I have a n H100 on my CPU now, and after a few days replaced the stock fans with two Cooler master fans due to noise. The CM fans are rated for 69 CFM, and my CPU does run a 4c warmer on idle and about 10c warmer under 100% load test. The stock fans were rated for about 90 CFM I believe. Does anyone know of some good fans that can move air, but are also not as loud? I want good high-end fans. The last few I bought; the bearings wore out quick. Thanks guys!
