PWM controller for 12 V fans and pumps

This Westinghouse unit delivers a 4-pin PWM signal that lets you dial any 12 V four-wire fan or water pump from 0 to 100 percent with a front-panel knob. It draws power from a USB-C port, so it suits DIY cooling builds, small-form-factor rigs, or bench testing where a motherboard header is unavailable. The included five-way splitter hub lets one controller drive several fans at once.

Sustained-load behaviour with boost circuit

A built-in DC-DC boost stage converts the 5 V USB input to a stable 12 V output, keeping voltage steady when multiple fans spin continuously. The onboard PWM generator maintains the chosen duty cycle without drift during long runs, so flow and noise stay predictable whether the loop runs for minutes or hours. No external 12 V brick is required.

Metal chassis, USB-C power and hub wiring

The controller housing is metal with an Art Deco finish, giving a rigid feel and helping dissipate heat from the boost circuitry. A single USB-C cable supplies both power and the 5 V source for the boost converter, reducing cable clutter. The bundled five-way hub uses standard 4-pin connectors, so each attached fan retains its own tachometer wire for monitoring.

Questions about this item

How much heat or noise does the 12V PWM controller add when running fans all day?

The controller itself has no moving parts, so it adds no audible noise and negligible heat while regulating 12V fans from 0 to 100 percent speed.

What must I already own to power and connect this Westinghouse controller?

You need a USB-C power source that can supply 5V and 12V four-pin PWM fans or a water pump to plug into the included 5-way hub.

Will the 4-pin 5-way hub work with the older 3-pin fans I still have?

The hub is designed for 4-pin 12V PWM fans; 3-pin fans can be connected but will run at full speed without PWM control.
