About Kryonaut Thermal Paste
Kryonaut thermal paste was developed specifically for extremely demanding applications and the highest demands of the overlocking community. It is also recommended as a top product for critical cooling systems in the industrial sector.
Technical details
- Viscosity: 130-170 Pa⋅s
- Density: 3,7g/cm3
- Thermal Resistance: 0,0032 K/W
- Electrical Conductivity: 0 pS/m
- Application Temperature: -250 °C / +350 °C
- Capacity: 1g | 1,5ml/5,55g | 3ml/11,1g | 10ml/37g
Characteristics
- designed for Overclocking
- excellent thermal conductivity
- long-lasting durability
- no curing
- no electrical conductivity
Structure is the secret
Kryonaut uses a special structure, which halts the drying out process at temperatures of up to 80° Celsius. This carrier structure ensures that the nano-aluminum and zinc oxide components of the paste bond optimally, to compensate for unevenness of the component (i.e. the CPU) or the heat sink, thus achieving remarkable heat transfer.
Great compatibility
Compatible with almost all cooling solutions, including air, water, and even liquid nitrogen (up to -250°C).
Compatibilities
- PS3, PS4, PS5
- Xbox 360, One, Series S, Series X
- CPU, GPU, LEDs
- Heat dissipation fins and fan
- Laptops, Macbooks
For the true Kryonauts amongst the extreme Overclockers
„Kryo" - the greek word for "cold" - also found in the german word for "cryoengineering", suggests that this thermal paste was created especially for cryogenic applications - for the true "Kryonauts" amongst the "extreme overclockers".

Funktioniert echt super. Lässt sich leicht dosieren und auftragen. Super Kühlleistung in Verbindung mit einer AiO.

Dropped temps by over 5 degrees on many systems I tested on. multiple AM4 setups, couple 2011-3 setups, and 3 OG xbox's were restored to normal temps. The xbox's had original paste, and not comparable.Old paste on computers was artic MX-4, had full coverage, and were re-pasted purely to test.Be sure to only note your temps AFTER heat cycling a few times to let the thermal paste fully bed into place.Initial temps will almost always be higher than the settled temp later on.

There was actually a noticeable change in temps after using. Running the same games for the same duration and the temps ran about 6 degrees Fahrenheit lower than before using grizzly.

That is an excellent stuff! I tested with old Intel i7-3700 using its stock cooler (with copper core).With BurnInTest 8.1 (all temperature in Celsius degrees):Arctic Silver: 80Arctic MX-3: 80Grizzly Kryonaut: 78During the normal computer use:Arctic Silver/MX-3: 58-65Grizzly Kryonaut: 48-54Highly recommended!

Reduced my Omen laptop temperatures from 90s to 80s now.Though be ware that this paste dries up fast with heavy use so you may need to reapply after a year.

One of the best general-use thermal pastes I've used in the last 30 years.

Long service life for a paste, not electrically conductive, high efficiency I notice a BIG difference from Arctic Silver 5, solid value for the price, works great on my Xbox One, worked great for a number of AMD and Intel laptops and desktops. There are better pastes for certain use cases, there are better value pastes with less performance, there are thermal pads that are more permanent and perform better for a hefty price, but for the average use case this is phenomenal and 5.55 grams lasts a while. 10/10 product.

I have been using it for years and it does the job. I had to repaste my PS3 and PS4 and it was slightly dried out after 4+ years. Still no issue with its performance. This my go to paste and I build and refurbish many systems. Use the paste the overclockers use

I used this on my 5900x. It keeps the temps lower than the Tuniq paste I'm used to using. Also you really have to push to get the applicator tips installed onto the tube. They are the correct size, it just takes some effort to connect them.

Used it for my PS3 after almost 10 years of not changing the original thermal paste because I forgot. Seems to be working fine and I could notice the it was working better and not running too hot. Gives your PS3 a new life and hopefully will make it last longer. Good replacement and the product looked really nice when applied.

Świetny produkt, bardzo łatwa aplikacja. Niestety jeśli masz procesor 12 generacji lub nowszy 1g tej pasty to już za mało.

J'ai remplacé de l'ARCTIC MX-4 par de la MX-6 sans réel gain de température. J'ai donc opté cette fois pour de la Cryonaute et j'ai gagné au moins 3-4 degrés. A pleine charge, le processeurs oscillait entre 70 et 72 degrés °C avec l'ARCTIC. Maintenant, la température ne dépasse pas les 69-70°C sous Prime95.
