Standard Kryo is a bitch for pump out, how is this one?
I can't find any reviews at the moment, which is kind of annoying. Being thicker that stand K I hope for less pump. I was also wondering how it fairs at temps, because standard kryo again suggests it can handle anything yet bitches out at 80c and then starts being rubbish.

I know it's expensive I know it's only a few degrees (if any) but that isn't a concern, I just want to know how it performs if anyone can answer that?

Please and thanks!
 
I haven't had a chance to actually benchmark mine but I used it to apply a gpu cooler last week. This stuff is thick, and relatively hard to spread compared to the normal.
I'll be actually building next week so I can see how it goes with a 12900K + 3080ti in a custom loop.

How did you find it in the end?

probably pish like the standard stuff

It's supposed to be the best stuff out, why do you say it's 'pish'? (I don't necessarily disagree with you!)
 
I use Kryonaut on my GPU, CPU and motherboard chipset and have never had any problems with it at all. For my setup it's consistantly 2-4 degrees better than any other thermal paste I have used (MX-2, MX-4, Gelid Extreme and others). I find it's best to warm it up before use to make it easier to spread.

Really? With Shin-Etsu I'd agree but my tube was quite gooey and easy to spread. They're all grey, right?

Whilst I have nothing to compare it to, my 12900K running at stock hit a maximum of 88c in Cinebench R23 after 10 minutes. Ambient temps were around 25-26c, and this was in a custom loop using a Velocity block from EK.

Central heating or hot country?

is there any benefits using liquid metal on air coolers, for example an air cooled GPU?

Thermal Grizzly Kryonaut/Kryonaut Extreme is not liquid metal.

As to your 2nd question there will be a benefit to using liquid metal TIM on any cooler be that air or otherwise, but one needs to be aware of the slight drawbacks like permanent discolouration.

As far as I know they are all grey. I only have experience with Aquanaut and Kryonaut but Kryonaut is much thicker and harder to spread than Aquanaut which itself is thicker and harder to spread than Aeronaut. We had a big thread about TG when it first came out and people were complaining that it was too difficult to spread and someone came up with the idea of warming it up before use. If the heating is on when I am going to use it I put it on top of one of the radiators for 10-15 minutes. If the heating is off I stick some hot water in a mug, put the TG in a bag and place it in the water for 10 minutes or so. It makes it much more user friendly. I certainly won't be using anything else until something better comes along.
 
From what I read last night, the Extreme is the only one that is pink.

"Thermal Grizzly Kryonaut Extreme is an extremely high performance thermal grease, which shows it’s true capabilities in cryogenic enviroments such as extreme overclocking with liquid nitrogen. Addtional electrically non-conductive aluminiumoxide nano particles and improved application evolved Kryonaut Extreme to our new high-end product. In cooperation with leading engineers and pro-overclockers Thermal Grizzly made sure Kryonaut Extreme works in ambient application such as water cooling as well as with extreme overclocking such as liquid nitrogen."


EK supplies Thermal Grizzly with their waterblocks but it doesn't say which. It only says Thermal Grizzly on the tiny tube but when I used it, it was quite soft but gooey. I also have Kryonaut sealed in quite a long tube that was never used yet.

I'm wondering if EK supplies Hydronaut...

"The Hydronaut thermal grease delivers optimal heat transfer capabilities for larger-scale cooling solutions like water cooling systems.

Hydronaut thermal grease consists of a silicon-free structure. The makes it very light and highly flexible and easy to apply."


From 4 years ago... "I can't say for XSPC but the included paste for EK blocks is thermal grizzly hydronaut and you should very much use it."

4-5C warmer on GPU and CPU with it.

It comes in 2nd place.

Hmm... Arctic Silver comes in 1st place?...

Guru3D also recommends Thermal Grizzly.

Conductonaut is the liquid metal.

I've been using regular Kryonaut for ages after it was recommended about 5 years ago... Now everyone is saying not to use it without heavy overclocking and it loses effectiveness quickly?

Is the tech industry just fickle or is it really not as great to use longer term? I used it on my GPU and trying to decide if I should regret it or not
 
I have to say I tend to agree with @Ross Thomson. When I tried Kryonaut I was a little disappointed as it was no better than the MX4 I had at the time. MX4 was ~1.5c better when tested twice, which is margin of error but still wasn't better.

I've just recently tested (using Unigine Superposition looped for 30min) MX4 (2019) against Noctua H2 on my RTX 3090 and the H2 was ~3.5 better - 73.1c vs 76.6c.

So I'll use Noctua H2 over Kryonaut which just seems overpriced for what it is.

been using Kryonaut for years mainly because in every review its always near the top but yeah there isnt that much difference to the others , its pricey but it lasts me years I dont often upgrade :) last build I had it on for over 1 year didnt notice any degradation in temps from the day it was applied, current build is 10 months in
