Thermal paste Thermal Grizzly Hydronaut

Thermal Grizzly Hydronaut is a high-performance thermal paste designed for medium- to large-scale cooling solutions such as water cooling loops. With a thermal conductivity of 11.8 W/m·K and a density of 2.6 g/cm³, the 1.5 ml syringe provides reliable heat transfer for CPUs and GPUs while remaining silicone-free and electrically non-conductive.

Advantages

Hydronaut offers excellent thermal conductivity and is suitable for overclocking applications while being silicone-free and not electrically conductive. The compound does not cure, remains flexible after application, and is formulated to be compatible with common cooling materials (note: warnings regarding aluminum apply only to Conductonaut). It is ROHS-compliant and optimized for larger cooling setups like custom water cooling systems.

Suitable for

• Custom water cooling loops for CPUs and GPUs
• High-performance air cooling on medium- to large-sized heatsinks
• Overclocked systems requiring improved heat transfer

Key specifications

• Thermal conductivity: 11.8 W/m·K
• Density: 2.6 g/cm³
• Volume: 1.5 ml (syringe)
• Weight: 3.9 g
• Operating temperature range: -200 to 350 °C
• Silicone-free, non-curing, electrically non-conductive
• ROHS-compliant

How to use

Clean the contact surfaces (CPU/GPU heat spreader and cooler base) thoroughly with isopropyl alcohol and a lint-free cloth. Apply a small, pea-sized or line-shaped amount of Hydronaut to the center of the processor heat spreader. Mount the cooler and fasten according to the manufacturer's instructions to spread the paste evenly. For water cooling blocks or large heat spreaders, ensure even pressure and correct alignment to achieve optimal coverage.

Recommendations

Use Hydronaut primarily on medium- to large-scale cooling solutions such as water cooling systems or large heatsinks. Avoid relying on this product where electrical conductivity is a concern (it is non-conductive) and note that specific aluminum-compatibility warnings apply only to different Thermal Grizzly products (Conductonaut).
