Common Applications
The SPD10-S is a 10W DC12V PWM water cooling pump intended for single-loop custom builds. It delivers up to 450L/H of flow and 3m of static head at a maximum of 4000 RPM, with PWM input allowing speed regulation directly from a motherboard or fan controller header. The body uses POM and PMMA with an aluminum-alloy heatsink to dissipate motor heat, and inlet/outlet ports are G1/4 to accept any standard fitting set. The footprint is approximately 70 x 70 x 50mm so the pump can sit inside small form-factor cases or be attached to a bracket on a 120mm fan grille. The housing includes 5mm lighting slots that accept a separate LED for accent illumination; an LED is not bundled.
Frequently Asked Questions
Q: What are the rated voltage, power, and PWM behavior?
A: The SPD10-S draws up to 10W from DC12V. PWM duty cycle controls pump speed from idle up to roughly 4000 RPM through a standard 4-pin connector.
Q: What flow and head can it sustain?
A: Free-flow rating is up to 450L/H and the maximum static head is 3m. Real-loop flow falls below the free-flow number once a radiator, CPU block, and fittings are added.
Q: What ports and dimensions are used?
A: Inlet and outlet are G1/4 threaded. The pump body measures roughly 70 x 70 x 50mm so it fits behind a 120mm fan footprint.
Q: Does it include lighting?
A: The housing has 5mm LED slots but no LED is included. Add a separate 5mm LED or use a Barrow lighting strip.
Q: Can the SPD10-S replace a D5 or DDC pump?
A: For a single CPU plus one radiator the SPD10-S is sufficient, but a multi-radiator or GPU-plus-CPU loop benefits from the higher head pressure of a 17W DDC or D5-class pump.
