Pump Reservoir 440mL

The Corsair iCUE LINK XD6 RGB ELITE is a combined pump and reservoir unit designed for custom liquid-cooling loops. Its 440mL capacity suits builders who want a single component to handle coolant storage and circulation. The integrated iCUE LINK connector reduces cable count by linking directly to a System Hub. Enthusiasts who prefer a unified RGB ecosystem will appreciate the native software control.

Build Quality and Mounting

An aluminium pump housing and transparent nylon reservoir form the core structure, while an anti-vortex mesh inside the reservoir promotes steady flow. Rubberised mounts isolate vibration for quieter operation. The package supplies both 120mm and 140mm fan brackets plus an L-bracket, giving flexibility for radiator placement. Three G1/4 stop plugs and multiple inlet ports support varied loop routing. A 600mm iCUE LINK cable and USB-C cable connect the unit to the hub and motherboard.

Upgrade Path and Value

This unit replaces a separate pump, reservoir and RGB controller, consolidating three items into one. The onboard coolant temperature sensor enables automatic speed curves through iCUE software, removing the need for an external sensor. Builders moving from a basic D5 or DDC pump gain integrated lighting and fill-port convenience. Loops that already use standard G1/4 fittings connect without adapters. The jump is most worthwhile when simplifying a new build or overhauling an older loop that lacks temperature-based control.

Questions about this item

Does the iCUE LINK interface on the XD6 RGB ELITE cap the number of devices I can chain?

The iCUE LINK ecosystem uses universal connectors that plug into a single port on the iCUE LINK System Hub, which is sold separately.

What mounting hardware is included to fit the pump reservoir in my case?

The box includes a 120mm fan mounting bracket, a 140mm fan mounting bracket, an L-bracket, and a rubberized mounting system to reduce vibrations.

How do I install the reservoir fill port correctly, and what step do people often miss?

Use the integrated fill port on the transparent nylon reservoir; the step often missed is installing the three included G1/4 stop plugs into any unused inlet ports before filling.
