The CPU is excessively hot because of the increased strain from overclocking, which also negatively impacts performance.

Follow MasterMace's advice and verify your voltages. Also inspect your fan speed on the CPU cooler. Often when it's set to auto, certain boards increase the CPU voltage when boosting the multiplier. Keeping the voltages around 1.4v would be ideal. Regarding overclocking, I don't see much benefit; the minimum power requirement for that card seems to be about 550 watts on your PSU. You can then adjust defaults in your BIOS and proceed from there.
Because the cpu is already cool, changing the cooler or TIM seems unnecessary. The only software that reliably works with AMD processors is Overdrive. Overdrive shows a thermal margin of 55C, meaning it can reach 55C hotter before any issues arise. Small thermal margins indicate a heating problem, not major ones.
Just share your bios temps, voltages and fan speeds. There appears to be some confusion. The Super IO chip (ITE 8620) has been reported to have issues with sticking sometimes.
