CPU_FAN1, PUMP_FAN1, SYS_FAN1~7: 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.
This motherboard can automatically detect PWM and DC mode. However, you can
follow the instruction below to adjust the fan connector to PWM or DC Mode manually.
Switching fan mode and adjusting fan speed
