7900XTX Thermal pad size?

[TechPuppy]

Hello all! Am back! Have noticed temps getting somewhat higher than when I first got the card. They were in low 50s all the time with pl turned all the way up and now they usually sit around low 60s. While I know these temps are not an issue, they are about 10c hotter than when I first got the card about 3 months ago. What happens a year from now you know? I'd like to take care of them before they become an issue. Hotspot temp is usually 80c. Was wondering what the die size is, was thinking of getting one of those fancy thermal paste pads, the ptm7950 one to be exact, but I'm not sure what size to order or where to get a true Honeywell one cause I've seen some fakes going around as well. Also, what size is the normal pads that go on the memory and vrms and is there an upgrade I can buy for those that would help drop temps? Any help would be greatly appreciated!!

PTM can also dry out and be unstable. I would recommend kryosheet. Here on tpu was a good review and this comment is very helpful.
Each AIB will have its own gasket thickness, you will have to measure them or find a teardown review for your specific model, for example check the TPU database.

P.S. You have excellent chip and hotspot temperatures and I definitely don't recommend you to replace it at these temperatures. It's worth thinking about when the hotspot approaches 100°C.

Takes a good 10 years but yeah, any paste eventually does.

I used a 40mm square pad IIRC. Worked fine.

Get a set of metric gap gauges and messure the gap between the heatsink, die, ram, and vrms, then add .25- 1.0 mm to the gap for pressfit.

40mm x 40mm for your xtx? I'm sure every single die is the same but if it matters at all, my card specifically is the Merc310 Speedster one. I just want to have the pad here and ready that way my pc isn't down for a couple days because I ordered the wrong size lol

My card is the same model so good stuff. It's a bit too big but can be cut to size easily. You probably could get away with a 30mm square sheet but not certain about that.

This was my supplier, pricey shipping but absolutely genuine stuff:

I also redid the memory/vrm pads with some fujipoly pads but in my case they seemed fine and likely could've been given a pass.
