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 overclockers and enthusiasts.
It does not contain any metallic particles so electical 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.
In 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 suprise that the MX-4 exceeds your expectations for its low price tag.
