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. It also earns its place with 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 PCCooler EX90 is the one to take for overclockers and high-TDP builds wanting PCCooler's flagship-tier number. It is the wrong buy for buyers who want a paste with a longer independent review history, TFX or Kryonaut are more established. 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 PCCooler EX90 (7/10): PCCooler's flagship compound offers strong published numbers, though it lacks the independent review base of bigger brands.
