Thermal Grizzly Hydronaut

Thermal Grizzly’s Hydronaut is a high-performance thermal paste designed for users seeking efficient and stable heat dissipation—from overclockers to owners of large cooling systems. It offers an excellent performance-to-cost ratio and helps maintain low temperatures even under heavy, sustained loads.

The silicone-free formula provides a flexible, easy-to-work texture, uniform and simple application, and perfect compatibility with large coolers such as water-cooling systems (Custom Loop / AIO) and substantial air cooling.

Especially designed for wide heat-transfer interfaces

Hydronaut was engineered to deliver optimal thermal conductivity on interfaces with large contact areas—water-cooling blocks, thick radiators, and air/water systems that use high-airflow fans.

Silicone-free and with no curing time required (No Curing), the paste remains easy to work with even after opening, allows reapplication, and does not dry out quickly.

The combination of easy application, thermal stability, and high conductivity makes it an ideal choice for medium to large cooling solutions—for day-to-day quiet operation and maximum performance in overclocking.

The materials are RoHS-compliant for demanding, safe use, and suitable for most modern hardware environments.

Key advantages

• Optimized for overclocking and high-heat systems

• High thermal conductivity for temperature stability under load

• No curing time required—immediate performance after application

• Silicone-free—convenient, flexible spreading with no tendency to dry out quickly

• Electrically non-conductive—reduces the risk of shorts around sensitive components

• Broad compatibility with copper, aluminum, and nickel—for CPUs and GPUs

• Long-term stability—suitable for continuous use with minimal maintenance

Guidelines for optimal application

Clean old residues from the CPU and cooler, place a small dot in the center or apply a thin, even stripe, and tighten the cooler in a cross pattern. A small amount and a uniform layer ensure efficient thermal contact and a significant drop in temperatures.
