12V PWM Fan Controller for Six Fans

This 12V PWM fan controller manages up to six 4-pin fans from a single hub. It is built for PC builders who want centralised speed control for gaming rigs or workstation cooling loops. The unit accepts power from a SATA connector or a DC 5.5 × 2.1 mm jack, giving flexibility inside different chassis layouts. A rotary knob provides manual 1–99 % speed adjustment without software.

USB-C PD 3.0 and QC 3.0 Power Input Limits

The hub can also draw power through a USB-C port that supports PD 3.0 and QC 3.0, but total output is capped at 60 W across all connected fans. This ceiling restricts the number of high-current fans you can run simultaneously, especially if each unit draws near the upper end of the PWM range. Builders planning dense radiator stacks should verify per-fan wattage before populating all six headers. The USB-C path is convenient for test benches, yet it cannot exceed the 60 W aggregate limit.

Tool-Free Installation with Common Pitfalls

Installation is tool-free: plug the hub into a SATA or DC jack, connect the USB-C cable for auxiliary power, then attach up to six 4-pin fan headers. The knob adjusts all channels together, so independent zone control is not possible. A frequent issue arises when mixed 3-pin and 4-pin fans are used; 3-pin models may not respond to PWM signals and can run at full speed regardless of knob position. Ensure every fan is 4-pin PWM compatible for proper regulation.

Questions about this item

Which power input version should I choose for my fan setup?

Choose the SATA or DC 5.5×2.1 mm version if your PSU has those connectors; pick the USB-C PD 3.0 QC 3.0 model when you prefer a single Type-C cable and have a compatible charger.

What does the 60 W rating mean once the hub is installed in my PC?

It is the maximum combined power the hub can deliver to all six 4-pin PWM fans, so total fan draw must stay at or below 60 W.

How does the USB-C PD 3.0 QC 3.0 interface cap the hub's performance in practice?

The USB-C port negotiates up to 60 W under PD 3.0 and QC 3.0, so the hub can run six fans at full 99 % PWM only when the charger or host port supplies that power.
