The Alphacool ES water cooler was specifically designed for professional use in performance-optimized workstation and server environments. Its compact 1.5-slot design and intelligent port positioning offer maximum cooling performance in a confined space. Material & Durability: Carbon and chrome-plated copper Alphacool relies on an innovative material mix for maximum reliability: The top surface is made of lightweight, extremely durable carbon fiber , which significantly reduces the overall weight. The heatsink itself is made entirely of chrome-plated copper . This chrome plating is significantly harder than conventional nickel plating and offers superior protection against corrosion and mechanical stress - ideal for low-maintenance 24/7 continuous operation . Maximum cooling through active backplate A particular highlight is the active backplate , which also features a chrome-plated copper base and a carbon fiber backplate. A unique, internal double-nipple system connects the main cooler directly to the backplate for efficient heat dissipation from both sides.
