Diymore 5/12V 4-Wire PWM Fan Temperature Controller — Smart Fan Temperature Controller with Multiple Operating Modes

Features1. Compatible with 5V/12V four-wire fans; works in a variety of scenarios2. Automatically adjusts speed based on temperature; operates quietly at low speeds and provides maximum cooling at full speed3. Users can customize the activation temperature, activation duty cycle, and temperature difference for full-speed operation4. 343 combination modes to accommodate a wide range of scenarios5. Precise four-wire PWM speed control for quiet and efficient operationParameterProduct Name: Fan Temperature ControllerSupported Fans: 5V/12V standard 4-wire PWM fans (does not support 2- or 3-wire fans)Input Voltage: 5–15V (input and output are connected in series; note the fan’s voltage rating)Fan Current: Less than 2A (For high current, 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 difference1. Activation temperature: {35, 40, 45, 50, 55, 60, 65} // Default 45°C2. Start Ratio: {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 stops when the temperature drops to 3°C below the start temperatureExample: With a start temperature of 45°C, a start percentage of 25%, and a full-speed temperature difference of 20°C, the fan starts at 25% when the temperature rises to 45°C, runs at full speed once it reaches 65°C (45 + 20), and stops when the temperature drops to 42°C.Package includeTemperature-controlled speed regulator *110 cm epoxy resin probe *1
