Picked up a phantom gaming 7900xtx open box from microcenter, booted up 3d mark timespy and immediately saw 110c hotspot temps, so pretty much instantly went to repasted, upon disassembly I noticed mismatched screws holding the back plate on, then once I actually go the card apart noticed it's missing the vrm thermal pads and all of the actual paste was squeezed out around the GPU.
Thought it was hilarious how bad someone diy'd repasting the card, it's getting returned on Friday when I get paid anyway for a brand new 9070xt, just wanted to share my interesting experience on this GPU that somehow passed microcenter "quality" checks.
