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
