Thought I’d post my experience on using Ali Express PTM7950 and Upsiren 1mm 21W Thermal Pads on Vram. Before PTM7950 with stock paste the gpu would be at 2814MHZ GPU and 2514MHZ Memory and Hotspot would max out at about 90-93C running Time Spy Default.

After at 2914MHZ GPU and 2700MHZ Memory with 24C Ambient at 3 Days i get 78.7C Hotspot running default Time Spy. Since then its dropped a little bit more with a screw tightening. I bought the 80x80 as it took a couple tries to get it right but think it would be easier next time. Definately put in fridge for an hour 1st as its like peeling off one of those kids tatoo transfers very thin.

    I got 31.5K with my 7900XT Taichi :) Fully stable too.

    BUT I’ve started to notice the hotspot creeping from 75c with this overclock profike, to 100c slowly over the past few months. Has to be pump-out… It’s even getting colder (ambient).

    Where can I get some PTM 7950 in Europe? I found a tub once but it was like €500 lol.

    I also have a tube of Gelid paste that’s supposed to be really good against pump-out because it can handle slightly higher temps (around 80c is where most pastes start to detoriate) but if PTM is affordable, might as well go that way. Memory is fine but a 60c core and 100c hotspot is not.
