I thought you said you already updated your BIOS?
As BigDog said, you need to apply new thermal paste everytime you remove your CPU cooler from your CPU. Guarantee that's why it's running hot, and possibly why you're seeing lower FPS, because it could be throttling itself to compensate for the heat.
You'll need to clean the old paste off first before applying new paste. Do this by using coffee filters (because they're non-lint and super cheap to get for a large amount) and isopropyl alcohol (the highest percentage you can get... 90% or more is recommended). Just wet the coffee filter a bit with the alcohol, and then wipe away the paste on both the CPU and the cooler's heatsink.
After that, apply a rice-sized dot (too much will give you issues) of thermal paste in the middle of the CPU and push the cooler back on top of the CPU, and secure it. The weight/pressure of the cooler and clips will spread out the thermal paste evenly itself.
