Alphacool International GmbH, based in Braunschweig, Germany, is a pioneer in the field of PC water-cooling technology. With one of the most comprehensive product portfolios in the industry and more than 20 years of experience, Alphacool is expanding its professional GPU cooling lineup with new high-performance water coolers designed for Nvidia RTX Pro Blackwell and Amd Radeon AI Pro graphics cards.


The new Es GPU coolers are available for the Nvidia RTX Pro 4000 Blackwell, RTX Pro 4500 Blackwell, RTX Pro 6000 Blackwell, and Amd Radeon AI Pro R9700.

You can easily check the compatibility of your graphics card using our GPU Configurator: https://gpu.alphacool.com


A key feature of the new cooling solutions is their uncompromising 1-slot design. Each cooler occupies only the PCIe slot used by the graphics card itself, making the design particularly attractive for dense workstations, AI, rendering, simulation, and multi-GPU configurations where every expansion slot matters.


At the heart of each cooler is a chrome-plated copper cooling block, engineered for efficient heat transfer and long-term durability. The Jet Engine cooling technology is used to provide high-performance coolant flow across the critical thermal areas of the GPU.

The terminal is manufactured from brass and chrome plated, providing a robust connection interface with 2x G1/4" ports for flexible integration into professional liquid-cooling loops.
A carbon-fibre front plate gives the cooler a distinctive technical appearance while keeping the construction lightweight. The design is completed by an aluminium backplate, providing additional support and a clean finish.
