I have a thermalright 947u heatsink, with a very loud 80mm thermaltake fan on it, could anyone recommend a quiet 92mm fan since im able to use this size. I use a large case with 1 intake and 2 exhaust 80mm fans that keeps it pretty cool, also I running a stock amd xp2800 that idles approx. 42c and 48c under load. I feel a bigger fan wont need to run as fast, so I hope I can quiet this thing down since the cpu fan is all i can hear...any suggestions will be greatly appreciated.
