CPU_FAN1, PUMP_FAN1, SYS_FAN1~4: Fan Connectors
Fan connectors can be classified as PWM (Pulse Width Modulation) Mode or DC Mode.
PWM Mode fan connectors provide constant 12V output and adjust fan speed with
speed control signal. DC Mode fan connectors control fan speed by changing voltage.
You can follow the instruction below to adjust the fan connector to PWM or DC Mode.
CPU_FAN1 is the auto-detection mode fan connector, the system will auto detect the
fan mode.
