Product parameters
Product Name: Fan Temperature Controller
Support fan: 5V/12V standard four wire PWM fan (does not support 2/3 wires)
Input voltage: 5-15V (direct input/output, pay attention to fan withstand voltage)
Fan current: less than 2A (for high currents, it is recommended to connect the fan interface to the power supply)
Fan terminal: MX2.54 3+1P half backrest (B3 terminal)
Standby power consumption: 10mW (5V); 25mW（12V）
Temperature probe: NTC 50K B=3950
PWM signal: 25KHz Vpp=5V
Temperature control strategy
343 combination modes
Parameter settings: startup temperature, startup ratio, full speed temperature difference
1. Startup temperature: {35, 40, 45, 50, 55, 60, 65}//Default 45 ° C
2. Startup ratio: {20, 25, 30, 35, 40, 50, 60}//Default 25 ° C
3. Full speed temperature difference: {5, 10, 15, 20, 30, 40, 50}//Default 20 ° C
Delayed shutdown: Stop running when the temperature drops to 3 ° C below the starting temperature
For example, the starting temperature is 45 ° C, the starting ratio is 25%, and the temperature difference at full speed is 20 ° C. That is, when the temperature rises to 45 ° C, the fan starts at 25% and reaches 65 ° C (45+20) at full speed. When the temperature drops to 42 ° C, the fan stops.
