My question is whether or not the motherboard or CPU is responsible for shutting down the pc if the CPU overheats. Hence, why I asked this in the CPU forum, I could have asked in either. Also, if mine will auto shutdown if the CPU temp is too high.


Another question I thought of, how long would the CPU run if it were @ 100 celsius?


CPU: i7 6700K

MOBO: MSI Z170a M5

Usually if the cpu gets too hot it will begin to thermal throttle, meaning the cpu will become slower moving to lower clock speeds to reduce core temperatures. It's based off both the cpu and motherboard, the cpu has the thermal diodes and the motherboard reads/interprets them. Running the cpu at 100c isn't a good idea, that's nearly to the point of thermal throttling. Eventually it will degrade the cpu and it will have a shorter lifespan as a result.

Rather than worry about whether the motherboard will shut it down for you or how long it will run while essentially overheating it's best to use a program like realtemp and monitor your temps. If using an appropriate and sufficient cooler this shouldn't be an issue you need to worry...

Some good information here regarding ambient room temps and cpu core temps.
