I've been experimenting with getting my computer to make less noise. I'll talk about the stuff I've done so far. As far as the case mod goes,I took a mid-tower case that was less than 19" high, with side panels that slide off( a 'U' shaped cover was no good). I stripped the plastic front off and removed all the drivebay frames from inside the computer. I wanted this to be rackmounted(thats why less than 19"). So far I've glued rubber matting to the inside and anyplace else that would not interfere with airflow and internal equipment. I attached an aluminum front(with mounts to hang my J-Station )and aluminum 'L' brackets on the sides for rackmounting. All rivets were drilled out and machine screws with rubber grommets were used. The big noise reduction came from a different approach to CPU cooling. I took a high performance all copper heatsink, a Thermalright SK-6 and tossed away the high performance noisy damn fan. AMD XP Thunderbird proccesors run cooler than the older ones which ran much hotter. I picked the Athlon XP1600 over a 1900 for less heat(and less money). Using high performance silver based heatsink compound (Artic Silver II) and a slower blower type fan blowing accross and through the copper fins instead of over the top, I was able to get much less fan noise, yet stay within AMD heat specs. I actually saw this done in a one rackspace server, but with many more fans. The one I got was from Radioshack, 12VDC. The two hard drives are mounted to the slide off top cover using machine screws and rubber, and the CDRW is the only front accessed drive. No floppy drive. The 400 watt power supply has dual ball bearing fans and is very quiet. So far the machine has been running rock solid, with a SeaSound Solo handling the sound. These are the first steps I have taken, I know there must be better ways. Suggestions?
