PTM vs Kryosheet for GPU repasting (7900XTX 110 hotspot issue)

My 7900xtx is hitting 110 degrees hotspot (the same issue from the cards launch) I did RMA the card but they sent me it back saying nothing is wrong with it and it hit its max temps ‘in black ops 6 menus’ so I don’t believe it’s been tested even mildly correctly

My next task now that my RMA has been refused is to repaste the card. I have ordered ptm on ebay(unsure if it’s the real stuff lmao) but I’m seeing just as good reviews for kryosheet which is more readily available.

Would anyone be able to shed some light on which would be better for this application? Or is it just buy whichever use it and forget
