HI all, I'm trying in vein to build a quiet PC. I currently have a SilenX PSU which is silent, SilenX CPU cooler (can't hear a thing when the cover is on), and a single 80mm SIlenX exhaust fan. My problem is the noise the exhaust fan makes, the fan itself is silent but there's a lot of wind noise and I have no idea how to silence it ? ANy advice would be greatfully received. THanks ! Paul.
