My friend was installing his new heatsink/fan combo that he bought a while ago. He removed the stock one from his computer, and cleaned it up. He then put some arctic silver on it then I watched as he put the heatsink/fan onto the processor. We fire up the computer and it climbs to 80C+, within the first minute... not too good. His temperature monitor, probed in between the pins of the processor, like before, reads that 80+. Before it would give a good reading of arround 37-50C. Is there some sort of a wait time when changing the heatsink and adding a thermal compound? Whenever I assemble a computer, I always do that first, then hook up the mobo into the case, and work on from there... usually an hour or two elapses but the computer is fine... this one worrys me. So what do you guys think?
