Alphacool Eisfrost Xtreme Liquid Metal Thermal Paste vs EKWB EK Thermal PAD F 1.5mm: Comparison
Alphacool Eisfrost Xtreme Liquid Metal vs EKWB EK Thermal PAD F 1.5mm electrical conductivity compared
They are built to different briefs, and electrical conductivity shows it, Alphacool Eisfrost Xtreme Liquid Metal Conductive against EKWB EK Thermal PAD F 1.5mm Insulating. Paste segment is not the same on both, Liquid Metal on the Alphacool Eisfrost Xtreme Liquid Metal versus Pad on the EKWB EK Thermal PAD F 1.5mm.
Who each one is for
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. It is not the one for aluminum coolers or any aluminum contact surface, which liquid metal will corrode. The EKWB EK Thermal PAD F 1.5mm is the one to take for DIY water block rebuilds needing a 1.5mm gap-filler pad, though it is not built for CPU/GPU direct-die paste application. It is equally the pick for replacing worn factory thermal pads on EK full-cover water blocks with a 120x16mm contact strip. It is the wrong buy for builds needing a higher-conductivity performance paste rather than a gap-filler pad. 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 EKWB EK Thermal PAD F 1.5mm (6.4/10): A reusable replacement pad sized for EK water blocks, a practical maintenance item rather than a performance pick.
