Who it is for
The paste was developed for enthusiasts, overclockers and professionals seeking the highest levels of cooling performance and long-term reliability. Thermal Grizzly calls it an ideal high-end paste for gamers and overclockers, and recommends it as a top-tier product for demanding industrial cooling systems. That covers high-performance CPUs and GPUs and other demanding cooling applications, with dependable operation in gaming PCs, workstations, servers and overclocked systems. The 30g version is ideal for frequent system builders, professional technicians and enthusiasts who regularly service multiple systems. Whether you're assembling flagship gaming PCs, optimizing professional workstations or maintaining multiple systems, the aim is the same: outstanding thermal efficiency and long-lasting reliability you can count on.
Features
- Extreme long-term stability with minimal pump-out
- Enhanced thermal conductivity for superior cooling performance
- An electrically non-conductive formula, which provides additional installation safety
- Will not dry out or harden over time, and the paste needs no curing
Long-term stability and the pump-out effect
The name "Duronaut" is derived from the English term "durability." Building on the proven Duronaut formula, this premium version delivers enhanced thermal conductivity while maintaining exceptional durability. Thermal Grizzly gets that stability from a specially engineered silicone oil and an advanced formulation that combines aluminum microparticles (micropowder) with zinc oxide nanoparticles (nanopowder) in optimized shapes and sizes. The carefully balanced particle structure minimizes the pump-out effect, the expulsion of paste caused by repeated thermal cycling between a heatspreader and a cooler, while providing excellent adhesion to the surface. The data sheet adds that pump-out increases significantly at high temperatures. It is particularly critical between materials with differing coefficients of thermal expansion, for example a silicon GPU chip and a copper heatsink. Designed for years of consistent performance, the paste remains stable over extended use without drying out or hardening.
Ultra-thin layers
The formula is optimized for ultra-thin application layers. A silicone matrix serves as the carrier material and is filled with a high proportion of thermally conductive fillers, the aluminum microparticle and zinc oxide nanoparticle mix. Thanks to its small particle size the paste goes on as an ultra-thin application layer, which the data sheet calls an extremely thin bond line. The result is extremely low thermal contact resistance, ensuring highly efficient heat transfer between the heat source (e.g., a CPU) and the cooler.
Applying it
Every package includes the redesigned TG Spatula Pro for the best possible application, and the 30g version also includes the standard TG Spatula. The Pro has an improved design, allowing greater pressure on the surface during application and making it easier to spread the compound efficiently into an exceptionally thin and even layer.
