If your CPU fans heatsink is not flat and your CPU is not flat, not having thermal paste will cause it to get very hot.

Even if they were both near perfectly flat you need the thermal paste to ensure that the tiny grooves are filled and the heat is properly transfered from the CPU to the heatsink.

It seems like thats your problem, that your CPU is getting too hot. Hve a clue what your CPU temps are running at while doing this?
