The Arctic MX-4 compound is 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 quickly and efficiently. Superb in performance, MX-4 is the best companion for over clockers and enthusiasts. With an ideal consistency, the MX-4 thermal compound is very easy to use. even for beginners. It does not contain any metallic particles so electrical conductivity would not be an issue. Unlike silver and copper compound, it ensures that contact with any electrical pins would not result in damage of any sort. It contrast to metal and silicon thermal compound, the performance of MX-4 does not compromise over time. Once applied, you do not need to apply it a second time as it will last at least for 8 years. A high performance thermal compound perfect for system builders, there's no surprise that the MX-4 exceeds your expectations.
