Thermal Grizzly Releases Duronaut High-Performance Thermal Paste with Exceptional Long-Term Stability

Thermal Grizzly's Duronaut thermal paste stands out due to its combination of exceptional long-term stability and excellent thermal conductivity. Its outstanding performance in heat transfer is further enhanced by the ability to apply Duronaut in an extremely thin layer. This is made possible by its unique composition of aluminium microparticles and zinc oxide nanoparticles, optimized for particle shapes and sizes. These features ensure excellent adhesion of the paste to the surface. The powders are mixed into a specially developed silicone oil, resulting in extraordinary long-term stability.

For optimal application, the high-end thermal paste comes with the new TG Spatula Pro. The redesigned spatula allows for more pressure to be applied to the surface during application, enabling the paste to be spread more efficiently in a thinner layer. Duronaut is available in 2-gram and 6-gram packaging options.
Duronaut is a high-end thermal paste designed with a focus on outstanding thermal conductivity and exceptional long-term stability. The name "Duronaut" derives from the English word "durability," emphasizing its extraordinary longevity. This stability is achieved through a specially engineered silicone oil combined with aluminium microparticles and zinc oxide nanoparticles of various shapes. These optimized particle shapes and sizes minimize the "pump-out effect," ensuring excellent adhesion to surfaces and resulting in extremely low thermal transfer resistance.
  • Extreme long-term stability
  • Outstanding thermal conductivity
  • Electrically non-conductive
  • No hardening over time
The optimized particle shapes and sizes enable Duronaut to be applied in very thin layers, enhancing adhesion and minimizing thermal resistance. This thin application layer, coupled with the high conductivity of the aluminium micro and zinc oxide nanoparticle mix, ensures efficient heat transfer between the heat source (e.g., a CPU) and the cooler.

For optimal application, the TG Spatula Pro is included with Duronaut. The spatula's revised design allows for increased pressure during application, ensuring efficient spreading and a thinner layer of thermal paste.

Scope of Delivery
1x Duronaut
1x Applicator
1x TG Spatula
1x TG Spatula Pro

Thermal Grizzly Duronaut is available directly from Thermal Grizzly website in 2 g and 6 g versions, priced at $10.79 and $19.51, respectively.

The only reason why I never bought from him is because his other TIMs do not stand the test of time, or heat.. by his own admission.

This stuff should be interesting.

I can confirm that. Kryonaut Extreme that i have dries out in roughly a year but starts losing performance before that.

Yes I at least appreciate that he doesnt really try to obfuscate that quality though. It seems like other content creators fail to disclose these kinds of things more than Roman.

At roughly 80-85c is where it will start to fall apart from what I have read.. I think the big man might have even said that too

I'm sorry for an excessive scepsis. I haven't try any Thermal Grizzly yet myself. But it's funny, how every single their product is advertised by "techtubers" as a superior thermal solution, with long dry-up period. While the tests and forums/reddit is full of posts and info, that refutes these claims, by how quick their pastes dry up. It can be as short as two weeks of contemporary use. How much this product will differ from their previous claims is yet to be proven by real tests.

I'm interested. This stuff would work great on a device I would never want to open again... like my vintage PlayStations.

I tried it... it had completely dried in about a year. There was only some weird oil on top of my 13900KS when I retrieved it from my old motherboard. I had decided to do something because I noticed my temperatures were really bad by the time I bothered to look. Pink dust almost everywhere else... I liked Kryo Extreme, but it truly is only good for a month tops at high TDP applications

I use Thermal Grizzly because it is the best in temps. Though I don't leave it on for more than a few years so I cannot comment when it starts to show signs of thermal wear.

All these people complaining about paste dry out... You lack any kind of test methodology or credibility. Pure hyperbole. You have zero valid comparisons unless you performed tests with the same exact chipset drivers, BIOS, Windows versions, Windows updates, background tasks, system cleanliness, room temperature and humidity. Comparing with any of those variables unchecked with any amount of time in between results in completely invalid conclusions.

I build workstations and maintain them for a living. I use Aeronaut, Hydronaut, Kryonaut, Noctua NT-H1/2, and I've only ever seen dry out picture after 2+ years; it was Kryonaut and wasn't even that dry. I've had Kryonaut Extreme on my personal system for over a year and it's been phenomenal. I recently upgraded that CPU and the paste was still spreadable and moist.

Everyone else must be wrong. Only you are right. /s

Have you considered that maybe people who experience dryout run at higher temperatures or more heat cycles in another climate?
Then you say all results are invalid unless performed in the same day with like for like conditions.
Tell me how exactly is one supposed to test paste aging in a single day?
