CPU_FAN1, SYS_FAN1: 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. When you plug a 3-pin (Non-PWM) fan to a fan connector in PWM mode, the
fan speed will always maintain at 100%, which might create a lot of noise. You can
follow the instruction below to adjust the fan connector to PWM or DC Mode.
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.
