Arctic MX-4 4gm (incl. Spatula) Carbon Based Thermal Paste  (4 g 3.8 W/mK)

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 creates a surface conducive to extremely high thermal conductivity, guaranteeing fast and efficient heat transfer from the CPU or GPU to the cooler. Unlike with liquid metal or pastes containing metal oxide, you don't have to worry about short circuits as the MX-4 itself is not conductive, and using it will not cause corrosion damage.
