funny looking back at this, i was still a noob, never tried anything but the stock cooler, and now i'm building rigs for people..
I think if you really want the best aircooling possible, get the noctua, take off the fans and use them somewhere else in the case, then put tacens ventus II(€25 each) fans on it, i used them on a customers rig, it was completly silent at 12v, and the amount of air they moved was more than i ever saw
