5/12V 4-Wire PWM Fan Temperature Controller PC CPU Cooler Fan Temperature Control Speed Regulation Auto Speed Control PWM 25 kHz

Features1. Compatible with 5V/12V four-wire fans, suitable for a wide range of scenarios2. Automatically adjusts speed based on temperature: quiet at low speeds, efficient cooling at full speed3. Users can customise the activation temperature, activation duty cycle and temperature differential for full speed4. 343 combination modes to suit a variety of different scenarios5. Precise four-wire PWM speed control for quiet and efficient operationSpecificationsProduct Name: Fan Temperature ControllerSupported Fans: 5V/12V standard four-wire PWM fans (does not support 2- or 3-wire fans)Input Voltage: 5–15V (input and output are directly connected; please note the fan’s voltage rating)Fan Current: Less than 2A (for high currents, it is recommended to connect the fan interface directly to the power supply)Fan Connector: MX2.54 3+1P semi-back-to-back (B3 terminal)Standby Power Consumption: 10mW (5V); 25mW (12V)Temperature Sensor: NTC 50K B=3950PWM signal: 25 kHz, Vpp = 5 VTemperature Control Strategy343 combination modesParameter settings: activation temperature, activation ratio, full-speed temperature differential1. Activation temperature: {35, 40, 45, 50, 55, 60, 65} // Default 45 °C2. Start-up percentage: {20, 25, 30, 35, 40, 50, 60} // Default 25°C3. Full-speed temperature differential: {5, 10, 15, 20, 30, 40, 50} // Default 20°CDelayed shutdown: Operation ceases when the temperature drops to 3°C below the start-up temperatureExample: With a start temperature of 45°C, a start percentage of 25% and a full-speed temperature differential of 20°C, the fan will start at 25% when the temperature rises to 45°C, reach full speed once it reaches 65°C (45 + 20), and stop when the temperature drops to 42°C.Package Contents:Temperature-controlled speed regulator × 110 cm epoxy resin probe × 1
