Top-rated products in the Thermal grease category

Here's a ranking of the top rated 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. Arctic Silver Thermopaste silver 5 (3.5g)

For better heat transfer between the processor and the fan. Should be used with all processors and fans, unless the fans are equipped with thermal pads or other materials for special heat dissipation. The paste contains silver particles that conduct heat very well. The silver particle content is approximately 99.9%. 3.5 grams is sufficient for about 20 applications. Min. 9.0 W/m°K.

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. Arctic Silver ArctiClean 30+30ml

Fighting with stubborn residues on the CPU or GPU cooler after replacing the CPU or graphics card is now a thing of the past. Often, the old thermal paste or thermal pad on the heatsink is so firmly dried that it can be incredibly frustrating. Many times, mom's nail polish remover had to come to the rescue. Stress was inevitable, and the results were not always satisfactory.

Arctic has addressed this issue and developed ArctiClean, a two-phase cleaner that easily and efficiently dissolves even the most stubborn thermal pads and thermal paste from CPUs and coolers, while the second phase prepares the surface for the application of new thermal material.

The thermal pad/paste remover ArctiClean 1 is a non-toxic, biodegradable solvent. The liquid is made from extracts of citrus fruits and soy. The scent can even be described as pleasant.

ArctiClean 2 is designed to prepare the surface cleaned with ArctiClean 1 (cooler, CPU, etc.) for new thermal paste and to remove any residues of ArctiClean 1 and/or other cleaning agents. This also helps to reduce the corrosion process of copper and aluminum.

Caution! Please read the manufacturer's warnings before use!

Contents of the package:
- 30 ml remover
- 30 ml preparation liquid.

5. Thermal Grizzly Conductonaut liquid metal

Overclockers, watch out. With the paste, the temperature of the processor can be lowered again by a few degrees without having to buy a new cooler. The application of the liquid metal is also surprisingly simple, especially as the manufacturer already includes the necessary accessories in the scope of delivery. If the use is still new at the first time, it goes at the latest from the second application quickly by the hand. Very good.

In addition, the Thermal Grizzly Conductonaut is extremely productive. The filling quantity of one gram of liquid metal is sufficient for far more than 10 applications. And if there is too much liquid metal on the processor, it can simply be sucked back into the syringe. The correct dosage is therefore very easy to handle. On average, half a grain of rice is sufficient for one processor.

Important: The Conductonaut must not be used with contact surfaces made of aluminium. Recommended materials are copper, nickel, silver and other metals. In addition, the Thermal Grizzly Conductonaut Heat Conducting Paste should be stored in its original packaging in dry rooms at room temperature.

6. 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.

7. Cooler Master Thermal Conductive Paste

Cooler Master HTK-002 thermally conductive compounds are grease-like silicone materials, heavily filled with heat conductive metal oxides. This combination promotes high thermal conductivity, low bleed, and high-temperature stability. These compounds resist changes in consistency at temperatures up to 177°C (350°F), maintaining a positive heat sink seal to improve heat transfer from the electronic device to the heat sink or chassis, thereby increasing the overall efficiency of the device.

8. 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.
