CPU_FAN1, PUMP_FAN1, SYS_FAN1~6: 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.
The auto mode fan connectors can automatically detect PWM and DC mode.
You can control fans in BIOS> HARDWARE MONITOR panel. It allows you to set DC
or PWM to your fan type. Check the Smart Fan Mode, the fan speed will change
according to the CPU or system temperature. Uncheck the Smart Fan Mode, the fan
will spin at maximum speed.
⚠
Important
Make sure fans are working properly after switching the PWM/ DC mode.
