Thermal Grizzly has announced the availability of its new Duronaut Pro and Hydronaut Pro thermal pastes. The new Pro models build on their existing versions by offering improved thermal performance while keeping the key strengths that made the original products popular among PC enthusiasts and professionals.

Although the temperature gains may appear small in laboratory testing, Thermal Grizzly says these improvements are important because modern thermal paste technology already operates close to its performance limits. Even minor reductions in temperature can help improve cooling efficiency in demanding systems.

The company measures thermal performance using temperature difference between a heat source and a cooler under controlled conditions. According to Thermal Grizzly, this method provides a more realistic comparison than simply listing thermal conductivity values in W/(m × K).

Duronaut Pro Focuses on Long-Term Reliability

Duronaut Pro is designed for users who want strong cooling performance and long-term stability. The thermal paste uses a specially developed silicone oil combined with aluminum micropowder and zinc oxide nanopowder to improve heat transfer.

Thermal Grizzly says the optimized particle size and shape help reduce the pump-out effect, where thermal paste gradually moves away from the contact area over time. This allows the paste to maintain better contact between a processor and its cooler.

The paste can also be applied in a very thin layer, helping reduce thermal resistance and improve heat transfer efficiency.

Key features of Duronaut Pro include:

• Excellent thermal conductivity
• Extreme long-term stability
• Electrically non-conductive
• No curing required

Hydronaut Pro Targets Industrial Applications

Hydronaut Pro is designed for both enthusiast PCs and industrial systems. Unlike many traditional thermal pastes, it uses a silicone-free carrier structure.

In some industrial environments, silicone-based oils can affect nearby materials and seals. Hydronaut Pro avoids this issue while still providing strong thermal performance. The company says the paste is resistant to problems caused by temperature changes and is suitable for systems where silicone-based materials are not preferred.

The product is also RoHS compliant and designed for easy application.

Key features of Hydronaut Pro include:

• Suitable for industrial applications
• Outstanding thermal conductivity
• Silicone-free design
• Electrically non-conductive
• No curing required

With the launch of Duronaut Pro and Hydronaut Pro, Thermal Grizzly continues to expand its lineup of premium thermal interface materials for gamers, PC builders, overclockers, and industrial users looking for reliable cooling performance.

Thermal Grizzly has announced two new high-performance thermal interfaces, the Duronaut Pro and Hydronaut Pro, offering enhanced thermal conductivity over their standard predecessors.

The manufacturer developed Duronaut Pro with a focus on long-term stability and reduced pump-out effects. This compound combines a specialised silicone oil with aluminium micropowder and zinc oxide nanopowder to minimise contact resistance, allowing users to apply it in a very thin layer. According to the product documentation, this specific mixture remains electrically non-conductive and won't cure over time.

Hydronaut Pro targets industrial systems by utilising a completely silicone-free carrier structure. Standard silicone-based pastes can suffer from oil bleeding or mechanical displacement during repeated temperature fluctuations, which can degrade performance or damage adjacent sealing materials such as EPDM or NBR. Thermal Grizzly states that this RoHS-compliant formulation avoids these structural risks while maintaining high conductivity without curing.

Laboratory testing conducted by the company measures performance using a 30x30mm contact surface under a 240W heat flow with 300N of force. Based on the test results, you can expect around a 4% improvement moving from Duronaut/Hydronaut to Duronaut/Hydronaut Pro. Both thermal paste solutions are now available, with the Duronaut Pro starting at €17.90 (2g) and the Hydronaut Pro starting at €14.90 (2g).

KitGuru says: Thermal Grizzly just expanded its lineup, offering even more options for those looking for something more than what comes included with their coolers.
