 Fan 3 PWM Control [070]
The Fan 3 PWM Control option can only be set if the CPU FAN Mode Setting option is
set to Manual Mode. Use the Fan 3 PWM Control option to select PWM duty cycle
control. The PWM duty cycle specifies the width of the modulated pulse. A high value
ensures a wide pulse and a low value ensures a narrow pulse. To select a value, select
the Fan 3 PWM Control option and enter a decimal number between 000 and 127. The
PWM Duty Cycle control range is specified below.
 PWM Minimum Mode: 0
 PWM Maximum Mode: 127
