CPU Temperature required for auto-shutdown

bioscpumotherboard

At what temperature do most motherboards/cpus power down to prevent damage?

And what determines this? Is it the bios, the motherboard, the cpu itself?

I have a cpu that stays on in the bios until about 105 C and then shuts down. I am not sure if this is correct? Maybe the sensors are wrong. I think 105 is a bit high. I guess 80-90 would be more reasonable for an auto shutdown.

Max CPU temp is entirely dependent on the model of CPU. The manufacturers make these values readily available on the spec sheets and white papers for each CPU. Most aftermarket motherboards have the ability to choose which temperature an overheat shutdown occurs at. Most vendor-supplied boards (from Dell, HP, whatever) have this feature locked at the recommended value for the CPU that ships with the computer.
