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.

im actually afraid to buy the aliexpress "ptm", its most likely fake because its by far the cheapest option (vs Amazon or original PTM)

(vs Amazon or original PTM)

heres the secret , on amazon its just dropshipping or someone that bought it via Ali / alibaba and throwing a hefty margin on it.

A lot of people ordered from there, including me and nobody complaints. Just take the most popular one(filter by orders), but i doubt there's fake's at all.

I just rewatched that Linus video yeh the piece i got from AliExpress definately didn't have rough edges or air bubbles or damaged edges like the one they showed looked like the more expensive one they showed. I guess mine came in bubble wrap and envelope and was lucky during shipping i think Moddiy put it in a cardboard box. At the end of the day it melts at 45C so good either way.
