Overview of Components

CPUFAN1,SYSFAN1~2: Fan Connectors

Fan connectors can be classified as PWM (Pulse Width Modulation) Mode and

Voltage Mode. PWM Mode fan connectors provide constant 12V output and adjust fan

speed with speed control signal. Voltage Mode fan connectors control fan speed by

changing voltage. Therefore, when you plug a 3-pin (Non-PWM) fan to a PWM Mode

fan connector, the fan speed will be always maintained at 100%, and that could be

noisy.

Controlling the fan speed

There are two ways to manage fan speed. One is to go to BIOS > HARDWARE

MONITOR. The other is to use COMMAND CENTER application.

BIOS > HARDWARE MONITOR COMMAND CENTER

Both methods offer gradient points of the fan speed that allow you to adjust fan speed

in relation to CPU temperature.
