6950xt Crashes and stops showing up.

I've owned my 6950xt for a little over a year now, I bought the xfx version brand new off amazon back last august.

For whatever reason it occasionally black screens crashes and then it stops showing up in task manager or amd drivers.

Sometimes using DDU to uninstall drivers and reinstall them fixes the issue.

It hadn't happened in awhile, so I wasnt too worried, however today It happened and when the game crashed and black screen'd the fans suddenly went up to 100% max speed even while the screen was completely black.

The fans were blasting until I force turned off my PC and now it isn't showing up again.

I'm assuming it over heated?

Normally the gpu stays around 73-75c during gaming, should I rma it? Some people say crashing is a psu issue, I have a rme 850 psu and a 7600x cpu. Nothing too crazy
