CPUFAN, SYSFAN1: 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 > Advanced >
Hardware Monitor. The other is to use COMMAND CENTER application.
COMMAND CENTER
BIOS Hardware Monitor sub-menu allows you to set the temperature levels and the
corresponding fan speed levels.
COMMAND CENTER offers gradient points of the fan speed that allow you to adjust
fan speed in relation to CPU temperature.
