Looking for a set of good silent fans. Planning to use them on my radiator and most of my system in my next WC build, but I figured this sub would have better opinions on fans then they would. Going for a quiet system, so ideally I want fans close to 1200rpms @ <30db. Currently I am looking at the cougars, they seem to get great reviews but I've never used them before. Any advice would be much appreciated.
