Alphacool ES Reservoir DDCzero 1U s pumpou (14571)

Server and workstation water cooling often demands compact, reliable components that fit into tight 1U chassis without sacrificing performance. The Alphacool ES Reservoir DDCzero 1U with Pump answers that call, combining a reservoir and a DDCzero pump in a single acetal (POM) unit engineered for space-constrained builds. Unlike typical cylindrical reservoirs, this flat, low-profile design mounts directly into 1U server racks or small form factor cases, providing a stable coolant supply and consistent flow where every millimeter counts.

Highlights

• Integrated DDCzero pump and reservoir in a 1U-compatible form factor
• Durable acetal (POM) construction for long-term reliability
• Four G1/4" ports: inlet, outlet, fill, and drain for flexible loop routing
• Low power consumption of just 3 W with a standard 3-pin fan connector
• Quiet operation with a maximum head pressure of 0.9 m and flow rate up to 100 L/h

In daily use

Installing the ES Reservoir DDCzero is straightforward thanks to its screw-on mounting system. The four G1/4" threaded ports allow you to configure the loop to suit your layout: use the inlet and outlet for the main flow, the fill port for easy topping up, and the drain port for maintenance. The DDCzero pump runs on 12 V DC and connects to any standard 3-pin fan header, making it compatible with most motherboards and fan controllers. Its modest power draw and efficient design help keep system noise and heat to a minimum, which is essential in server environments.
