Thermal Grizzly from Hamburg is a German brand dedicated to combating high temperatures and poor heat transfer. The goal is to supply the overclocking community with high-performance thermal products, which still represent a weak point. However, the product portfolio can also be used for better and quieter cooling of gaming PCs, workstations, mini-PCs, and many other purposes. In addition to enabling higher clock rates, better thermal products allow for quieter cooling and a longer lifespan of the components being cooled.

The thermal paste named Kryonaut Extreme targets extreme overclockers with its outstanding thermal conductivity. As the name suggests, it is ideal for low-temperature cooling methods such as nitrogen or compressor cooling. Compared to Kryonaut thermal paste, the finer base particles of Kryonaut Extreme reduce the risk of cracks due to the high temperature differences in nitrogen cooling, thereby preserving thermal conductivity. Kryonaut Extreme is suitable for particularly low temperatures down to -250 degrees Celsius.

Embedded in a carrier structure are tin oxide components and particularly fine nano-alumina particles, which optimally compensate for unevenness on the surfaces of the heat source and heatsink while providing exceptional thermal conductivity. Additionally, Kryonaut Extreme is characterized by its ability to remain stable and not dry out even at high temperatures of 80 degrees Celsius, and it is not electrically conductive.

The Kryonaut Extreme thermal paste comes in a syringe with 2 g of content for approximately 6 applications—this, of course, depends on the amount used, the skill of the user, and the size of the CPU. The package also includes an applicator for precise application and distribution of the Thermal Grizzly Kryonaut Extreme.
