Non scientific 100% amateur tests to satisfy my curiosity, take it with a grain or a bucket of salt...
Anyway, after +- 4 months I decided to check how the Krytox grease + Alseye T9+ Platinum mix was.
It not separate or dry and to remove the cooler from the CPU was easier, but 4 months is nothing...
Well, removed the mix and applied Zezzio ZT-GX that
feels and smells(clove/eugenol) like TXF.
Mixing +-20% of Krytox and the performance decrease +-+ 0.5ºC, but I am sure the lifespan is prolonged...
Removed the Zezzio ZT-GX and applied the Shin-Etsu 7921 which gave me an advantage of +- 1.5ºC over the Zezzio without Krytox.
I got lazy and didn't test 7921+Krytox, but will do for the GPU copper shin mod.
The Shin-Etsu 7921 is from AliExpress and seems not fake, I tested with paper to check for oil
or solvent and it had none like the original, considering the performance it must be original.
The Shin-Etsu 7921 is VERY dry/dense and not sticky, must heat it to be able to apply a paper thin
layer over the heatsink with a plastic card. I prefer to warm the heatsink(without fans) in the kitchen
stove(hot air from the fire), to make it hot/warm, but not burning hot.
Now I am mainly only using Shin-Etsu 7921 for CPU and for GPU the mix with Krytox to prolong the life span.
Shin-Etsu 7921 is old and still RuleZ!
High performance, not expensive, harder to apply, but because it is so dense it will not pump out easily and
that is why you should apply a paper thin layer with a small drop in the middle.
For those who don't know, Shin-Etsu is Japanese.

BTW, you may also find this post interesting...
this is not what i said. if you have a card that suffers a lot from it a tiny bit less tightened down screws leave a little bit more room and these ~0.2mm are enough on some heatsinks to make the whole pump out effect way less dramatic. my 2080 Ti had the worst issues where paste barely lasted...
