Switching fan mode and adjusting fan speed
You can switch between PWM mode and DC mode and adjust fan speed in BIOS >
HARDWARE MONITOR.
Select PWM mode or DC mode
⚠
Important
Make sure fans are working properly after switching the PWM/ DC mode.
There are gradient points of the fan speed that allow you to adjust
fan speed in relation to CPU temperature.

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.
