Features 1. Supports dual-voltage input (DC 12V/24V) for strong compatibility and hassle-free use 2. Three independent 4-wire outputs for synchronized, intelligent control of three fans 3. Built-in high-precision temperature control module that detects temperature in real time and automatically adjusts fan speed 4. Streamlined design with simple wiring for quick and easy setup 5. DIP switch for setting temperature thresholds—intuitive operation with no debugging required Product Description This speed controller supports 12V/24V 5A input (current is determined by the connector’s current-carrying capacity), with one input and three synchronized outputs. It is compatible only with Intel-standard 4-wire fans (2-wire and 3-wire fans are not supported). It uses pure PWM signal speed control to prevent stuttering and abnormal noises caused by intermittent power supply. When the blue wire is connected to the negative terminal, the fan operates at minimum speed (approximately 20%, without shutting down) Parameter Operating Voltage: DC 12V, 24V Control Method: Temperature-controlled speed regulation Maximum Output Current: 5A Instructions for Use This speed controller is designed to enter minimum speed at a fixed temperature of approximately 23°C. The maximum temperature for maximum speed is set via DIP switches within the range of 43–70°C; When all DIP switches are off, the maximum speed temperature is 43°C, and the fan operates at stepless speed control between 23°C and 43°C; When the first switch is set to the ON (0N) position, the maximum speed temperature is 52°C, and the fan operates at stepless speed control between 23°C and 52°C; When the first switch is off and the second switch is on, the maximum speed temperature is 61°C, and the fan operates at stepless speed control between 23°C and 61°C; With both channels 1 and 2 activated, the maximum operating temperature is 70°C, and the fan speed varies continuously between 23 and 70°C; The default setting upon shipment is with all switches off.
