Which Thermal compound should I use?

[jdamp]

My 5090 CORE block just showed. I have a few different thermal pastes laying around and wondering which I should use.
1. TG: Kryonaut
2. Liquid Metal
3. Alpha Cool that came with the CORE.

Is there any issues using Liquid Metal on the CORE? Maybe not the best because of the size making contact more difficult. I'm leaning towards the Kryonaut

We naturally recommend using our thermal paste, as we consider it to be the best option.
Liquid metal does offer even better performance, but it also comes with certain risks. If any of it gets onto the surrounding contacts during installation, the GPU can be permanently damaged.

The performance gains achieved with liquid metal are relatively small compared to the potential risk. Additionally, both the GPU surface and the cooler base may suffer — you’ll likely see visible marks if you try to clean it off later.

Kingpin KPx is another choice. From what I have read. It is better than Kryonaut by a couple degrees. I will be using it once my system is back together.

Oh right. I'll have to get some KPx. this is just what I had on hand. I put the Kryonaut on for now. maybe upgrade later once I figure out how I'm getting the card to fit in my case.

KPx is only a couple degrees cooler. If there is Kryonaut on hand. I'd say use it. All I had was Arctic Silver 5. Needed to upgrade. Only reason why I got the KPx. Good luck shoehorning the 5090 in!

gpu dies are so large using liquid metal its going after 1c-2c at most its not like a die on a cpu where the surface area is small and you need every bit of thermal transfer you can get. use the included paste or kph kryonought
