Thermal Grizzly Kryonaut Extreme thermal grease has thermal conductivity of 14.2 W/mk
Typically when you use thermal grease W/mk it sits at 6W/mk if you have a good brand. Thermal Grizzly's ultra-high performance thermal paste "Kryonaut Extreme", boasts an extremely high thermal conductivity of 14.2 W/mk.
The Kryonaut Extreme thermal paste is aimed at extreme overclockers with its outstanding thermal conductivity . As its name suggests, it is ideal for low-temperature cooling such as nitrogen or compressor cooling. Compared to the Kryonaut thermal paste, the finer base particles of the Kryonaut Extreme ensure that there is less risk that the high temperature differences will result in nitrogen cooling"cracking" occurs and thermal conductivity is impaired. The Kryonaut Extreme is suitable for extremely low temperatures down to -250 ° C.
Tin oxide components and particularly fine nano-aluminum oxide particles are embedded in a carrier structure, which optimally compensate for unevenness on the surfaces of the heat source and heat sink and at the same time offer outstanding thermal conductivity . The Kryonaut Extreme is also characterized by the fact that it does not dry out even at a high temperature of 80 ° C and is not electrically conductive.
Kryonaut Extreme thermal paste comes with 9 milliliters content for about 90 applications - this of course depends on the amount used and the skill of the user and the size of the CPU. The scope of delivery also includes three applicators for the precise application of the Thermal Grizzly Kryonaut Extreme .
Please note the manufacturer's warnings before use!
Technical details:
- Quantity: 9 ml / 33.84 g
- Thermal conductivity: 14.2 W / (m · K)
- Density: 3.76 g / cm³
- Viscosity: 135 - 180 Pa · s
- Operating temperature: -250 ° C to 350 ° C
A bottle of 9ml will cost you €89,95, there's also a 2g version at 20 bucks.

As the the name and description says, it's mostly intended for extreme overclocking (sub-zero), due to stability at very low temperatures ...
... not a product for everyday usage.
I have the "normal" Kryonaut on both my CPU and my GPU and it's working as intended, shaved a few degrees in load temp from the stock paste. Is that much difference ? Not really... but if possible, why not ?

You answered your own question there ...
The 2g version comes in a syringe though.

Shall try some of this next time I get ln2, so far preferring KPx over Kryo, maybe this new paste from Roman will convert me back to Grizzly

Not sure why the pictures show the syringe applicator. The 9mL version actually comes in a jar with three spatulas. See the TG product page or the Australian PC Case Gear reseller's page. The 2g version comes in a syringe though.
Also, 14.2 W/mK for the Extreme versus the 12.5 W/mK for the "normal" Kryonaut... Wonder how much difference that actually makes?
I can report a nice temperature drop on my friend's RX470 GPU. Since it was brand new under OC it gave out max temp around 74 degrees C. After changing the paste to Kryonaut with max OC under stress test the temps don't go over 66-67 C.
On the other side, when applied to a normal CPU there is maybe a 2-3 degree C difference and i am using it with my AIO. The thing i love the most is no need to change it since it is incredibly stable and there is no curing time...from the moment you put it on it gives max performance immediately.
To sum it up...amazing results when used in direct die contact applications such as GPUs, laptops, delidded CPU or anything alike, and above average performance when used on a regular CPU with an IHS.
All in all an amazing product!
