Details
The Alphacool ES RTX 6000 Pro Server Edition 1-Slot-Design is a GPU water block for two cards. They are the Nvidia RTX PRO 6000 Blackwell Server Edition and the Nvidia RTX PRO 6000 Blackwell Max-Q Workstation Edition, both with 96GB GDDR7. It is a 1-slot cooler for dense rack installations, with both G1/4 ports on the rear, and the aluminum backplate is in the box.

Made for servers
This ES 1-Slot GPU water cooler was specifically designed by Alphacool for professional use in performance-optimized server environments. With its compact 1-slot design and well-conceived port placement, Alphacool says it meets the highest demands for cooling performance, reliability, and ease of installation. That holds especially in dense rack installations with limited space. Alphacool calls the cooler the ideal solution for enterprise applications where performance, reliability, and efficient space management are paramount.
Carbon top and chrome-plated copper
The cooler's top surface is made of lightweight, durable carbon fiber. Alphacool says this significantly reduces the cooler's weight compared to conventional solutions. At the same time, the matte carbon finish provides what it describes as a subtle, high-quality look, both functional and elegant. The cooling block itself is made entirely of chrome-plated copper. Alphacool says chrome plating is significantly harder and more durable than conventional nickel plating, and that it reliably protects against corrosion, scratches, and mechanical damage. It calls that ideal for long-term, 24/7 operation.
Ports on the rear
The cooler's inlet and outlet ports are conveniently located on the rear. Alphacool says this connection architecture simplifies tubing and integration into existing cooling loops, even in very compact server chassis.
Water flow
An optimized cooling channel structure takes the heat from the GPU, VRAM, and voltage regulators, and Alphacool says it ensures particularly efficient heat dissipation. In its words, precise channeling within the cooler ensures a uniform water flow across all relevant components. Alphacool says the solid copper base guarantees optimal heat absorption and transfer, and that the robust chrome plating prevents peeling or damage under thermal stress.
What the loop needs
The cooler has two G1/4 connections with brass threads, both on the rear. Each takes one of the compression fittings for your tube size, which are not in the box. Alphacool gives 1.00 Nm as the maximum torque for the G1/4 thread. There is no lighting to connect. The backplate, the thermal pads, thermal grease, a putty tool, the screws and the PCIe bracket come with the cooler.
