My friend has a non over clocked i7 7700k and he said his PC would freeze and crash a lot and I assumed it was his cpu over heating and when he downloaded HWmonitor his non over clocked cpu was running at 84c at 20% usage. If I am not mistaken that isn’t to great and when he started to play a game his temps got as high as 95c. He has plenty of room and air flow in the case and a water block on the cpu so my fist thought was that the pump is broken but it’s a fairly new pre built system (surprise lol) so my next thought was thermal paste but I don’t know if bad thermal paste could affect it that much so now I don’t know what to tell him. I think that it may be overclocked without him knowing so would I just check that in the bios or is there also a software I could use to check. Any suggestions or advice is greatly appreciated thank you for your time.
