Product details

Alphacool expands its Enterprise series with the latest 1-slot water coolers for the current Nvidia GeForce RTX generation. These solutions are specifically designed for use in server enclosures and workstations, enabling efficient cooling even in densely packed systems.

By employing a thin yet extremely robust carbon plate, these coolers have been designed as 1-slot units without compromising the integrity of the copper block. Paired with rear-placed brass connectors, multiple coolers can be easily stacked on top of each other or side by side within a server case. This thoughtful design saves space, simplifies tubing, and allows for seamless integration into the water circuit.

All water-bearing parts are made from high-quality copper, which offers nearly twice the thermal conductivity of aluminum. Additionally, the copper is chrome-plated rather than nickel-plated, providing extra protection for the cooler. Chrome plating is more resistant to acids, scratches, and other damage, effectively preventing the chipping of coatings.

The GPU water cooler has undergone a complete technical overhaul. To optimize cooling performance, the spacing between the cooler and the components on the PCB was redefined and tested. The water flow was simulated using state-of-the-art software and validated through practical trials. These extensive tests led to improvements in the cooler base and nozzle, ensuring the best possible cooling performance for the new Nvidia GeForce RTX generation.

The disruptive RGB cable of the Alphacool core lighting is permanently connected to the cooler. If you want to do without the lighting, you can unscrew the RGB bar and cable. However, this means unnecessarily breaking the warranty seal, which is unique in the test field. (1) Alphacool uses a black, tight O-edge with a slight notch to guide the cable feed-through cleanly on the cover...
