PrimoChill Ultra Extreme XR-m Thermal Pad

The Ultra Extreme XR-m is PrimoChill's thermal interface pad rather than a paste, sold as a cuttable sheet aimed at GPU VRM and MOSFET cooling as well as custom case-mod builds needing a flexible, shapeable TIM.

PrimoChill officially rates the Ultra Extreme XR-m at 17.0 W/mK, one of the highest officially-published figures in this entire catalog, reflecting the different physics of a solid silicone pad versus a spreadable grease. The pad uses a silicone-based solid formulation, sold in 60x50mm sheets at multiple thicknesses so builders can cut it to the exact shape their VRM or MOSFET layout requires. Unlike every grease-based product in this catalog, the XR-m is applied by cutting the sheet to size and placing it between surfaces, avoiding spreading tools or syringes entirely. The pad is electrically non-conductive, carrying no short-circuit risk, and its solid form avoids the spillage or migration risk associated with liquid or paste compounds. As a solid sheet, the Ultra Extreme XR-m avoids pump-out entirely, a structural advantage shared with other pad-based products in this catalog like Innovation Cooling IC Graphite and Honeywell PTM7950. Against Fujipoly Extreme X-e Thermal Pad also in this catalog, PrimoChill's officially rated 17.0 W/mK exceeds Fujipoly's 11.0 W/mK, making the XR-m the higher-performance choice for buyers who specifically need pad-based cooling at maximum conductivity.
