Common Applications

The CP-NWD5ST-X is a D5-class pump bonded to a cylindrical reservoir with integrated lighting, intended as the heart of a custom open-loop water cooling system. The D5 motor is rated at 720L/H maximum flow and 4.5 metres maximum head, comfortably covering single-CPU loops, CPU plus GPU loops and most mid-complexity multi-block builds without needing a second pump. The brushless motor with ceramic bearing is rated for continuous-duty operation, and PWM speed control allows the flow-versus-acoustic balance to be tuned from the motherboard fan header. Integrating the pump and reservoir into one part reduces the number of fittings, tube runs and potential leak points in the loop, which makes assembly cleaner and bleeding faster. The G1/4 inlet and outlet ports accept any standard water-cooling fitting, and the standard D5 footprint makes it a drop-in option for most existing D5 combo installations.

Frequently Asked Questions

Q: What is the rated flow and head?

A: 720L/H maximum flow and 4.5 metres maximum head, sufficient for typical single-CPU and CPU plus GPU loops.

Q: Does the pump support PWM speed control?

A: Yes. PWM speed control allows flow rate and acoustics to be tuned from the motherboard fan header.

Q: What thread are the inlet and outlet ports?

A: G1/4 inch, compatible with mainstream water-cooling fittings.

Q: Is this a closed AIO or a component for custom loops?

A: It is a component for open custom loops - you build the loop around it with separate radiator, tubing, fittings and water blocks. It is not a self-contained AIO.

Q: What is the bearing and duty rating?

A: Brushless motor with ceramic bearing, rated for continuous-duty operation under PWM control.
