haha i have the phenom 2 940, im using the Thermalright ultima 90 with the antec 900 case - the side fan is attached. thats why i chose a smaller Heatsink. im getting 30 - 33 C doing normal stuff on my desktop ( music, web, msn, and whatnot. ) i did overclock, 3.5ghz 1.4v so.. i would recommend the thermalright ultima 90 if you have a fairly small case
