Alphacool launches the ES GeForce RTX 5090 Gaming 1-Slot Design, a slim single-slot waterblock for the GIGABYTE GeForce RTX 5090 GAMING and WINDFORCE variants. The waterblock reduces the thick 3-slot plus thick graphics cards to a sleek single-slot. Designed for server and workstations, the ES GeForce RTX 5090 Gaming 1-Slot Design has rear-mounted inlet and outlet ports.

The Alphacool ES GPU coolers have been specially developed for use in server cases and workstations. Thanks to their slim 1-slot design and rear-mounted connectors, they can be easily integrated into densely equipped systems and stacked without blocking adjacent PCIe slots. This simplifies tubing and enables a space-saving, efficient integration into the water loop.

As always, Alphacool relies on high-quality materials. The front and backplate are made of a lightweight yet robust carbon plate, while all water-bearing elements are manufactured from chrome-plated copper. This combination guarantees top quality, durability, and additional protection for the cooling block.

Technically, the cooler has been completely redesigned. Using state-of-the-art simulation software and extensive testing, both the cooling base and jet plate have been optimized – ensuring maximum cooling performance for the latest Nvidia GeForce RTX generation.

Alphacool ES GeForce RTX 5090 Gaming 1-Slot Design Compatibility:
GIGABYTE GeForce RTX 5090 GAMING OC 32G
GIGABYTE GeForce RTX 5090 WINDFORCE 32G
GIGABYTE GeForce RTX 5090 WINDFORCE OC 32G
