A:Answeri just used this fan to replace an older coolmaster hyper 212 4pin wire. it doesn't have the clips on the sides, so i pressed the long screws in between the fins.
A:AnswerIt's not the quietest fan out there, but for the price it's pretty solid. I have two of these in my PC and one NZXT one that came with my case, running two of these is about as loud as one of my NZXT ones. So while it's not the most quiet it's still fairly decent and won't generate too much noise.
