High Performance Thermal Compound for the Enthusiast The Arctic Cooling MX-2 is a high thermal conductivity and low thermal resistance compound for components that require optimum thermal dissipation. It is ideally suited for use in CPU, GPU cooling and other applications between power semiconductor components and heat sinks where thermal conductivity is a major factor. Safe to apply anywhere Since the MX-2 does not contain any metal particles, there are no problems regarding electrical conductivity or capacitance. Unlike other silver and copper compounds, MX-2 ensures that contact to electrical traces, pins and leads cannot result in any damage. Durability With MX-2 no curing and no bleeding of the compound is possible. In contrast to other products, this compound does not show decreasing performance over time and therefore does not need to be reapplied. It is also durable for at least 8 years.
