In the majority of overheating cases.. it's actually the power supply at fault.

It's awfully suspicious that the symptoms have been mentioned elsewhere. I'm not drinking the coolaid, I only mentioned that as an easy google result. A power supply is way cheaper to replace than a card these days, I checked that first before the system would no longer boot. I then swapped out some components reseated everything except the cpu and even tried the gpu in a separate machine with different games and then valheim. It's true I could be incredibly unlucky having both cards begin to fail at the same time, but I can't explain it otherwise, and it's worth looking into.
