Thermal Grizzly Hydronaut Thermal Grease 3.9g

Thermal Grizzly Hydronaut – High Performance Thermal Grease 3.9 g / 1.5 mL

Built for larger-scale cooling solutions like custom water loops and high-end air coolers, Hydronaut combines a silicone-free, ultra-flexible formula with 11.8 W/mK thermal conductivity and no curing—ensuring easy application, rock-solid stability, and safe, non‑conductive performance from −200 °C to +350 °C.

Key Features

• 11.8 W/mK Thermal Conductivity: Rapidly transfers heat away from CPUs and GPUs for lower temperatures under load.
• Silicone-Free & Non-Conductive: Safe for all electronics with zero electrical conductivity.
• No Curing Required: Delivers peak performance immediately after application.
• Wide Temperature Range: Stable from −200 °C to +350 °C for both overclocking and industrial use.
• Optimal Viscosity (140–190 Pa·s): Thick enough to fill microscopic gaps yet easy to spread evenly.

Why You’ll Love It

Whether you’re building a custom loop or upgrading a high‑end air cooler, Hydronaut delivers an unbeatable balance of thermal efficiency, flexibility, and long‑term stability—making it the go‑to choice for enthusiasts and professionals alike.
