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.
You can control fans in BIOS> HARDWARE MONITOR panel. It allows you to set DC or
PWM to your fan type.
⚠
Important
Make sure fans are working properly after switching the PWM/ DC mode.
