ARCTIC ACTCP00024A MX-4 Thermal Compound CPU for All Coolers, Thermal Interface Material 

 Composed of carbon micro-particles which lead to an extremely high thermal conductivity. It guarantees that heat generated from the CPU or GPU is dissipated efficiently. With excellent temperature reduction performance, the MX-4 is ideal for CPU and GPU cooling, and other applications between power semiconductor components and heatsinks. The MX-4 is metal-free and non-electrical conductive which eliminates any risks of causing short circuit, adding more protection to the CPU and VGA cards. In contrast to metal and silicon thermal compound, the MX-4 doesn't compromise over time. Once applied, you do not need to apply it again as it will last at least for 8 years.
