RTX 4090 Aorus Master w/ KryoSheet and Arctic TP-3

Changed the pads and put a KryoSheet in my 4090, here are my temps. Can anyone give me comparison valies? I feel like I am missing something here, I expected way lower temps.

Why did you expect lower temps ? Pretty much every review showed it performs about the same as good quality paste.

Well, I didn't expect lower temps per se but a tighter hotspot to average temp as well as lower mem temps. But I should've known that the factory setup was pretty solid, now I kinda regret doing it. I suspect a wrong assembly, even though I was extremely thorough. Dunno what to do, maybe I'll buy some putty and PTM9750.

Btw. one guy from a reddit thread I created has much lower temps with a much higher TDP:

You understand this can simply mean the previous application just wasn't that good, hence the difference, tests show there is no real advantage to hotspot temps, It's working as expected.

Btw the guy from your link says he used PTM7950, am I missing something ?

I don't think you can compare it to the XTX, as my cooler is completely overkill for the hardware, plus it's not as plagued with hotspot issues. I will see if I can reapply or maybe switch to PTM. What does concern me more are the RAM temps

Heat is heat, if kryosheet had better thermal transfer that would show up no matter what it was tested on, you can find tests on Nvidia cards as well. Kryosheet's selling point is lack of maintenance not thermal performance, PTM probably performs better on average as it can fill in uneven spots in a way that a solid sheet of material can never do.
