The choice for overclockers

„Kryo" - the greek word for "cold" - also found in the german word for "cryoengineering", suggests that this thermal paste was created especially for cryogenic applications. For the true "Kryonauts" amongst the "extreme overclockers".

Kryonaut uses a special structure, which halts the drying out process at temperatures of up to 80° Celsius. This carrier structure ensures that the nano-aluminum and zinc oxide components of the paste bond optimally, to compensate for unevenness of the component (i.e. the CPU) or the heat sink, thus achieving remarkable heat transfer.

How can I check whether my Kryonaut is genuine, and what should I do if the verification code is invalid?

If your Kryonaut package includes an authentication card, check the code on the official website printed on it. A missing code or different packaging alone does not prove that a product is counterfeit, as package contents and packaging can vary by product and batch. If the code is invalid, send us photos of the product, packaging, code and proof of purchase so we can check them. Whenever possible, buy from a retailer on our reseller list.

Which version of Kryonaut suits my application, and what thermal conductivity and cooling performance does it offer?

Kryonaut is designed for high cooling performance and demanding applications, including overclocking. The temperature you can achieve depends on power consumption, the cooler, the contact surfaces and installation. In terms of cooling performance, Kryonaut ranks just behind Duronaut and Duronaut Pro. Ideally, use independent tests for comparison. Thermal Grizzly has not published general W/(m·K) ratings since the end of 2020. A single thermal conductivity value does not allow a reliable comparison of cooling performance, as the test method, temperature, mounting pressure and contact surfaces all affect the result.

Where can I find instructions, datasheets and safety or compliance documentation for Kryonaut?

Available instructions, technical data sheets, safety data sheets and conformity documents for Kryonaut can be found in the downloads section of the product page. Check the exact product name and item number. A technical data sheet does not replace a safety data sheet. If a document or language version is missing, tell us the item number and which document you need.

How long does Kryonaut last in use, what is pump-out, and when should I replace it?

There is no universal replacement interval for Kryonaut once installed in a system. Check temperatures under comparable loads and at comparable ambient temperatures. Replace the paste if temperatures show a confirmed deterioration or if you have removed the cooler. A universal service life cannot be specified. Temperature changes can gradually displace thermal paste from the contact area, a process known as pump-out. A thin, even layer of Kryonaut and correct cooler installation reduce this risk, but cannot eliminate it in every configuration. Duronaut and Duronaut Pro are designed for particularly high long-term stability. If temperatures rise again, also check the contact pattern. Kryonaut works best between two copper or nickel-plated surfaces.

How do I apply the correct amount of Kryonaut in a thin, even layer?

Clean and degrease the CPU or GPU and the cooler's contact surface, then let them dry. Apply Kryonaut at room temperature to clean, dry contact surfaces. Use the spatula to spread the paste slowly into a thin layer, applying even pressure. Avoid fast wiping movements, as they can lift the paste off the surface again. A thick consistency is not a defect in itself. It is intentional, as it improves long-term stability. Do not use solvents or oils to thin the paste, and do not press on the edges of exposed dies. Warming the product with a hair dryer can make it easier to apply. The amount needed depends on the contact area. Cover it completely with a thin layer, especially on exposed dies. A thick layer or a large amount extending beyond the contact area is not necessary. However, applying too much does not result in worse temperatures. Excess paste is squeezed out of the gap.

Why are temperatures with Kryonaut too high or higher than expected?

First check that the cooler is seated correctly, the mounting pressure is even, the fans or pump are working correctly (for liquid cooling), and the contact surface is fully covered. When reinstalling the cooler, remove old residue and apply a fresh, thin layer of Kryonaut. Compare temperatures at the same room temperature and power consumption. CPU boost can turn improved heat transfer into higher performance rather than lower temperatures. Therefore, always check whether the CPU or GPU clock speed has changed as well.

Is Kryonaut suitable for laptop CPUs and GPUs?

Kryonaut can be used on CPU and GPU dies in laptops if the cooling system is designed for thermal paste and makes reliable contact. Cover the entire die with a thin layer. Larger gaps around memory and voltage regulators require suitable pads or putty. If pump-out keeps occurring, long-term stability and the specific cooler geometry matter more than a general comparison value. Duronaut or Duronaut Pro are generally better suited to laptops.

How should I store Kryonaut, and how long can an opened or unopened pack be stored?

After use, seal the Kryonaut syringe tightly and store it in its original packaging in a dry place, protected from light and major temperature fluctuations. Shelf life is different from service life once installed in a system. Before using older paste, check it for contamination and unusual consistency. If you are unsure, we can check the batch using photos and purchase details. An unopened tube of Kryonaut can be used for up to 10 years, and an opened tube for up to 5 years without any problems.

What temperature range and extreme conditions is Kryonaut suitable for?

Kryonaut was developed for a temperature range of −250 to +350 °C. This material specification is not a blanket approval for every continuous high-temperature process. For special applications, exposure duration, contact materials, layer thickness and mechanical loads must be assessed separately.

How do I remove Kryonaut or clean the contact surfaces?

First remove Kryonaut from the surface using a dry, lint-free cloth. Then clean the surface with isopropyl alcohol or a material-compatible TIM cleaner such as TG Remove. TG Cleaning Wipes include both dry wipes and wet wipes soaked in cleaning agents. Keep cleaning agents out of sockets and connectors, and allow all surfaces to dry completely. Use fresh paste when reinstalling the cooler.

Is Kryonaut compatible with my CPU, GPU or cooler combination?

Kryonaut is intended for direct contact between the CPU or GPU and a correctly installed cooler. Conventional thermal pastes can be used on common copper, nickel or aluminum contact surfaces. Follow the cooler manufacturer's instructions. Larger gaps around VRAM or VRMs require suitable pads or putty. The paste is not suitable for bridging gaps larger than 0.2 mm.

Is Kryonaut electrically conductive, and how do I prevent short circuits?

Kryonaut is not electrically conductive. Nevertheless, only apply the paste to the intended contact surface. Residue in the socket or on connector contacts can interfere with mechanical and electrical contact. The paste is not a certified electrical insulator for high-voltage applications.

Is Kryonaut suitable for direct-die cooling or a delidded CPU?

In principle, Kryonaut can be used directly on a silicon die if the cooler and its mounting system are designed for this purpose. For Thermal Grizzly direct-die coolers and the underside of our High Performance Heatspreaders, we recommend using liquid metal such as Conductonaut or Conductonaut Extreme. General suitability for thermal paste does not override this product-specific requirement. Kryonaut can be particularly susceptible to pump-out in direct-die CPU applications.
