Alphacool Eisfrost Xtreme Liquid Metal Thermal Paste vs Thermal Grizzly Kryonaut: Comparison

What is the difference between Alphacool Eisfrost Xtreme Liquid Metal and Thermal Grizzly Kryonaut?

Electrical conductivity is the dividing line, Alphacool Eisfrost Xtreme Liquid Metal Conductive against Thermal Grizzly Kryonaut Insulating. They differ on recommended use too, 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 Thermal Grizzly Kryonaut. They differ on applicator included too, None on the Alphacool Eisfrost Xtreme Liquid Metal versus Spatula on the Thermal Grizzly Kryonaut. Paste segment is not the same on both, Liquid Metal on the Alphacool Eisfrost Xtreme Liquid Metal versus Standard Paste on the Thermal Grizzly Kryonaut.

Which should you buy, Alphacool Eisfrost Xtreme Liquid Metal or Thermal Grizzly Kryonaut?

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 the wrong buy for aluminum coolers or any aluminum contact surface, which liquid metal will corrode. Take the Thermal Grizzly Kryonaut for extreme overclockers and high-TDP flagship CPU builds. Current guides specifically single this paste out for chips like an Intel Core i9-14900K under sustained heavy load. It also earns its place with enthusiasts who repaste periodically and want the strongest safe option available each time. The small tube size suits this occasional-use pattern. It is not the one for casual or mainstream builds. Arctic MX-6, covered elsewhere on this site, delivers performance within a fraction of a degree at a considerably lower price for typical use. 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 Thermal Grizzly Kryonaut (7.3/10): A long-time enthusiast favorite that performs excellently fresh out of the tube, though multiple reviewers have flagged pump-out on long-term mounts, so periodic reapplication is worth planning for.
