Ok, I reseeded the fan, applied new thermal paste, increased the fan speed, and improved the air flow in the case. Also, I mounted the CPU fans towards the large fan at the top of the case. Asus probe is know reporting the following:
[Overclocked at 3.0GHZ] Those numbers are obviously good, but there seems to be a bit of a spread between the cores. Here are some numbers after running a run-in test for a few minutes.
Are the core numbers ok? Is core 1 and 2 two high compared to 3 and 4?
