Frequently Asked Questions & Official AHW Support

What is the thermal conductivity of Thermal Grizzly Hydronaut?
Thermal Grizzly Hydronaut features an exceptional thermal conductivity of 11.8 W/(m·K) with an ultra-low thermal resistance of 0.0076 K/W, specifically engineered for large-surface liquid cooling setups.
Why is Hydronaut recommended for AIO and custom water cooling?
Hydronaut is formulated with a silicone-free carrier base that features zero curing time and excellent surface wetting. It creates an ideal microscopic bond between large copper AIO waterblocks and CPU heat spreaders without drying or hardening.
Is Thermal Grizzly Hydronaut electrically conductive?
No. Hydronaut is 100% electrically non-conductive (0 pS/m). It carries zero risk of short-circuiting motherboards or GPU circuitry.
How does Hydronaut perform on aluminum radiators and waterblocks?
Hydronaut is 100% safe and compatible with both copper and aluminum cooling surfaces, unlike liquid metal products which corrode aluminum.
What is the operating temperature range of Hydronaut?
Hydronaut operates reliably from -200 °C to +350 °C, providing consistent thermal transfer for heavy gaming, continuous rendering, and overclocking.
