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. 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.

5. 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.
