Arctic MX-2

MX-2 is Arctic's older, budget-tier carbon-based compound, largely superseded in Arctic's own lineup by MX-4 and MX-6 but still sold as a discounted, entry-level option for cost-sensitive builds.

Arctic does not prominently publish a precise current W/mK figure for MX-2 on modern spec listings; older product literature cited a figure around 5.6 W/mK, Arctic does not publish a thermal conductivity figure for MX-4 either. MX-2 uses the same carbon-based category as its MX-4 and MX-6 successors, keeping the compound non-conductive and non-capacitive. The paste has a workable consistency suited to standard spreading methods, similar in application approach to MX-4 but at a lower price point. MX-2 remains non-conductive and non-capacitive, carrying no short-circuit risk from standard application. Arctic does not publish a specific reapplication interval for MX-2; as a legacy budget product, buyers should apply typical multi-year paste durability expectations cautiously and verify current documentation. Against Arctic MX-4 also in this catalog, MX-2 sits clearly below it in both price and rated conductivity, making MX-4 the better all-around choice unless MX-2's lower price is the deciding factor.
