Just wondering how much thermal putty might be needed for a 7900xtx, my model being the:

NITRO+ AMD Radeon™ RX 7900 XTX Vapor-X 24GB.

I'll be adding a water block to it later

The thermal pads between the block and core are all 1mm, and the pads between the PCB and backplate are 3mm.

If anyone understands the math of thermal putty to pads, here are the pads the water block comes with.

I've been reading and looking at Snarks Corner for some education on the subject, but I'm hoping someone here has first-hand experience with the card.

I was thinking the 50gr tub of Upsiren Ultra + another 20gr.
