• Monitors the operating status of the fans and indicates the current status of the fan box through the LEDs
• Reports the operating status of the fan box and receives the instructions on adjusting the fan speed
• Adjusts the fan speed intelligently according to the temperature data collected by the temperature sensor
• Provides Pulse-Width Modulation (PWM) control signals for fan speed adjustment
• Reports the operating status and alarms of the fan box through the LEDs
