Corsair XTM70

XTM70 is Corsair's top-tier thermal compound, despite a reputation online as a "liquid metal" product it is actually a hybrid, non-conductive formula that Corsair explicitly markets as its most advanced standard paste for high-TDP CPUs and GPUs.

Corsair does not officially disclose a specific W/mK figure for XTM70, marketing it instead through its position at the top of the TM30-TM50-XTM70 lineup rather than a direct numeric claim. XTM70 uses a hybrid, metal-oxide-adjacent formula that Corsair explicitly confirms is non-electrically-conductive, a notable and common point of buyer confusion given online chatter that mistakenly labels it liquid metal. The compound ships with an applicator stencil designed to help achieve consistent, even coverage, reflecting its positioning for high-TDP chips where application precision matters more. Despite online rumors, Corsair's own product page confirms XTM70 is non-conductive, meaning it carries none of the short-circuit or corrosion risk associated with true liquid metal compounds like Thermal Grizzly Conductonaut. Corsair does not publish a specific reapplication interval for XTM70; buyers should treat it as suited to sustained high-end and extreme-overclocking use similar to other flagship pastes in this catalog. Against Thermal Grizzly Conductonaut also in this catalog, XTM70 is genuinely a non-conductive paste despite its "liquid metal" reputation, making it a much safer choice than true liquid metal for builders who mistakenly conflate the two products when shopping.
