I am using a AMD recomended cpu fan, a case fan plus the fan that is in the power supply. I leave a side off and I can drop the temp by 3. I don't over clock, but have a problem with the ATI expert 128( not Pro ).working right even with all the up dated drivers.I ahve a problem with games like , flight combat freezing up the PC, and running over 16 bit colors. I like the A7V and the 800 bird. It seems to run flawless except for the graphics card. Bruce
