## Overview

Thermal Grizzly Duronaut is a premium 2g thermal paste engineered for exceptional heat conductivity (12.5 W/mK) and long-term stability without hardening. Its unique blend of aluminum and zinc oxide nanoparticles minimizes pump-out effects and ensures superior adhesion. Electrically non-conductive and safe for all electronics, it includes the TG Spatula Pro for precise application, making it the go-to choice for gamers, overclockers, and demanding industrial cooling setups.

## Description

Thermal Grizzly Duronaut is a high-performance thermal paste with outstanding long-term stability and excellent thermal conductivity. An ideal choice for gamers and overclock enthusiasts and serves as a top product for demanding industrial cooling systems. Product Information "Duronaut" Duronaut is a premium thermal paste that specializes in superior thermal conductivity and outstanding long-term stability. The name "Duroneau" comes from the English "durability" and emphasizes its amazing durability. This stability is achieved by combining specially designed silicone oil with aluminum particles and various shapes of zinc oxide nanoparticles. These optimized particle shape and size minimizes the "pump-out" effect, ensuring excellent adhesion to surfaces and provides extremely low heat transfer resistance. Characteristics Extreme long-term stability Superior thermal conductivity Electrically non-conductive Will not harden over time Available in 2 sizes: 2g | 6g Extremely durable and performance of PC. Optimized particle shape and size allow for an extremely thin layer of application, which increases adhesion and minimizes thermal resistance. This thin coating layer combined with the high conductivity of aluminum micro and zinc oxide nanoparticle mixture ensures efficient heat transfer between heat sources (i.e. CPU) and coolant systems. Matching accessories For optimal use, TG Spatula Pro comes with Duronaut Improved design of the spatula increases pressure during application, resulting in efficient spread and a thin thermal paste layer. Scope of Delivery 1 x Duronaut 1 x Applicator 1 x TG Spatula 1 x TG Spatula Pro

Review: Massive temp improvements - This is outstanding paste. Used on my i9-9900K overclocked at 4.8 GHz (and later my RTX 2080). Before application the CPU was failing stress tests almost instantly under 100% load. I applied a very small amount according to Igor's Lab's method, and am now able to pass stress tests with ease, and idle temps sit at ~30°C during normal use. Highly recommended.
Review: 私が今まで使ってきた安いグリスに比べ、粘り気がかなりあります。 例えるなら噛んでいるガムくらいの硬さがあります。 CPUはintel i9 14900Kを使用していますが、明らかにPCのファンの回転が減りました。 おすすめです。今後はこれをリピしようと思います。

## Questions & Answers

**Q: My thermal paste is difficult to spread or comes off the surface. What can I do?**
A: The surface should be thoroughly cleaned and be free of grease before use. The thermal paste should be at least at room temperature when applied. It is important to spread the thermal paste very slowly during application.

**Q: How long is Thermal Grizzly thermal paste usable after opening?**
A: With proper storage and packaging, the thermal paste can be used for at least 3 years without issues, and in many cases, significantly longer.

**Q: Why can't I find the thermal conductivity value on the packaging?**
A: The typically theoretical thermal conductivity values vary greatly depending on the application, as important factors such as contact pressure, temperature, or surface cannot be uniformly accounted for.

**Q: Should I store the thermal paste in its original packaging after use?**
A: Thermal Grizzly thermal paste packaging is specially coated on the inside to protect the syringe and its contents from UV radiation and other environmental influences. We recommend storing it in the original packaging.

*by 三***浪 on January 11, 2026*

オーバークロッカーが使うようなハイエンドグリスの中では比較的柔らかめで、CPUクーラーの接触面を当てて少しグリグリすれば十分延びます。具体的には定番グリスのMX-4と比較するとほんの少し硬い程度。 出たばかりのcinebench2026でマルチを265k定格360mm簡易水冷(ファンは静音性重視の弱めのもの)で10分回してみたところ、Duronautはスコア1〜2%微増・最高温度がHWMonitor読みでCPUパッケージ温度2度低下でした。爆熱の石が手元に無いので分かりませんがcore i9やryzen9に電力を盛る設定ならもっと差が付いたかも知れませんね。 あとヘラが2種類とシリンジから平たく押し出す用の先端が付属しているのは地味に便利。
