The Alphacool ES 1-Slot GPU water cooler for the RTX Pro 4000 Blackwell was specifically developed for professional use in performance-optimized server environments. With its compact 1-Slot design and carefully engineered port positioning, it meets the highest standards in cooling performance, reliability, and ease of installation ? especially in dense rack installations with limited space. The top of the cooler is made from lightweight, durable carbon. This significantly reduces the overall weight compared to conventional solutions. At the same time, the matte carbon finish provides a subtle, high-quality appearance ? functional and elegant in equal measure. The cooling block itself is made entirely of chrome-plated copper. The chrome plating is considerably harder and more durable than traditional nickel plating, offering reliable protection against corrosion, scratches, and mechanical impact ? ideal for long-term 24/7 operation. The inlet and outlet ports are positioned on the rear of the cooler to save space. This connection layout simplifies tubing and integration into existing cooling loops, even in very compact server chassis. An optimized internal channel structure ensures highly efficient heat dissipation from the GPU, VRAM, and voltage regulators. The targeted channel routing inside the cooler guarantees uniform water flow across all critical components. The solid copper base ensures optimal heat absorption and transfer. The robust chrome plating prevents flaking or damage under thermal stress.
