Hi, I recently built a budget computer and I am having some difficulties trying to figure out which of my fans is causing all this racket. Any help would be appreciated. I have a Rosewill Galaxy-02 with three fans (not sure what the bearings are) and my Athlon x4 760k stock AMD heatsink fan which I suspect is the culprit. I also have my 650 TI boost's fan if that could be the problem. Thanks for the help.
