I have a i3-3225 cpu with a corsair CX-430 psu. the case is a fractal node 304. MB is the ASrock H77M mini itx. Everything is stock fans but for some reason the cpu fan is really loud. I returned the cpu/fan at the store for a replacement and the replacement was just as loud. I cant figure out if its the mb causing the fan to be so loud or if other people are having the same problem with the i3-3225 cpu's.
