 '''*Note: This feature is only on certain baseboards. Please consult the hardware manual.'''
 
-A pulse width modulated (PWM) fan controller is supported by some boards. The GSC controller allows the fan speed to be varied based upon temperature to help reduce bearing wear and extend fan lifetime. The fan controller contains six temperature set points which correspond to duty cycles ranging from 50 to 100 percent (fully on). See the below chart for the PWM duty cycle versus temperature set points.

-'''*Note: typically the PWM occurs on the ground pin, and the 5V is constant. However, consult the hardware manual to determine if your board uses that configuration.'''

The GSC controller allows the fan speed to be varied based upon temperature to help reduce bearing wear and extend fan lifetime. The fan controller contains six temperature set points which correspond to duty cycles ranging from 50 (half on, half off) to 100 percent (fully on). See the below chart for the PWM duty cycle versus temperature set points.
