Thermal Grizzly
Thermal Grizzly Conductonaut Extreme - 1 g
Best liquid metal for expert PC builders seeking maximum thermal performance.
The Thermal Grizzly Conductonaut Extreme is an advanced liquid metal thermal compound engineered for applications demanding the highest power density. This gallium-based alloy remains liquid at room temperature, ensuring an extremely thin application layer for superior thermal transfer, unlike traditional pastes. It excels in high-energy scenarios by eliminating the gaps caused by solid particles. Manufactured in Germany under strict quality control, it is recommended for experienced users seeking best-in-class heat dissipation above 8°C. For optimal long-term stability, apply this electrically conductive material only on nickel-plated copper surfaces, as it must not contact aluminum.

What customers say
Users regard Conductonaut Extreme as the top thermal material, consistently noting significant temperature drops compared to standard pastes. This exceptional performance appeals strongly to overclockers seeking maximum headroom. However, this high reward comes with serious usability caveats. Reviewers emphasize the critical need for careful application due to the liquid metal's electrical conductivity, warning that errors risk short circuits. Furthermore, incompatibility with aluminum heatsinks is a major concern, requiring specific copper cooling solutions. While performance justifies the premium cost for experts, the steep learning curve and potential for hardware damage mean this product is strictly for experienced builders who understand the necessary safety precautions.
Know before you buy
No. Because this is a gallium-based liquid metal, it must never be used with aluminum heatsinks, as it will cause rapid corrosion. It is only safe to use on nickel-plated copper surfaces.
Yes, it is electrically conductive. You must be extremely careful during application to ensure no liquid metal spills onto your motherboard components or pins, as this could cause a short circuit.
Unlike traditional pastes, this is a liquid metal alloy that creates a much thinner bond line between the heat source and the cooler. This allows for significantly better thermal transfer, making it ideal for high-performance systems.
This product is intended for experienced PC builders. The application process requires precision and a clear understanding of how to handle conductive materials to avoid damaging your hardware.
The product includes a specialized metal needle designed for precise application. Use it to apply a very small amount to the center of the heat spreader and spread it thinly and evenly across the surface.
The material is liquid at room temperature, but it performs best in environments above 8°C. Ensure your workspace is at a comfortable room temperature during application to maintain the ideal viscosity.
