Thermal Grizzly has introduced two new thermal interface materials, Duronaut Pro and Hydronaut Pro. The manufacturer claims the new products offer superior thermal conductivity compared to existing products without the Pro name.

In addition to improving thermal conductivity, special attention was paid to maintaining its stability over long periods of use and reducing the effect of thermal interface material extrusion from the base of the cooling system element that contacts the processor. In the case of Duronaut Pro, the thermal paste is formulated with a special silicone oil, aluminum micropowder, and zinc oxide nanopowder. This composition, among other things, reduces contact resistance and allows for the thermal paste to be applied in a very thin layer. According to the manufacturer, this composition allows the thermal paste to remain dielectric and not harden over time.

Hydronaut Pro is aimed at industrial users and is silicone-free. As Thermal Grizzly explains, conventional thermal pastes based on silicone oil can displace the oil over time or be squeezed out from under the radiator or water block base, especially under conditions of constant temperature fluctuations. In addition to damaging the thermal paste itself, this can damage adjacent sealing materials. According to Thermal Grizzly, Hydronaut Pro thermal paste is immune to these issues and provides high thermal conductivity over long periods without curing.

Both thermal pastes are now available in Europe. Duronaut Pro prices start at €17.90 for a 2g tube and go up to €79.90 for a 30g tube. Hydronaut Pro costs €14.90–€49.90 depending on the tube size.
