Well i had some cpu heat problems with my new 2400+, it was running around 55c at idle! with the side of the case off. So i just installed a cooler master HAC-V81 and at the top end it does 62.8cfm, but produces a whooping 46dba at full on. It dropped my temps about 10degrees celcius on average. But thats switching from a amd oem heat sink and thermal tape, to the huge HSF and thermal paste....just thought id let people know how this HSF did for me, still new hehe and still have way less fans than I want. Im now running around 45c at idle, and plan to add a few more fans in hte next month or so....this site has been a awsome source of info...thanks guys
