I also tried PTM7950 on my TUF 4090.
After one week, I would say the core temperature didn't drop compared to high quality pastes, but the hotspot did. And it seems to only get better over time rather than get worse which it did with 3 high quality pastes that I tried. 
Highly recommended.

It will take some time to see the full results, I went from 28-32c idle to 72c at full load with cyberpunk fully maxed out with the hot spot hitting 82c and that was with an aggressive fan curve. This is after a year of ownership as things slowly heated up.

With the pad installed and cured. Went down to 25c idle, a max temp of 57c and the hot spot not exceeding 67.1c. Once I yeeted my overclocks as you see above the Honeywell PTM7950 pad cured rather quickly and temps got better all around. 

New month. So here is the update on my temps...
 
Temps are still doing great.

Good to hear.  I'm hoping to repaste my year old EKWB install in the next couple weeks.  I just got back from a long vacation and didn't get to it yet.  I was going to try KPX on it, had already bought before you guys were talking about the other one.  Will be interesting to see how it compares to the Kryonaut I put on there the first time.  Probably going to do my CPU with it while I'm in there as well (2+ year old Kryonaut on that as well).

If you opened your RTX 4090 to re-paste it you might have voided the warranty. 

lol. I’d like for them to try it. I’ll contact the federal trade commission, and file a case in small claims court.

lmao..im sure that would have worked out for u

How do you guys cut these pads to down to size of the gpu and cpu? I am gonna redo 2 of my watercooled computer systems next weekend.

Sharp scissors worked for me.
