+1 on attacking the problem at the source: get quieter components inside the case. After that, you can also make the case absorb some noise internally, this helps too. For example, I have an Antec Sonata case lined with Acoustipak. It took a while to apply, and was a pain to do because you basically have to take everything apart and rebuild from scratch. But it helped. A couple other things: - Do you hear vibrations from the drives or fans causing your desk or shelf or whatever the case is sitting on to vibrate as well? Put your head near these surfaces and listen. It can help a bit to put the case on something absorbent. I used a piece of dense foam. - Do you hear a lot of fan noise at the back of the case near the PSU and/or case fan? Even "quiet" fans (like I have) are not silent. I was hearing some fan noise reflecting off the wall behind the case. So I found that it made a slight but noticeable difference to put a large square of sound-absorbing foam on the wall directly behind the case. My computer is still not silent, but it's pretty quiet. -- Paul Winkler http://www.slinkp.com _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
