Ouch and btw I've done some torturing on one prototype (AMD). It had thermal at 98Celsius (specs for this cpu said 95C max), and I ended my test at 105Celsius. I do not know about TM1/TM2 etc, but in this case hardware clearly failed to do the right thing.
This is dependent on the CPU/motherboard in use - AMD CPUs (up to the last ones I heard about, anyway) don't have any built in thermal protection, they rely on the motherboard to shut down the CPU in the event of over-temperature. Intel CPUs since the Pentium II all shut down on excessive over-temperature; Pentium 4s will also clock-throttle to continue operating before they get to this point.
