Alphacool Eisfrost Xtreme Liquid Metal Thermal Paste vs Thermalright TF8: Comparison
Alphacool Eisfrost Xtreme Liquid Metal vs Thermalright TF8 electrical conductivity compared
The first real difference is electrical conductivity: Alphacool Eisfrost Xtreme Liquid Metal Conductive against Thermalright TF8 Insulating. Applicator included is not the same on both, None on the Alphacool Eisfrost Xtreme Liquid Metal versus Spatula on the Thermalright TF8. They differ on density too, 6.44 g/cm3 on the Alphacool Eisfrost Xtreme Liquid Metal versus 2.9 g/cm3 on the Thermalright TF8. There is a split on paste segment as well, Liquid Metal on the Alphacool Eisfrost Xtreme Liquid Metal versus Standard Paste on the Thermalright TF8.
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 the wrong buy for aluminum coolers or any aluminum contact surface, which liquid metal will corrode. The Thermalright TF8 is the one to take for experienced builders comfortable spreading stiff paste, though it is not built for anyone who can't verify which TF8 batch they are buying and beginners who want an easy thin spread. It is equally the pick for buyers who can confirm pre-2025 stock and want a dense, high-performing paste. 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 Thermalright TF8 (6.6/10): A high-density filler paste from an older TF-series batch; buyers should be aware a 2025 formula change was flagged by independent testers.
