Hmm... To my knowledge, the only paste that causes scratches was IC Diamond. I've used Kryonaut for years on everything from PCs, laptops, smartphones to consoles. Never had scratches in it.
Is it possible that your cooler already had paste on it from the factory and you overlooked it and mixed Kryonaut on top? Some coolers have that.
To answer the question. Yes, the paste is there to fill the scratches and imperfections. It should hardly be noticeable to you thermally, unless they are real canyon scratches.

No, that can't be. You don't have to pay postage when you pick it up.
It's best to call customer service, there's probably a mistake in the shop :)
Hi
I always use kitchen paper and isopropyl alcohol or rubbing alcohol. After cleaning, the remaining alcohol evaporates and no residue remains. A few drops on the paper should be enough.
Terve.
I have never used the Thermal Grizzly myself, but from the hardware (midrange APU + large cooler) I would say that it is not worth changing WLP. The AS 5 is a good WLP in itself and even if the temperatures should be slightly better, this does not make the processor faster. Even with an overclock, the performance increase is minimal.
Sayonara!
