Alphacool Eisfrost Xtreme Liquid Metal vs Laird (Laird Performance Materials) Laird: which one fits your build
Take the Alphacool Eisfrost Xtreme Liquid Metal for experienced overclockers with copper or nickel-plated-copper cooler bases wanting maximum conductivity. It also earns its place with delidded, direct-die CPU/GPU setups where liquid metal is the established choice. It is the wrong buy for aluminum coolers or any aluminum contact surface, which liquid metal will corrode. Buy the Laird (Laird Performance Materials) Laird for M.2 SSD heatsink contact and laptop GPU/VRAM cooling, though it is not the pick for high-power desktop CPU/GPU dies needing >3 W/mK. 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 Laird (Laird Performance Materials) Laird (6.2/10): an industrial-grade gap filler pad from an established materials brand, cuttable to size for M.2 and laptop use.
