The Alphacool ES 1-Slot GPU water cooler for the RTX Pro 4000 Blackwell was specifically designed for professional use in performance-optimized server environments. With its compact 1-slot design and well-conceived port placement, it meets the highest demands for cooling performance, reliability, and ease of installation – especially in dense rack installations with limited space.

The cooler's top surface is made of lightweight, durable carbon fiber. This significantly reduces the cooler's weight compared to conventional solutions. At the same time, the matte carbon finish provides a subtle, high-quality look – both functional and elegant. The cooling block itself is made entirely of chrome-plated copper. Chrome plating is significantly harder and more durable than conventional nickel plating and reliably protects against corrosion, scratches, and mechanical damage – ideal for long-term, 24/7 operation.

The cooler's inlet and outlet ports are positioned on the rear to save space. This port layout simplifies tubing and integration into existing cooling loops, even in very compact server chassis. An optimized cooling channel structure ensures highly efficient heat dissipation from the GPU, VRAM, and voltage regulators. Precise channel routing within the cooler guarantees a uniform water flow across all relevant components.

The solid copper base ensures optimal heat absorption and transfer. The robust chrome plating prevents peeling or damage under thermal stress.

The Alphacool ES 1-Slot GPU water cooler for Nvidia RTX Pro 4000 Blackwell is the ideal solution for enterprise applications where performance, reliability, and efficient space management are paramount.
