I used 2 copper heat fans with heat pipes from thermaltake, and put some 90 mm fans on each cpu/heatsink. I also put a new case around them to improve air flow. You want more air being pulled out of your box then going in. I manually monitor and control the fan speed and with the new setup I have been able to get the processor fans rpms down to 1800-2000, a real help to reduce noise, with the temp averaging about 46c when idle. When I have done something, perhaps emerge some program, whatever, temp goes to about 50-52c. Check the specs on your processor to see what the operating temp range is so you do not burn things up.
