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 put two 120mm fans on my shroud, pointed up at my 7900XT, set to spin at (whatever)rpm that I can just hear with everything else off, like it's there sound-wise but my dogs breathing is louder. The curve(on gpu) only gets aggressive when the temps clip 80c, and they just don't do that. I also kill the zero rpm setting in adrenaline, set them to just at the edge of my hearing and keep that setting until 80c on the gpu. Furmark WILL get the little guys going full tilt if I leave it on for awhile, I think the card heat sinks the entire enclosure. I don't see any game pushing the card that hard for that long tho.

I'm O/C'ed a little. 3000gpu and 2800memory(max limit, I let the card hound-dog it's happy place). I hardly reach mid 60s in timespy, hot spot will see mid-high 80s. Merc 7900XT.
