Alphacool Eisfrost Xtreme Liquid Metal Thermal Paste vs PrimoChill Ultra Extreme XR-m Thermal Pad: Comparison

Alphacool Eisfrost Xtreme Liquid Metal vs PrimoChill Ultra Extreme XR-m Thermal Pad: the electrical conductivity difference

Electrical conductivity is the dividing line, Alphacool Eisfrost Xtreme Liquid Metal Conductive against PrimoChill Ultra Extreme XR-m Thermal Pad Insulating. There is a split on recommended use as well, High-end CPU/GPU, including overclocking; also suited to Delidded-Direct-Die use... on the Alphacool Eisfrost Xtreme Liquid Metal versus GPU VRM/MOSFET Cooling, Case-Mod Builds on the PrimoChill Ultra Extreme XR-m Thermal Pad. There is a split on paste segment as well, Liquid Metal on the Alphacool Eisfrost Xtreme Liquid Metal versus Pad on the PrimoChill Ultra Extreme XR-m Thermal Pad.

Which should you buy, Alphacool Eisfrost Xtreme Liquid Metal or PrimoChill Ultra Extreme XR-m Thermal Pad?

Take the Alphacool Eisfrost Xtreme Liquid Metal for experienced overclockers with copper or nickel-plated-copper cooler bases wanting maximum conductivity. The same goes for delidded, direct-die CPU/GPU setups where liquid metal is the established choice. Avoid it for aluminum coolers or any aluminum contact surface, which liquid metal will corrode. it is the wrong buy for standard CPU IHS-to-cooler applications where a conventional paste is simpler. It is equally the pick for GPU VRM/MOSFET cooling and case-mod builds needing a cuttable, shapeable thermal pad. It is not the one for anyone needing a spreadable liquid compound rather than a solid cut-to-size sheet. Our rating of the Alphacool Eisfrost Xtreme Liquid Metal (7.8/10): A gallium-alloy liquid metal aimed at high-end builds, bundled with application swabs to ease the learning curve. Our rating of the PrimoChill Ultra Extreme XR-m Thermal Pad (6.9/10): A cuttable high-conductivity sheet aimed at GPU VRM and case-mod cooling, from a brand known for water-cooling components.
