The processor you've picked is designed for overclocking. the phenom 2'sr un somehwat hot to begin with, and the AMD stock coolers are barely adequate for the processors at stock speeds. Once you start increasing the voltage for overclocking, the stock cooler won't cut it. NTM the stock AMD cooler fan is loud.
I'm getting the idea you don't plan on overclocking, which is why I suggested you look at the builds in my sig.
