Thermal paste Thermal Grizzly Kryonaut Extreme

Thermal Grizzly Kryonaut Extreme is an extremely high-performance thermal grease designed for demanding cooling scenarios. With a thermal conductivity of 14.2 W/m·K and a density of 3.76 g/cm³, this 33.84 g (9 ml) paste is formulated with electrically non-conductive aluminium oxide nanoparticles to optimise heat transfer between components in both ambient and cryogenic environments.

Advantages

Kryonaut Extreme delivers enhanced thermal conductivity and stable performance across a wide temperature range from −250 °C to 350 °C. The inclusion of aluminium oxide nano particles ensures the paste remains electrically non-conductive while improving thermal interface efficiency, making it suitable for water cooling setups as well as extreme overclocking with liquid nitrogen.

Suitable for

• Extreme overclocking with liquid nitrogen (LN2)
• High-performance air and water cooling systems
• CPU and GPU thermal interface applications in enthusiast and professional builds

How to use

Clean both contact surfaces thoroughly and remove old thermal material. Apply a small, even amount of Kryonaut Extreme to the centre of the chip or heat spreader, then mount the cooler and allow pressure to spread the paste into a thin, uniform layer. For best results, ensure even mounting pressure and avoid over-application that could increase gap thickness between the surfaces.

Recommendations

Use Kryonaut Extreme when maximum thermal transfer is required, such as in extreme overclocking or high-performance cooling loops. Store the product at moderate temperatures and keep the cap closed to prevent drying. Avoid contact with electrical traces despite the paste being non-conductive, and follow standard safety and handling procedures for thermal compounds.
