My 2800+ with the stock fan was getting about 58c full speed(loud) and 63c at medium(tolerable). I cut out the grill and got a 5c drop. Then I put my torin blower on the back, which is about silent, and right now under full load my temps are...48c. Power supply is 49c, hard drive is 38c and case is 37c. You might want to mod the psu, as it gets extremly hot at stock. With the stock cpu fan at medium i was getting 7c on the power supply.
