Just installed the new case fan. Didn't make any difference in CPU temp
But it definitely is spinning. I installed it as an exhaust. But I cleaned out the CPU fan and heatsink and the peak temperature dropped 20C!

Kiljaeden said:Also look at what thermal paste you use on the CPU. If you can, grab some Arctic Silver thermal paste. It should lower the temps by at least 5-7 degrees.
Have you got an 80mm fan at the front to push the air in with the 80mm fan at the rear as an exhaust? Sometimes it can cause air flow clog with no front fan pushing the air to the back.
