I'm using a Kryosheet

[no_1_dave]

Thought I would try one on my 13900k

Fitting it is easy but frustrating. It slides very easily so when putting the cooler on if I moved the cooler sideways slightly I got scared and had to take the cooler back off to make sure the sheet hadn't moved. Sometimes it had and sometimes it hadn't so was really hit & miss. Ended up giving up and just hoping it wouldn't move. I don't think it did because on my final attempt I don't recall any movement from the cooler, but there is no way to tell so just hoping. In this regard paste is better, but I pressed on all the same. I'm using a Thermalright contact frame instead of the stock Intel CPU holder so as far as I am aware there is no worry about the kryosheet's conductivity as it won't be able to reach down to any components.

Previously I was using Kryonaut and I'm noticing a difference of about 7c-8c when I'm stressing my CPU to the max for a long period of time (video encoding). I checked my CPU temps after 4hrs and 13hrs of full 100% load and the temps were not even in the 80s. When using Kryonaut my temps were hitting up to 87c. It'll be interesting to see if the temps raise over time or if the claim that the kryosheet doesn't wear out are true. So far I'm impressed

Is anyone else using one?

No, but I would rather use the new Gelid HeatPhase Ultra or PTM-7950 or UPSIREN PCM-1.

Any reason?

I see they're cheaper which if they perform equally would be a good enough reason but I don't see any comparisons...

So your saying the Kryosheet is 7-8c cooler than Kryonaut? Thats interesting because all reviews I've seen have placed the Kryosheet atleast a few degrees behind Kryonaut. How long ago was the Kryonaut installed?

Since a few weeks after the 13900k was released.
My 13900k has always gone into the mid-high 80s while encoding and this is the first time it hasn't
