Thermal Grizzly has added two high‑end thermal pastes to its lineup: the Duronaut Pro and Hydronaut Pro. Both replace their standard siblings with modestly lower temperature deltas under a 30 × 30 mm, 240 W test bench, but the gains matter because the paste market leaves little headroom for improvement. Manufacturers and enthusiasts alike will notice the edge.

Duronaut Pro focuses on long‑term stability. A silicone‑oil carrier combined with aluminium micropowder and zinc‑oxide nanopowder yields a thin, electrically non‑conductive layer that resists pump‑out and maintains low contact resistance over years of operation. Test data show a reduced delta Kelvin compared to the original Duronaut, indicating tighter heat transfer between CPUs and coolers. This stability translates to fewer maintenance cycles.

Hydronaut Pro drops silicone altogether, using a silicone‑free carrier that avoids oil bleeding and material incompatibility in industrial environments. The paste meets RoHS standards and delivers thermal performance on par with the best consumer offerings, making it suitable for demanding servers or equipment that contacts EPDM or NBR seals. Early adopters report lower idle temperatures. Both products arrive now, expanding Thermal Grizzly’s premium portfolio.
