Hi guys, i'm building a new rig and I was wondering if I need a CPU fan for my X4 Phenom 955 BE. I'm gonna be playing newest games on high graphics with my MSI GTX560 ti Twin Frozr. I'm planning to get the Arctic Cooling Alpine-64 GT or the Arctic Cooling Alpine-64 Pro since they are cheap and I can't afford more expensive ones. But is it necessary for me to get a cpu fan? And if it would be better to get one, are they going to be loud? Cos im looking for a quiet rig.
