What i've found works well is to buy a fan adapter that will allow you to use a larger fan (such as a 60mm fan on a 40mm heatsink, 80mm fan on a 60mm heatsink, or a 120mm fan on an 80mm heatsink). Then get a fan of the larger size that uses magnetic levitation bearings (they tend to be considerably quieter than ball bearing fans, though slightly more expensive). Then get an adapter for the fan that will run it at either 7 or 5 volts (Zalman sells some of these for roughly $3 US). So then you use a larger fan, but run it at a slower speed. It will end up pushing about as much air as a small fan at high speed, but make a lot less noise doing it. I recently managed to make a system almost silent this way; i can still hear it (mostly the hard drive noise) if my head is within a foot of the case but otherwise cannot. -- ------------------------------------------------------------------------ Dan Ramaley Dial Center 118, Drake University Network Programmer/Analyst 2407 Carpenter Ave +1 515 271-4540 Des Moines IA 50311 USA
