Alright, I ran Furmark for a while and didn't encounter any problems. Temp stayed at 75 and hotspot never went over 95.

While Reforger was working normally yes, sorry I could have been more specific.

I verified files as well as uninstalled and reinstalled the game, neither worked.

Could have been any of the driver updates since ~April, I tried the most recent drivers as well as a rollback and it didn't solve the issue.
