Not sure if it would work but www.quietpc.com has some computer fans that are supposed to be quiet.
Quiet fan for rack cooling installation?
I just bought a Plinius amp that runs very warm in class A. I have 6 inches of space above it and open sides and front in my rack, but the heat buildup is still immense. I'd like to install a small, silent fan in the rack to help keep things cool. Could you folks please make some recommendations based on your experience?
Cheers!
