Would think that it would be a cooler that have a loose mounting, but since you might be into tech... might doubt that?

Have you used the system for a long time, and recent issue?

Hopefully, if you are using an AIO (watercooled) that your pump is working and not clogged if that may be an issue?

i think the cooler works fine because when i stress the cpu max temp is 62c. but when i turn it off i goes to 77c

*finds out your motherboard is screwed or an OC setting you used trying to fry your CPU with that POWWA*
anyways, don't know, hope someone else knows what it might be?
