Thermal paste Thermal Grizzly Hydronaut

Thermal Grizzly Hydronaut is a high-performance thermal paste designed for medium- to large-scale cooling solutions such as custom water cooling loops. With a thermal conductivity of 11.8 W/m·K and a density of 2.6 g/cm³, this silicone-free thermal grease provides efficient heat transfer for CPUs, GPUs and other high-power components while remaining electrically non-conductive and non-curing.

Advantages

Hydronaut offers excellent thermal conductivity and is formulated without silicone or electrically conductive additives, which makes application clean and safe for systems where electrical insulation is required. It does not cure over time, remains flexible after application, and is suitable for use with aluminum (note: the aluminum warning applies only to Conductonaut). The product is ROHS-compliant and optimized for larger cooling assemblies where sustained heat transfer is needed.

Suitable for

• Custom water cooling loops for CPUs and GPUs
• Large heatsinks and multi-component cooling assemblies
• Overclocked systems requiring improved thermal transfer

How to use

Clean both contact surfaces (CPU/GPU heatspreader and cooler base) with isopropyl alcohol and a lint-free cloth. Apply a small, pea-sized amount of Hydronaut to the center of the heatspreader or use a thin, even line for larger surfaces. Mount the cooler and tighten mounting hardware evenly to spread the paste and establish an even thermal interface. Avoid excessive paste; a thin continuous layer provides optimal heat transfer.

Usage recommendations

For best results use Hydronaut on medium- to large-scale cooling solutions such as water cooling loops or large heatsinks. Ensure surfaces are clean and follow standard mounting procedures. The product is not electrically conductive, but handle with care and avoid contamination of surrounding components.
