Alphacool Eisfrost Xtreme Liquid Metal Thermal Paste vs ID-Cooling Frost X45: Comparison

Alphacool Eisfrost Xtreme Liquid Metal vs ID-Cooling Frost X45 electrical conductivity compared

Electrical conductivity is the dividing line, Alphacool Eisfrost Xtreme Liquid Metal Conductive against ID-Cooling Frost X45 Insulating. Recommended use is not the same on both, High-end CPU/GPU, including overclocking; also suited to Delidded-Direct-Die use... on the Alphacool Eisfrost Xtreme Liquid Metal versus High-end CPU/GPU on the ID-Cooling Frost X45. They differ on density too, 6.44 g/cm3 on the Alphacool Eisfrost Xtreme Liquid Metal versus 2.8 g/cm3 on the ID-Cooling Frost X45. Paste segment is not the same on both, Liquid Metal on the Alphacool Eisfrost Xtreme Liquid Metal versus Standard Paste on the ID-Cooling Frost X45.

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. Take the ID-Cooling Frost X45 for enthusiasts and overclockers who want flagship-adjacent numbers without paying flagship prices. It is the wrong buy for builders who specifically want an established brand name over a value pick, TFX or Kryonaut carry more brand recognition. 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 ID-Cooling Frost X45 (8.8/10): one of the best-performing pastes on air cooling in independent testing, though its thick consistency takes practice to spread well.
