Common Applications

The CP-DWPB-X is a heavy-duty PWM water-cooling pump aimed at large custom loops that chain multiple GPU blocks, distribution plates, and several radiators in series. The motor is fed by a 12V 5A rail with a 4-pin Molex power input and a separate PWM data line that returns a tach signal, so motherboard fan headers can ramp pump speed in step with thermal load. The body is solid black POM with a metal armor sleeve that doubles as heat dissipation for the stator, and the pump is rated at 1400 L/H peak flow rate. Port threads are standard G1/4 BSPP.

Frequently Asked Questions

Q: What is the peak flow rate?

A: 1400 L/H at full speed, measured at zero head.

Q: How is the pump powered and controlled?

A: A 4-pin Molex connector supplies 12V at up to 5A; a separate PWM data plug gives the motherboard fan header full speed control with tach feedback.

Q: What body and port standard does the pump use?

A: The body is solid POM with a metal armor sleeve. Inlet and outlet ports are G1/4 BSPP, the same thread used across mainstream blocks and reservoirs.

Q: Can this pump drive a large multi-radiator loop?

A: Yes. It is rated for the kind of heads produced by chained 360/420 radiators, several GPU blocks and a distribution plate. For dual-system loops, Bykski recommends running two pumps in series.

Q: Is it safe to run dry?

A: No. Like every centrifugal water-cooling pump, the bearing and rotor are coolant-lubricated. Never power the pump before the loop is filled and purged.
