Thermal Grizzly debuted new high-performance thermal interfaces and exotic cooling prototypes during Computex 2026. The upcoming Duronaut Pro targets gamers and industrial systems with improved durability, while the silicon-free Hydronaut Pro focuses on liquid-cooled rigs with large heatsinks. Both pastes aim to lower temperatures further than their predecessors.

A standout prototype is the Mycro Direct-Die Diamond block, which integrates two CVD industrial-grade diamonds. These diamonds cost €500 and provide a theoretical thermal conductivity of 2200 W/m-K. While the copper-diamond hybrid outperforms standard copper plates, the extreme cost makes a retail release unlikely for most consumers.

Collaboration with Swiss firm Platit brought four new Physical Vapor Deposition coatings to the show. These PVD options improve scratch resistance, corrosion protection, and thermal efficiency. The company is currently evaluating these coatings to decide which ones will appear on future water blocks to improve long-term hardware reliability.

These prototypes demonstrate the current limits of thermal conductivity through expensive materials. Most users will likely stick to the new Pro pastes while the diamond blocks remain experimental benchmarks.
