EK Water Blocks, Slovenia-based premium liquid cooling gear manufacturer, is now offering Thermal Grizzly Hydronaut thermal grease in its liquid cooling TIM portfolio.


Thermal Grizzly Hydronaut

Thermal Grizzly Hydronaut is a very high-performance thermal grease, which shows its true capabilities in cryogenic environments. Hydronaut thermal grease sports high long time stability, all without curing. Hydronaut thermal grease is silicone-free.



Hydronaut can be used for overclocking due to its excellent thermal conductivity, but it was created specifically for users with large-scale cooling solutions, who are looking for a quality product with an excellent price-performance ratio.

Thermal Grizzly Hydronaut is best applied with the enclosed Thermal Grizzly applicator, but it can also be applied by way of brush, spatula, silkscreen or pad printing.



Two Thermal Grizzly applicators are enclosed.

Thermal Grizzly Hydronaut thermal grease is available for purchase as the special syringe in the 3.9g package. 1g package is now also enclosed with every EK-Supremacy EVO water block (on the image below).
