AMD Phenom II 720 has a core at 95°C?

Hello,

I just built my first computer and it ran without a hitch. I downloaded Speedfan to check out my temps without the case on (curious since this is all new territory for me). My temps come up fine (around 35°C) for everything but one of my cores. That core seems to always fall between 95°C - 100°C!

This seems grossly incorrect since the system is functioning fabulously without any issues. The only thing that I can think of is that I messed up with placing the CPU heatsink. When I tried placing it, I put it on backwards (my fault for not paying attention to the clips). I had to lift it off the CPU to place it correctly, which I think may have messed up the thermal paste.

Specs:
AMD Phenom II 720
Biostar TA790GX XE (micro-atx)
