Thermal Grizzly Duronaut Pro Review
Thermal Grizzly Duronaut Pro is a non-conductive, non-curing aluminum and zinc oxide thermal paste for high-end CPUs and GPUs, sold in 2g, 6g and 30g tubes with the TG Spatula Pro.
Thermal Grizzly Duronaut Pro is a newer, improved revision of the brand's long-term stability flagship, shown at Computex 2026 and released in June 2026. It blends aluminum micropowder and zinc oxide nanopowder with a specially developed silicone oil, stays fully non-conductive (0 pS/m), does not harden over time, and is built to minimize pump-out. It is sold alongside the original Duronaut as a separate SKU, not as a replacement.
Thermal Performance and Conductivity
Thermal Grizzly does not publish a W/mK conductivity figure for Duronaut Pro, so it cannot be compared on that number alone. It sits in the same long-term stability flagship tier as the original Duronaut, with a revised formula aimed at even better durability.
Composition and Formula
Aluminum micropowder and zinc oxide nanopowder are blended with a specially developed silicone oil. The mix is designed to spread into very thin layers and stay in place across years of heat cycles.
Electrical Safety
Electrical conductivity is rated at 0 pS/m, so the paste is non-conductive and safe around exposed SMD components near the die.
Longevity and Pump-Out
The paste does not harden or cure over time and is formulated to minimize pump-out, the main reason conventional pastes lose performance on large, hot dies.
Package and Applicator
Available in 2g, 6g and 30g tubes. The 2g tube lists at $20.94 (about $10.47 per gram). Every tube includes the TG Spatula Pro, designed for very thin, even layers.
Duronaut Pro vs Duronaut
Duronaut Pro is a separate, newer SKU rather than a replacement. Buyers already happy with Duronaut can stay on it; Duronaut Pro is for those who want the newest formula revision.
Our verdict

Expert rating9.1 / 10
The newest revision of Thermal Grizzly's stability-focused flagship, built for the most demanding overclocked and industrial systems.
Best for
- Users who already like Duronaut and want the newest formula revision from Computex 2026.
- Extreme durability and anti-pump-out use cases, such as large, hot CPU and GPU dies that are rarely repasted.
- Industrial and other demanding cooling systems that Thermal Grizzly explicitly targets with this paste.
Not for
- Budget builds where the original, cheaper Duronaut or Arctic MX-6 already does the job.
