Did you get a warning, or did you just decide to stop the test? Did you continue the test and see what would happen? Did you, when the temperature got up to 95°, check what the CPU's clock frequency was? The easiest way to recognize thermal throttling is a reduction in frequency while at 100% utilization. Or did you just assume that, with a mere five degree buffer and your own personal analysis, that the CPU was just seconds away from total destruction?
