Best selling Thermal grease

Here's a ranking of the best products in this category. To give you a quick overview, we've also added some key information about the products.

1. Thermal Grizzly Kryonaut

The Kryonaut thermal paste is ideally suited for low-temperature cooling applications such as nitrogen or compressor cooling. However, it also works excellently between a CPU and an air or water cooler. Embedded in a carrier structure are aluminum and tin oxide components that optimally compensate for unevenness on the surfaces of the heat source and the heat sink while providing outstanding thermal conductivity. Unlike many competing products, Kryonaut does not begin to dry out even at 80 °C.

2. Thermal Grizzly Kryonaut Extreme Thermal Paste

Thermal Grizzly from Hamburg is a German brand dedicated to combating high temperatures and poor heat transfer. The goal is to supply the overclocking community with high-performance thermal products, which still represent a weak point. However, the product portfolio can also be used for better and quieter cooling of gaming PCs, workstations, mini-PCs, and many other purposes. In addition to enabling higher clock rates, better thermal products allow for quieter cooling and a longer lifespan of the components being cooled.

The thermal paste named Kryonaut Extreme targets extreme overclockers with its outstanding thermal conductivity. As the name suggests, it is ideal for low-temperature cooling methods such as nitrogen or compressor cooling. Compared to Kryonaut thermal paste, the finer base particles of Kryonaut Extreme reduce the risk of cracks due to the high temperature differences in nitrogen cooling, thereby preserving thermal conductivity. Kryonaut Extreme is suitable for particularly low temperatures down to -250 degrees Celsius.

Embedded in a carrier structure are tin oxide components and particularly fine nano-alumina particles, which optimally compensate for unevenness on the surfaces of the heat source and heatsink while providing exceptional thermal conductivity. Additionally, Kryonaut Extreme is characterized by its ability to remain stable and not dry out even at high temperatures of 80 degrees Celsius, and it is not electrically conductive.

The Kryonaut Extreme thermal paste comes in a syringe with 2 g of content for approximately 6 applications—this, of course, depends on the amount used, the skill of the user, and the size of the CPU. The package also includes an applicator for precise application and distribution of the Thermal Grizzly Kryonaut Extreme.

3. Arctic Mx-4

The Arctic MX-4 is a thermal paste that offers exceptional heat transfer from components to coolers. Like its well-known predecessors in the Arctic MX series, the Arctic MX-4 is specifically designed for overclockers. The MX-4 is very easy to apply. Its new consistency makes it a breeze to apply cleanly on the chip, even with a finger. The electrically non-conductive paste is placed between the CPU/GPU and the corresponding coolers to optimize heat transfer from the chip to the cooler. Since the Arctic MX-4 is metal-free, it eliminates the risk of short circuits, thereby providing increased safety for the computer.

4. Thermal Grizzly Remove cleaning fluid

TG Remove is a specialized cleaner specifically designed for removing thermal paste. The acetone-based nano cleaner not only provides deep cleaning of surfaces but also has a degreasing effect. This allows for the safe and reliable removal of both conventional thermal pastes and liquid metal thermal pastes. Due to its degreasing properties, the TG Remove cleaner is particularly suitable for optimally preparing the surface for use with Thermal Grizzly Conductonaut.

8. Arctic Thermal compound MX-4 4 gr.with spatula

The surfaces of processor chips and cooler bases are characterized by microscopic irregularities. The Arctic MX-4 thermal paste is made from carbon microparticles that fill these gaps, resulting in extremely high thermal conductivity. This ensures that heat is dissipated quickly and efficiently from the CPU or GPU. With its outstanding performance, the MX-4 is an excellent choice for overclockers and enthusiasts, as well as for other applications where thermal transfer is required.

10. Thermal Grizzly TG-AS-3

Thermal Grizzly from Hamburg is a new German brand dedicated to the fight against high temperatures and poor heat transfer. The goal is to supply the overclocking community with high-performance thermal interface products, which have long been a weak point. However, the product portfolio can also be used for better and quieter cooling of gaming PCs, workstations, mini-PCs, and many other applications. In addition to higher clock speeds, better thermal interface products enable quieter cooling and a longer lifespan for the components being cooled.

To achieve these goals, Thermal Grizzly has closely collaborated with renowned extreme overclocker Roman "der8auer" Hartung during product development and testing, developing chemical compositions and analyzing competitors. The first product lines are now complete, meeting the highest standards of both the manufacturer and the overclocking community.

For optimal thermal conductivity of thermal pastes, proper application is just as important as a high-performance paste. In most cases, the thermal paste is delivered in small syringes, allowing only a drop of paste to be applied at a time. With the practical spatula from Thermal Grizzly, this drop can be spread particularly easily and thoroughly over the entire CPU head or other heatsinks, achieving optimal conductivity and ensuring your hardware is well-cooled.

- Color: Black
- Material: Plastic
- Quantity: 3.
