So I have an athlon 64 x2 5600+ Brisbane. I also have a zalman cnps8900 extreme cpu cooler. But my idle temps are 30's/40's almost in 50's. When I run prime95, the highest temps I get are 72 and that's after running it for 4 hours. When I play a simple game like minecraft, my core 0 is 50c and core 1 is 60c... I don't know what's wrong
