Actually the thermal cut off is 90C as it approaches that temp the heat increases exponentially as more and more energy is lost as heat in the conversion though the walls. This effect is amplified the thinner the walls are and thus the lower the nm value for the given chip.

On another note I think he said it was a laptop. Unfortunately almost all laptops have terrible cooling which is why I will only buy alienware b/c of the additional cooling they have.

Also your temps should not go above 60C when at max use to be safe. But I can say that the thermal cutoff for the latest intel chips does work as I have run mine with NO COOLING and it still works after the thermal limit was reached and it cut the power.
