⚡ Engineering Highlights at a Glance:

• Extreme Long-Term Stability: The name Duronaut comes from “durability.” The paste resists degradation and maintains performance over many thermal cycles, which matters most on GPUs where pump-out is common.
• Excellent Thermal Conductivity: The combination of aluminum micropowder and zinc oxide nanopowder of various shapes provides efficient heat transfer between the CPU or GPU and the cooler.
• Minimized Pump-Out Effect: Optimized particle shapes and sizes reduce the paste’s tendency to be squeezed out from between the die and cooler as temperatures rise and fall.
• Electrically Non-Conductive: Because the paste does not conduct electricity, it is safe to use near exposed contacts and SMD components without risk of short circuits.
• Does Not Harden Over Time: Unlike some pastes that dry out and become brittle, Duronaut Pro remains pliable, which preserves contact pressure and thermal transfer.
• 2g Precision Size: Ideal for a single CPU or GPU installation, with minimal waste for occasional builders.
• Includes TG Spatula Pro: The revised spatula design allows more pressure during spreading, which helps achieve a thinner, more even layer.

Handling and Storage

Store the syringe at room temperature and keep the cap on when not in use. Because Duronaut Pro has a thicker consistency, you may find it easier to work with if you let the syringe sit in a warm room for a few minutes before application. Do not heat the syringe directly or expose it to open flame. Keep the paste away from children and pets, and avoid contact with eyes or skin. If you get paste on your skin, wash with soap and water.

Do Not Apply Too Much

Using too much paste can be counterproductive. A thick layer acts as an insulator instead of a conductor, and excess paste can spill onto the motherboard. A pea-sized dot is sufficient for standard desktop CPUs. Because the mounting pressure spreads the paste, you do not need to cover the entire heat spreader manually.

⚠️ Disclaimer

Thermal paste application involves handling delicate electronic components. If you are not comfortable disassembling your PC or GPU, have a qualified technician perform the service. Alfrensia is not responsible for damage caused by improper installation or handling. Always follow the instructions provided by your cooler or GPU manufacturer, as some manufacturers void warranties if the cooler is removed.

Duronaut Pro is a strong choice when long-term stability matters most. If you are building a system once and want it to maintain consistent temperatures for years without repasting, Duronaut Pro is a good fit. It is especially well suited for graphics cards, where pump-out degrades lesser pastes more quickly. For CPU-only builds with standard cooling, Duronaut Pro also performs well, but its main advantage is durability rather than an initial temperature drop that is noticeably different from other high-end pastes. Because the 2g syringe contains enough paste for one CPU or GPU installation, it is a practical size for users who service only their own systems. If you are applying paste for the first time, take your time with the spreader and use a pea-sized amount; the included TG Spatula Pro makes it easier to achieve a thin, even layer. For best results, clean both surfaces thoroughly with isopropyl alcohol and tighten the cooler in a diagonal pattern.
