ARCTIC MX-4 thermal paste

Make the best of your high-end processor and CPU cooler. This high-performance thermal grease fill the micro gap between the CPU surface and heatsink floor of the cooler to efficiently transfer heat from the CPU. Easy to apply, the MX-4 comes in a syringe packaging, and has a resealable cap for future use with your desktop, as well as laptop, game console, and more.

Highest Thermal Conductivity

The surfaces of processor chips and cooler floors are covered with microscopic dents; ARCTIC‘s MX-4 thermal paste is composed of carbon microparticles which fill these cavities. This leads to extremely high thermal conductivity, guaranteeing that heat is dissipated quickly and efficiently from the CPU or GPU. With its outstanding performance, the MX-4 is not only an excellent choice for overclockers and enthusiasts, but also for other applications that require thermal transmission. MX-4 proves without a doubt that great performance does not necessarily require a high price.

Easy Application

Thanks to its consistency, MX-4 is easy to apply, even for beginners. The video at the bottom demonstrates the application technique to avoid air pockets between processors and coolers.

Secure Usage

In contrast to pastes based on metal oxides or liquid metal, ARCTIC’s MX-4 is metal-free and not electrically conductive. This eliminates the risk of short circuiting, and eliminates the need to worry about corrosion damage to the radiator floor caused by liquid metal.

Available in Various Sizes

ARCTIC MX-4 is available in sizes ranging from 2 to 45 grams. Resealable packaging prevents the paste from drying out.

Long-lasting Durability

Compared to metal or silicone thermal pastes, you don't have to make any compromises with the MX-4: once applied, it lasts up to 8 years.

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.
