CPU Overheating Damage

[iGPR3]

My friend’s i7-4790K has been thermal throttling like crazy for the past month or so. Yesterday he told me his PC had been shutting down randomly for a while, so we checked HWinfo and it was consistently over 90*, even at idle. I had a look at his PC and one of the corners of his CPU cooler mount had snapped, so it wasnt making contact properly.

 

How much damage will this have done to the CPU, if any? And will this affect the performance? Thanks.

It should throttle and protect itself. I'd mount the cooler properly and see if it still works. Likely it's fine. It will either work or not.

minimal damage, because thermal throttle is designed to protect the CPU from thermal damage. It's better that the PC was shutting down, because it was basically hitting the emergency brakes.
