The last time I had a heat prob, my pc would emit a quite, but constant, "Beeeeeep" and shut down after a few minutes. When I rebooted I was told I had a hardware prob but pressed F1 to continue. It would run fine for a day or two then act up again. The reason I ignored this was I had just replaced ALL my fans about 3 months ealier. Also, my case was cool to the touch.
Eventualy I entered my bios and saw the CPU temp highlighted in red and it's fan speed was eratic. Replacing the CPU fan fixed it. I guess you might want to enter your bios to check your *true* temp?
