Bad temps (used to be amazing!)

GPU: Asrock Phantom 7900xtx Two different waterblock: Alphacool & bykski

Formerly Kryosheet never exceed 70c hotspot and normally gpu temps at max were 40-45c.

Since opening the block up a ton when flashing it for aqua XoC I noticed I can’t ever get good contact with the kryosheets… it always spikes to 110c. I can move over to PTM and temps never exceed limits usually around hotspot 90-94c which is drastically higher than before.

I noticed though these blemishes on the die which weren’t there in the past. I’ve rubbed my finger on them and feel nothing but no matter how much alcohol and rubbing I do I can’t remove them. I assume I could polish them out.

Could they be the culprit? I tested two different water blocks thinking maybe the old AC block was somehow the root issue…
