About this item
- The Kryonaut Extreme christened thermal paste is aimed at extreme overclockers with its outstanding thermal conductivity
- Compared to Kryonaut thermal paste, the finer base particles of Kryonaut Extreme ensure a lower risk of "cracking" and impaired thermal conductivity due to the high temperature differences in nitrogen cooling.
- The Kryonaut Extreme is suitable for particularly low temperatures down to -250 °C.
- In addition, the Kryonaut Extreme is characterized by the fact that it does not dry out even at a high temperature of 80 °C and is not electrically conductive.
- The Kryonaut Extreme thermal paste comes here as a syringe with 2 g content for about 6 applications.

Product Description

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.
-
My thermal paste is difficult to spread or comes off the surface. What can I do?
The surface should be thoroughly cleaned and be free of grease before use. The thermal paste should be at least at room temperature when applied. It is important to spread the thermal paste very slowly during application.
-
How long is Thermal Grizzly thermal paste usable after opening?
With proper storage and packaging, the thermal paste can be used for at least 3 years without issues, and in many cases, significantly longer.
-
Why can't I find the thermal conductivity value on the packaging?
The typically theoretical thermal conductivity values vary greatly depending on the application, as important factors such as contact pressure, temperature, or surface cannot be uniformly accounted for.
-
Should I store the thermal paste in its original packaging after use?
Thermal Grizzly thermal paste packaging is specially coated on the inside to protect the syringe and its contents from UV radiation and other environmental influences. We recommend storing it in the original packaging.
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.

- Reviewed in Canada on March 24, 2024Verified PurchaseCorrect me if I'm wrong, but I haven't found a paste with a higher heat conduction than liquid metal on the market! Excellent paste, easy to apply, great durability and definitely overclock ready! I've built PCs for different companies and only use this paste for the most reliable heat conduction!

- Reviewed in Canada on February 11, 2023Verified PurchaseAre you a hot gamer? Is your rig emulating your radiant personality and lighting itself ablaze like a phoenix of cheap ass budget parts? Put this on your CPU and GPU and from the ashes will arise the gateway to the world of the PC MasterRace. This paste keeps even the hottest rigs running like made of dry ice.
Clearly that was a joke but its good paste. if you are looking for something to optimize your next build this will always be a good option.
- Reviewed in Canada on June 22, 2023Verified PurchaseOne of the best performing thermal pastes if used in the right setting.
This paste can provide the best thermal performance if not used in super high sustained temperatures (+60c) due to its ability to pump out over time.
Would not recommend this for GPU or laptop re-pasting applications.
- Reviewed in Canada on October 29, 2022Verified PurchaseUpdate 4/29/2024: Ordered a second tube, and authenticator confirmed legitimate once again. Happy with it's performance. I now use it for the CPU + GPU blocks for my fully water-cooled system.
Ordered a 2g tube to replace my old tube of Arctic MX-4 and the last bit of Thermal Grizzly paste that came with my Ekwb CPU block. So far, initial performance is good, but will update the review again at a later date.
I was a bit skeptical due to the all the possibly fraud/fake Thermal Grizzly paste reported online, but the official authenticator confirmed the Kryonaut Extreme I received PASSED on their checker.

5.0 out of 5 stars Tercih edilebilir.
Verified Purchasei9 13900HX ve i5 8300H işlemcilerde kullandık. Laptop için alacaksanız bilgisayar genel soğutma bloğunun ve fanların tasarımı kesinlikle kullandığını termal macundan daha önemli, o yüzden taze sürülmüş başka orta düzey bir termal macundan çok çok farklı bir sonuç vermeyebilir ama muhtemelen masaüstü bilgisayarlarda çok işe yarayacaktır.
