Product Features
1. Using PWM technology, this speed controller enables precise control of fan speed.
2. Supports simultaneous connection of two 4-wire fans, allowing for synchronized control of both fans.
3. Users can manually adjust fan speed to set their desired speed.
4. Includes a reverse connection protection circuit to effectively prevent damage caused by incorrect wiring.
5. Real-time LED status display: the faster the speed, the brighter the light.

Product Description
This module is specifically designed for standard Intel 4-wire fans. It outputs a pure PWM speed control signal; fans must have their own speed control circuitry, and 2-wire or 3-wire fans are not compatible. Unlike PWM speed control via power supply, this method avoids abnormal noise and stuttering caused by intermittent power supply, ensuring smoother fan operation. The blue and black wires are the speed control terminals (corresponding to pins 1–4): A short circuit sets the minimum speed; no short circuit sets the maximum speed. This module is compatible only with standard Intel 4-wire fans.
