Thermal Grizzly Kryonaut extreme
For overclocking without compromise
Kryonaut extreme was developed to meet the highest demands in extreme overclocking. With ultra-fine particles and optimized layer thickness, the paste maximizes thermal conductivity, making it perfect for setups using liquid nitrogen or water cooling systems.
Available in two sizes: 2g | 9ml
Optimal thermal conductivity even under extreme conditions
With added nano-aluminum oxide particles, Kryonaut Extreme fills even the smallest irregularities to effectively dissipate heat. It remains stable and does not cure even at extreme temperatures, ensuring your system stays safely and powerfully cooled at all times.
Application Tools
Kryonaut Extreme 2g comes with two applicators to simplify the application of the thermal paste.
Application of Thermal Grizzly Thermal Paste
Apply a small amount of thermal paste to the CPU
The surface should be thoroughly cleaned and free of grease before use. We recommend using TG Remove or TG Cleaning Wipes for cleaning. The thermal paste should be at least at room temperature when applied.
Spread the thermal paste
When applying, it is important to spread the thermal paste very slowly. For a typical Intel or AMD CPU, a single spreading motion should take about 3 seconds. The slower the movement, the easier it is to spread the paste evenly.

TLDR, Don’t buy if you are using 9800X3D unless you want something pink.It is expensive. You don’t need LN cooling feature. It is hard to apply properly, and might pump out quickly if you have large and frequent thermal cycle. And most of all zero temperature (or less than 1C) improvement compared to MX6 for 9800X3d. So save your money if you have 9800x3d and get any of like MX-6 and equivalent. They won’t make huge difference. And they are way easier to work with.My idle are from 43C to 43C after switching from MX6 to Kryonaut Extreme and 74C max to 74C max for 100% load (~75% fan) at cinebench 2024 (PBO negative 35 all cores and auto scaling) with PA120 (1 fan only in middle, I tested with duo fan setup and see no noticeable temp change here).It works for chips which are themal paste bottlenecked. But in the case of 9800x3d, you are actually not limited by thermal paste. So it won’t make any noticeable difference. On contrary, it is much more difficult to work with and spread since it tends to stick to spatula. And also it is known to suffer from durability issue if you have frequent and large thermal cycle. And you really don’t need the feature for LN cooling. Ofc, it is more expensive. If you want something pink, you can get it, otherwise a cheap and decent thermal paste will serve you well for 9800x3d.

After using arctic silver for over a decade and hearing they’ve gone downhill I wanted to try one of the best, and this paste doesn’t disappoint, easy convenient applicator and perfect temps on my brand new 9800x3d.

Thermal Grizzly Kryonaut Extreme takes the already perfect and beloved normal Kryonaut paste and takes it up a notch, by creating that new notch for itself. While many may not see the need to find the “best of the best” in every product they buy, and while I don’t necessarily either in every area of commerce, PC parts and accessories are something I’ve spent over a decade testing, perfecting, and tweaking to gain the highest performance possible.Kryonaut Extreme is not your average consumer thermal paste, nor is it just a “top shelf” product. It’s in a category of its own, and consistently beats out competitors in every aspect time and time again. You can look this up yourself, or take it from me (a stranger ranting about their niche interests on the internet), Kryonaut & Kryonaut Extreme consistently deliver the best cooling possible, the lowest CPU temps, and the best durability on the market for ultra high performance thermal pastes. It’s easy to use, comes with a spreader, and 2g is more than enough for a single application, and I currently use the 2g size every 6 months to 1 year to make sure I’m always on top of my game (highly unnecessary, this paste will last you 2-4 years at a normal or above average usecase, I just push my overclocking to the absolute max.)While it’s designed to be effective with LN2 cooling, it’s more than effective for every PC user putting any stress on their CPU, regardless of how they’re cooling it. It’s well worth the price for the size, and you will not be disappointed in any way with Kryonaut Extreme.

For the price, it's worthy. I used it and the result was great.

Super impressive thermal paste, after finding out MSI has horrible thermal paste I decided to repaste after 4 years. The before and after is while gaming, my CPU would sit at 50C idle and is now 40C idle. I also had enough paste for my GPU which knocked down from 44C idle to 35C. For the price this paste is definitely worth it.

I bought a new laptop and the temps would stay around 85 to 95 during normal tasks. This thermal paste brought down the idle temps to the 40's. I am very pleased.

this stuff is THICK and a pain to manage. actually wasted a good bit trying to get it spread and not so thick at the same time.but I can't argue results. with this and the Arctic LF III 420 AIO, my temps are crazy low even with cinebench testing my highest temp was 75 with fans still pretty quiet

Troquei os termal pads (Pad Térmico Pcyes Nitrogen Pad Extreme, 100 X 50 X 1.0mm) e pasta térmico do PS4, o mesmo esquenta mas não ativa o cooler de refrigeração em potência máxima. Sensacional!

It always amazes me how just changing pastes can affect your temps so much. Anyway...This stuff works great, I dropped temps by 8 to 10. I don't like how it spreads compared to arctic mx-4, but if you're just looking for results, this stuff will do the job well. I got about 5 years out of an application on a *heavily* overclocked ryzen 3400g before I checked it, and it probably could have gone for longer.Short version: if you don't mind fighting with thick thermal paste, this is the stuff you want. If 8c won't break you and you're lazy, stick with the MX-4.
