quieter now however. Computer runs cooler now with a front case fan and one back case fan (plus power supply fan) both stepped down to 7 volts, than it did with the open 'breathing holes'. ....Allen |
