Thanks to all the enthusiast, I am looking determined to make my GPU cooler.

I have not received my 9070xt yet, but when I do, I'd like to know if I can cool the backplate by putting these fins

I've got pretty good airflow (excellent, actually) and would like to learn from the gurus if its been done on this particular model.

Maybe I'm being too pre-emptive, but I have seen some vrm temperatures during tests that go up to 90+ degrees. I know its still safe, but would be better cooler.

Yes I might be able to undervolt it, but I want to try and see if I can cool it without taking the card apart or unscrewing anything.
