Anyone have experience with KryoSheet or PTM?

Dragonsyph · Nov 14, 2023

My system is a 13900ks OC 5.9 all core 6.2 3 core. Using LT720 AIO with Lian Li X fans.

I have been using Thermal Grizzly Kryonaut paste, and it keeps me below 90C during 100% loads.

My question is, are KyroSheets or PTM better than this paste? Will I see better temps or temp spread core to core?

Or is the only better option liquid metal or a delid?

I have tried to search for results showing temps but i have only found GPU or direct die comparisons.

5.9 all core under load.. under 90c on aio?What are ecores and hyperthreading off?

Ya, no HT, didn't see any FPS loss in gaming. Just using E cores as threads.

A long term LM user here who has swapped to PTM. It has been great for me and performance is similar to LM. No experience with Kryosheet.

Good to know, I might just have to try them out to see if it helps in my specific system. Was just trying to get a feel since they are like 28 dollars per sheet lol.

Yeah its a lot of money and difficult to apply.

I bought 2 kryosheets for both my 14900k and my 4090. I watched a video and it seems comparable to the Kryonaut , just 1-2c warmer so I don’t believe it’s going to be better in that term.

But it’s something that it won’t dry out and won’t pump out , it will keep performing just as good even after a year. With these high performance pastes you can already see the dry out effect just after 2-3 months.

Liquid Metal is top but it kinda bonds on the top layer of the cpu IHS and it’s like impossible to clean without removing also the lettering which makes selling the cpu way more difficult.

Therefore the KryoSheet is purely targeted for longterm , install and forget…

It’s definitely not suitable though if you bin CPUs or you are changing coolers as it should be used only 1 time.

I use PTM myself and would never go back to anything else, just make sure you buy it from the right places like moddiy and for me the easiest way to apply was toss it in the fridge/freezer for a few seconds, the film comes off easily without sticking to everything + while cold you can just cut it pretty easily with scissors while the protective film is on still

Got PTM on my 6900XT and the 5900X, destroyed the Kryonaut on the GPU, just slightly outperforms it on the CPU but comes with the plus that it will last forever without the need to reapply.
Application wasn't all that difficult even without putting it in the freezer.
Make sure to get the real thing (MODDIY) though, should you choose to give it a try.

Can somebody please explain how in God's name Honeywell's PTM 7950 or 7958 is supposed to outperform EVGA Kingpins KPx or Thermal Grizzly Kyonaut Extreme?

PTM 7950 & 7958 Thermal Conductivity Rating is 8.25 - 8.65 w/MK

Thermal Grizzly Kryonaut Extreme & Kingpin KPx is 14.25 w/MK

??????????????????????????????????????????????????????????????????????????

PTM7950 has replaced all paste and graphene for me. WAY better temps, no pumpout, no temp degradation.

Dragonsyph · Nov 16, 2023

Thanks all, think I will try it out. Love the whole idea of it too.

Thermal transfer (w/mk) of a material changes with the temperature of the material so you can't compare the specs between manufacturers unless you know they were each measured at the same temperature. Even then, the thermal conductivity to temperature curve will still be different between different material.

PTM is a phase changing pad that becomes a liquid at about 40*C. When it melts, I'm guessing the heat conductivity increases? At the very least, when it "melts" it will allow for a very good contact between the CPU and heatsink surfaces; basically creating a perfect and consistent application. Thermal pastes generally uses suspended particles which can impede surface contact between the CPU and heatsink which is the best/most ideal path for heat transfer (IMHO, this is why LM performs so well; it allows almost perfect surface contact).

Precisely. It's a lot more complicated than just comparing two numbers and thinking higher is better.

Don't know about that, but there is a direct heat dispersion comparison between using either Paste and these new Kyrosheets. The Kyrosheet will keep itself together far longer and maintain the heat dispersion better than any paste, sitting on any IHS. Also, no damage to the CPU at all, without any extra paste spilling downwards onto your motherboard

.

You will still have a functional CPU decades later or until Redmond releases another failed OS update.

Don't do that because the CPU might be used by someone else when you sell it off or give it away. Having the original IHS unmolested, is the better way of conducting decency to yourself and your future customer.

dudes about to learn marketing is all bull poop and companies routinely lie.

It's known as Public Relations. Routinely used by ALL humanowned-scumbag Companies and Politicians. WORLDWIDE - Extreme Fact.

What these products are for is usage and by whom. ALL companies want a permanent fix to their thermal transmission problems that hamper their business operations. The Kryosheet and PTM examples, are that.

Finally, a product that won't harden or flake away within a year or two. In fact, many businesses would keep their PCs for a decade or more. 10 to 20 years usage, no paste on Planet Earth would last that long - Basic Fact.
