It's exactly that. GDDR6X cards have to have the thermal pads replaced or they can't mine at reasonable speeds without burning out. With a proper replacement it will run at a very good temp (and actually games at much lower temp than it would without).
You can force a miner to send you a screenshot of the card with a 10 minute OCCT VRAM test if you want to confirm there's no VRAM issues from it being mined on.
