Excellent Thermal Conductivity

The surfaces of processor chips and cooler floors are covered with microscopic dents; ARCTIC‘s MX-2 thermal paste is composed of carbon microparticles which fill these cavities. This creates a surface conducive to extremely high thermal conductivity, guaranteeing fast and efficient heat transfer from the CPU or GPU to the cooler. With its outstanding performance, MX-2 is one of the top thermal pastes on the market.

Easy Application

The consistency of the MX-2 allows even beginners to apply it easily. The video below demonstrates the application technique to avoid air pockets between processors and coolers.


Secure Usage

Unlike with liquid metal or pastes containing metal oxide, you don't have to worry about short circuits when using our pastes. The MX-2 itself is not conductive, and using it will not cause corrosion damage.

Long-lasting Durability

When it comes to durability, MX-2 is uncompromising - unlike metal or silicone paste. When applied properly, it has a shelf life of up to eight years.

Incredible Value, Unbeatable Price

Thanks to its excellent price / performance ratio, the MX-2 knows how to convince many gamers and system integrators.

Available in Various Sizes

ARCTIC MX-2 comes in tubes ranging from 2 to 65 g. Resealable packaging prevents the paste from drying out.

Proven quality

While the packaging of our thermal paste has changed several times over the years, the composition of the formula has remained the same. Our MX pastes have long stood for high performance and quality, and with our new, recyclable packaging, we aim to reduce CO2 emissions and thus make a contribution to the environment.

Since the mere thermal conductivity value cannot provide any information about the actual performance, we put our thermal grease up against a broad field of competitors under laboratory conditions. The temperature difference between CPU and cooler base was measured.

How is it tested?

The temperature difference between the CPU IHS and the cooler base is determined with a laboratory device. This allows precise adjustment of the power and contact pressure to be transmitted and highly accurate temperature measurement. The contact surfaces are milled flat with very fine grooves, which corresponds to high-quality CPU coolers.

transmitted power: 150 Watt( ≈ AMD Ryzen 7 3700X All-Core-Boost) 

Contact area: 16,0625 cm2 [according to an AM4 CPU]

Contact force: 562.5 N (≙57.359 kgf or lb)

Why are CPUs only conditionally suitable for measuring the performance of thermal paste?
The thermal resistance between the CPU DIE and the IHS can change considerably over time. The measuring sensors in the DIE are not very accurate, so we use a laboratory device here.
Why are the stated thermal conductivity values of a paste not meaningful?
Often the values are stated many times too high and have nothing to do with reality. Typical values of a high-performance paste are between 1 and 5 W/mK. Just as important as the thermal conductivity value is the minimum layer thickness of a paste (at a given contact pressure) in order to minimise the temperature difference between CPU and cooler.
