Yes. The thermalright odyssey pads were too stiff and not compressible enough on the 3090 FE (heatsink design problem--there are simply not enough screws to attach the PCB firmly to the heatsink, just the leaf spring and one screw by the PCIE slot thermal pad....and the screws at the very edge for the backplate...YIKES) so the contact pressure on the core was extremely weak (at this time there was no "Core hotspot" sensor in HWinfo64. With TFX I also noticed a rise in temps but it took longer to happen, and I noticed the core hotspot delta change from 11C to 16C in three weeks). Another user on the Nvidia subreddit noticed after a few months, his core to core hotspot delta was over 20C, so he ordered some Gelid pads also.
If the mounting pressure is bad, every paste is going to pump out. I don't mean DRY Out or separate, I mean pump out. That's basic high school physics. Heat expands, cold contracts. When mounting pressure is very weak, you get expansion+contraction, paste starts shifting around instead of staying in one spot. Combine this with a super convex Ampere GPU core, what do you think is going to happen? Magic? The bad pastes will separate into oil + dried useless whatever though.
I have a LOT of different amounts of thermal paste, and still over 100 grams of Liquid Metal (Galinstan).
Now that I switched to Gelid Extreme pads, the delta (core to core hotspot) has only changed about 0.5C in 2 and a half weeks, which is a hell of a lot better than 5C.
I have not seen any problem with Kryonaut Extreme on my desktop CPU's or my radeon r9 290X. Testing it now on my MXM GTX 1070 now.

Kryonaut Extreme vs TFX is strange.
Seems that Kryonaut Extreme needs good mounting pressure since it's not as thick.
Kryonaut Extreme vs TFX:
Radeon R9 290X: 81C vs 83C (80% fan speed, Valley benchmark, bad ambients (section 8 apartment, sorry, don't expect much)
Kryonaut Extreme 2C better than TFX (mounting pressure seems really flat)
Geforce GTX 1070 MXM (laptop), Heaven benchmark. TDP modded @ 230W
72C vs 71C (TFX 1C better).
Arctic MX-5 is 73C.
I guess that goes in line with this laptop results chart.
