Product Specifications Product Name: Fan Temperature Controller Supported 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=3950 PWM signal: 25 kHz, Vpp = 5 V

Temperature Control Strategy 343 combination modes Parameter settings: Activation temperature, activation ratio, full-speed temperature difference 1. Activation temperature: {35, 40, 45, 50, 55, 60, 65} // Default 45°C 2. Start Ratio: {20, 25, 30, 35, 40, 50, 60} // Default 25°C 3. Full-Speed Temperature Differential: {5, 10, 15, 20, 30, 40, 50} // Default 20°C Delayed Shutdown: Operation stops when the temperature drops to 3°C below the start temperature Example: 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.
