I'm a bit stuck because I need a new cooler for my CPU which is an AMD FX 8350 because it is too loud - I looked at the CM Hyper 212 but it is too big for my case - then I saw the Be Quiet Pure Rock Slim - My CPU has a TDP rating of 125 but the pure rock slim has a TDP rating of 120 - is that ok or do i HAVE to get a fan of at least 125 TDP - not looking to overclock or anything i just want to be able to game with a much more silent fan. Hope you understand, thanks
