I have applied the PTM 7950 to several GPUs and laptop CPUs this past year. Compared to the other thermal paste that I have which is the CM Mastergel Pro V2, the PTM 7950 usually have around 4c better results. Application is fiddly though as there's 2 layers of plastic you need to remove on the material using tweezers or something similar.

I haven't used this on desktop CPUs though, they are expensive and desktop CPUs have much larger surface area.

EDIT :

Aside from the drop in temperatures, I also noticed the boost clocks are a bit higher as well especially on my laptop. YMMV depending on your specific designs.

- It's supposed to last for many years, and I have not noticed significant reductions in performance since application
- For the size, I bought the bigger one and then cut it to size
- Cut it as close as you can to the mounting surface size
- It doesn't drip to the side like more viscous thermal paste. When removed and not hot to the touch it looks like old hard thermal paste but that's just it's phase change nature.

In terms of viscosity when cold [more viscous to less viscous]
