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.

Yeh the XFX card has pads on vram and they ended up tearing so replaced them at 1mm which im pretty sure is right. Theres alot of pads on backplate and some other ones of various sizes that didn't tear. Long story short last time i opened card i was going to replace them all but hard to know how compresed they were and what size originally. The blue looking one looked like it was 2-3mm and was very soft didn't want to run into mounting pressure problems so just left them. Have ordered some u6 pro putty but as my temps ok not sure if ill use it straight away. I should really ask XFX Support for the sizes. Curious if putting 21W pads on backplate will help temps aswell.
