PTM7950 Thermal Pad Phase Change Heatsink 80x80x0.25mm 8.5W/mK Conductive for Heatsink PS5 Steam Deck CPU GPU SSD Silicone Grease Thermal Pad

Does not make any difference - temp went up 5C Sent back - Suspect this is a FAKE product looking at the way its cut Waste of money

Dropped the temperature on my steam deck by 6-7 degrees, much better than i was expecting.

Was not 80mm x 80mm piece. It was a used piece with rectangular pieces cut out.

omen 13900hx ve 4090a uyguladım Sıcaklıklar daha da kötü oldu Ya orijinal değil ya da tam olarak istenilen performans a ulaşmıyor

This may or may not be genuine Honeywell PTM7950, and that is okay. It performs great, working better than liquid metal on my GPU for keeping average temps closer to hotspots. It will probably shave a couple of degrees off of standard thermal paste, but the really good thing about PTM7950 is that it doesn’t pump out like thermal paste. Once you apply, it’s done for years upon years. It was kinda hard to apply only because I didn’t freeze it before use, but it would be easy if I had frozen it. Cutting to size, peeling one side, then applying that side to the die worked best for me. Some helpful tips for PTM 7950: 1) it will not be perfect at first. PTM7950 has to “burn in”. What this means is that you need to heat up the GPU or cpu or whatever you applied it to. Hours upon hours of stress tests/just gaming to push the card will get this to work. What PTM7950 does is turn liquid at higher temps, so once it changes to liquid, it will fill in the gaps and help thermal performance. Burning it in helps with this 2) freeze it for 30 min before applying. This stuff is soft, very soft, so peeling off the plastic film is hard if it’s room temp because it is very malleable. If you mess up, just heat it up (a lot, more than 50C) to fix any issues. 3) it needs to be a good size. What I did was measure my die size with calipers, then cut 0.5mm larger. If I got 20 mm, I cut to 20.5 mm. This helped with application, giving me just a bit of wiggle room. Do not do any larger, as it should be almost a perfect fit to the die. So yeah, this stuff does work as advertised. Whether it’s genuine or not, I don’t care. It worked great for a full size GPU, and the cpu and GPU of my laptop too. I am very happy with it.

Llegó a CDMX en 3 días, se aplicó como reemplazo a la pasta térmica que viene de fábrica en la Steam Deck. Como mencionan en otros comentarios, ponerla en el congelador 5 minutos antes de aplicarla ayuda bastante.

I used it after using liquid metal. At first I thought it is bad because the temps were very high... But the longer stressed the processor, the better the temps became... After one week, it became as good as liquidation metal with the exception of being more safer to apply....
