I peeled off like a good amount of the thermal pad on one of the memory modules and was paranoid that it won't get good contact, but regardless I tried to heat it up and it came off easy followed with some IPA to clean off residue. The idea of leaving it and have it smush together was what I thought in the first place but I didn't want to risk anything and ruin my gpu. I'm going to apply the new thermal pad and see how it goes with that
