Common Applications

The SPB17-S V2 is a 17W DC12V DDC-class water cooling pump aimed at custom loops that include a GPU block, multiple radiators, or restrictive distribution plates. Free-flow rating reaches roughly 960L/H with a maximum head of about 5.5m at 4000 RPM, giving enough pressure to push coolant through a CPU plus single-GPU loop without stalling. Speed is set through PWM input or through the manual potentiometer dial on the pump body, so the pump can run at low duty in idle and ramp up under load. The aluminum-alloy shell and acrylic top double as a passive heatsink for the motor, and a 5V 3-pin LRC 2.0 addressable RGB ring lights the top. Inlet and outlet are G1/4 threaded. The pump ships without an external RGB controller.

Frequently Asked Questions

Q: What flow, head, voltage, and power does the SPB17-S V2 deliver?

A: It draws up to 17W from DC12V, delivers up to about 960L/H free flow, reaches roughly 5.5m of static head, and tops out near 4000 RPM.

Q: How is speed controlled?

A: Through a standard 4-pin PWM header from a motherboard or fan controller, or via the manual rotary potentiometer on the pump body, which sets a fixed speed when PWM is not used.

Q: What RGB protocol does the SPB17-S V2 use?

A: 5V 3-pin addressable RGB (Barrow LRC 2.0). It is wired identically to common 5V ARGB headers - do not connect it to a 12V RGB header or the LED ring will be damaged.

Q: What is in the box, and is a controller included?

A: One SPB17-S V2 pump with PWM cable and 5V ARGB cable. An external LRC 2.0 controller is not included; the ARGB lead can also be plugged directly into a motherboard 5V 3-pin ARGB header.

Q: Is this pump truly a DDC clone, and do DDC tops fit it?

A: It uses DDC-class hydraulics and a similar mounting pattern, but the threaded body design works specifically with Barrow's threaded reservoirs (for example the TKDDCG50 series). Generic DDC tops are not guaranteed to seal.
