Product description
High 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, ensuring 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 sapplications that require thermal transmission.
Easy application
Thanks to its consistency, MX-4 is easy to apply, even for beginners. The video in the picture gallery 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.
100 % original through Authenticity Check
To ensure that your paste is genuine, there is the ARCTIC Authenticity Check. This allows every product to be reliably verified. A counterfeit offers neither the performance nor the durability of the original ARCTIC pastes.
