Fujipoly Extreme X-e Thermal Pad

The Extreme X-e is Fujipoly's silicone-based thermal interface pad, widely used in case-mod builds as a cuttable universal filler pad for GPU backplates, VRM sections, and chassis heatsink mounting.

Fujipoly officially rates the Extreme X-e at 11.0 W/mK, a solidly documented figure for a pad-based thermal interface material, though notably lower than PrimoChill's Ultra Extreme XR-m at 17.0 W/mK also in this catalog. The pad uses a silicone-based solid formulation, sold in sheet sizes like 100x15mm at multiple thicknesses to suit different gap-filling needs. Like other pad-based products in this catalog, the Extreme X-e is applied by cutting the sheet to the required size and placing it between surfaces rather than spreading a liquid compound. The pad is electrically non-conductive, carrying no short-circuit risk, and its solid form avoids the migration and spillage concerns of liquid or paste compounds. As a solid sheet, the Extreme X-e avoids pump-out entirely, a durability advantage shared with other pad-based products in this catalog. Against PrimoChill's Ultra Extreme XR-m also in this catalog, Fujipoly's officially rated 11.0 W/mK sits below PrimoChill's 17.0 W/mK, though Fujipoly's smaller sheet format may suit narrower gap-filling applications better.
