Ptm7950 is a phase changing coolingpad/paste that turn liquid above 45C. It is used in industrial settings, on ledbulbs, but has recently become popular in notebooks and gpus. The Lenovo legion uses it aswell as Nvidia 4090 FE and perhaps other FE models aswell. It is a lot more expensive than most pastes and harder to apply, but longevity is supposedly many years. It also needs a many hours to perform at its best due to the melting process. I got a 40x80mm kit for 13usd on ebay.
My 4070 die is 15x20mm so I can do several applications with this. I put it in the freezer for 10mins, used a scissor to cut after measuring.
Application was somewhat tricky as it has a thin plastic film on both sides. Succeded after a few minutes.
I had reapplied Arctic MX-6 3 times after I got pump out the 2 first after using max mounting pressure. The stock temps where 59C core 83C hotspot. The last atempt with MX-6 was much better at 57-71C.
Then came ptm7950
Vs stock the result is amazing. 5C lower core, 11.5C delta vs 24C. Also a nice improvement
from MX-6 with 3C lower core and 5.5C lower delta
The temps started of worse at 55C and 67C delta, but got better after a few hours.
Overall very satisfied
Before you buy: This is not a good solution for everything. On direct die it performs best. On IHS it may not perform as good due to lower heat on parts of the IHS that may not reach the necessary 45C+. On goodwatercooling it will probably perform bad if temps never pass 45C. It is not easy to apply, but cooling it down before use helps a lot
