Tim:
Overheating is always a failure of the cooling system.
Mike McCarty:
I never said otherwise. Of course it is.
Well, you were certainly arguing in that direction with my post that you got your knickers in a twist over. I'd argued that whatever the reason for the overheating (faulty, or normal use of the computer), the cooling needed fixing. You were *only* being concerned about what the computer was doing at the time.
It doesn't matter *why*, at that stage. If the computer is overheating, the computer *is* overheating. *That* has to be addressed, and the computer has to be built so it doesn't overheat, even if run at 100% continuously.
