trust me, the stock 955be cooler sucks. it sucks horribly. temps are always too high and as soon you utilize the cpu, the fan speed and noise skyrockets. IMO the stockfan is useless. you need to buy yourself an after market cooler. i chose the Mugen 2 from Scythe. it's the quietest cooler i've ever seen. it keeps even my overclocked phenom cool.
