Thermal Compound Thermal Grizzly Kryonaut

Thermal Grizzly Kryonaut is a high-performance silicone-based thermal compound designed for demanding cooling applications such as CPU and GPU heat transfer. With a thermal conductivity of 12.5 W/m·K and a density of 3.7 g/cm³, Kryonaut provides stable thermal interface performance and long-term durability. The paste is supplied in a 3 ml syringe (weight 11.1 g) and is intended for users who require reliable heat dissipation without electrical conductivity.

Advantages

Kryonaut is formulated for overclocking and critical cooling systems, offering excellent thermal conductivity and a structure that prevents drying out at temperatures up to 80° C. The compound contains nano-sized aluminum and zinc oxide particles that improve contact with uneven surfaces of CPUs and heatsinks. It does not cure and is electrically non-conductive, making it safe for sensitive components.

Suitable for

• CPU and GPU thermal interface material
• High-performance desktop overclocking
• Critical industrial cooling systems requiring non-conductive paste
• Applications needing long-term thermal stability

Key specifications

• Brand: Thermal Grizzly
• Model: Kryonaut (MPN TG-K-030-R, EAN 753677507210)
• Thermal conductivity: 12.5 W/m·K
• Density: 3.7 g/cm³
• Volume: 3 ml; Weight: 11.1 g (0.0111 kg)
• Operating temperature range: -250 °C to 350 °C
• Electrical conductivity: none (non-conductive)

How to use

Clean both contact surfaces (CPU heat spreader and heatsink base) with isopropyl alcohol and a lint-free cloth. Apply a small, pea-sized amount of Kryonaut to the centre of the CPU die or follow the manufacturer-recommended application pattern for your cooler. Mount the heatsink and press evenly to spread the paste, then secure the cooler according to its installation instructions. Avoid applying excessive amounts; a thin, even layer provides the best thermal transfer.

Usage recommendations

Do not use Conductonaut-specific warnings for Kryonaut: Kryonaut is non-electrically conductive and suitable for use with aluminum heatsinks. Store the syringe capped and in a cool, dry place. For optimal results, reapply when replacing the cooler or if thermal performance degrades significantly.
