The screen went blank ?

The CPU has THERMTRIP. If the temperature goes high enough (implying
the heatsink fell off the CPU), the CPU sends THERMTRIP to the motherboard
and THERMTRIP causes PS_ON# to be deasserted. That shuts off the power
and removes +12V running VCore. The fans should go off.

The CPU protects itself.

I have an E8400, which is 1/2 of a 9650. It draws 11W at idle and
43W flat out. Your processor would be double that amount.

Maybe your VCore is a bit too high ? The joint between CPU and heatsink
would have to be absolutely dry, for it to get that hot. Even with
a tiny heatsink with fan running, it should do better than that on
cooling. For one thing, the CPU uses throttling to try to avoid
a temperature that high. And that's one reason why it shouldn't
be hitting 126C. It has one defense mechanism, that reduces CPU
capability as a tradeoff for temp. To hit 126C, you really need an
air gap between CPU and heatsink. Like if the push pins aren't fastened
or something.
