A friend of mine removed his heat sink and put it back on without reapplying thermal paste. Is it fine to do that?

As a general principle, no, that's not a wise thing to do.

As for what the actual result will be, that can vary between being lucky and having it not make much difference to the operating temperature, and causing the component in question to run much hotter.

I suppose this was the CPU heatsink/cooler, or was it something else like the video card?

I pressed F5, and I'm feeling refreshed...

Yes, the processor's heat sink. He has now reapplied some thermal paste. May I ask, how much is the highest temperature of a core 2 duo processor?

That depends on the specific processor, which one is it? They typically vary between 60-63 degrees celsius depending on the model.

my memory is a bit off it seems, the max temperature for that particular CPU is 72 degrees Celsius or 161 degrees fahrenheit. I forgot intel CPUs can run hotter then AMDs, in the past (pre core2) AMD was always the hotter running CPU, when the core2 came out they made kind of a reversal.
