Details
The Alphacool ES 90° GPU Terminal is a replacement terminal in chrome-plated brass that turns the connections of a compatible Alphacool GPU water block by 90°, with two G1/4 threads. Alphacool lists it for ES GPU water blocks whose terminal is held by three screws, Core GPU water blocks for the GeForce RTX 50XX and Radeon RX 90XX series, and all Eisblock GPU water blocks.

Space-saving connection
The terminal allows space-saving and flexible integration of a compatible GPU water cooler into an existing water cooling loop. Its 90° angled design improves tube routing, which makes installation particularly easy in server cases and workstation PCs, where space is often limited.
Built to last
The terminal is made of high-quality chrome-plated brass. Alphacool says it offers excellent resistance to scratches and chemical influences, and that its robust construction ensures long-lasting, reliable use.
Compatibility
Compatibility requires the terminal to be secured to the cooling block with three screws. Alphacool's data sheet lists:
- ES GPU water blocks with a terminal secured to the cooling block using three screws
- Core GPU water blocks for the GeForce RTX 50XX and Radeon RX 90XX series
- All Eisblock GPU water blocks
Installation
The terminal goes on with the two O-rings and the screws from the box; installation must follow Alphacool's manual. Each G1/4 thread takes a fitting for your tube size, which is not in the box. Do not tighten the G1/4 threads beyond 1.00 Nm.
