Most cpu's have safety systems built in that throttle the cpu when the temps reach too much. I think the average throttling temperature for most CPUs would be 90-100 Degrees centigrade.
The only way I can think that you could really have gotten your temp to that high is by running it at 100% for a few minutes then shoving your finger in the fan and quickly getting the temp.
Agreed Nubius, you guys do realize 100 degrees Celcius is boiling point. Believe I have had this happen, the CPU died. Just close the thread Nubius, this is retarded.
