High-performance thermal compound

Thermal Grizzly Kryonaut is a premium thermal paste formulated for extreme overclocking and critical industrial cooling systems. It delivers 12.5 W/m·K thermal conductivity to transfer heat efficiently between a CPU or GPU die and the cooler cold plate. The 11.1 g syringe provides enough compound for multiple applications. It contains no electrically conductive materials.

Verify cooler mounting and surface condition

Ensure the cooler mounting mechanism can apply even pressure across the integrated heat spreader without excessive force that could pump out the paste. Confirm both the die and cold plate are free of old compound residue, oils, or oxidation before application. The paste operates reliably from -250 °C to +350 °C, so confirm your cooling solution stays within this envelope. No curing time is required after installation.

Fills microscopic gaps for stable long-term contact

The nano-aluminum and zinc oxide particle structure resists drying out at temperatures up to 80 °C, maintaining consistent thermal performance over extended periods. Its viscosity range of 130 to 170 Pas allows easy spreading while preventing migration under thermal cycling. The non-conductive formula eliminates the risk of short circuits if paste contacts surrounding components. A 3 ml volume covers several standard desktop processor installations.

Questions about this item

What is included with the 11.1 g syringe and does it come with any application tools?

The package contains the 11.1 g syringe of Kryonaut paste with a volume of 3 ml. No spreader, spatula or cleaning wipes are included.

The product lists viscosities of 130–170 Pa·s and 120–170 Pa·s; which figure should I expect?

The manufacturer highlights quote 120–170 Pa·s while the detailed specs list 130–170 Pa·s; both ranges overlap, so the paste will fall within 130–170 Pa·s in practice.

What does the 12.5 W/m·K conductivity mean for my CPU temperatures once the paste is applied?

The 12.5 W/m·K rating indicates very high heat transfer between the CPU and cooler, helping lower core temperatures under heavy loads and supporting stable overclocks up to 80 °C without the paste drying out.
