Overview of Components
CPUFAN1~2, SYSFAN1~3: 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.
