Hey, I have a 4300 w/ the stock cooler and a ga78lmt-usb3 @4.2ghz and idles in the High 30's and under load at 60. I have a 2gb HD 7770 and my temps are great, but my PSU, fans, and GPU is so quiet, The CPU cooler needs to be changed out. I don't want too much overclocking, maybe 4.3ghz, and I'm looking at the arctic aalpine 64 pro rev 2.0, and my case is the rosewill ranger m with front 120mm fan and rear 80mm fans @7v.
