So, forgive me for the obvious question, but did you plug the fan cable back in again, and into the correct socket?

Yes, if you remove the heatsink, the thermal material needs to be re-applied. You may have noticed a white/grayish substance on the chip surface and heatsink when removing it. That is the thermal material. It ensureas that their are no air gaps between CPU and heatsink, since air is a very poor conductor of heat. No paste means that the CPU will overheat in a very short amount of time.

I suggest you purchase some paste and then read a good guide on how to apply it. I can talk you through the steps as well if you like.

I've never used one of those, ever. You just have to be careful and remember to earth yourself against the case before touching anything.
