This option is used to enable or disable smart fan function. Default value is [Disabled]. Only
when this option is enabled, you can set some correlative parameters. "Smart Fan Automatic
Mode" is the principle figure of CPU smart fan function for your reference.
► CPU Fan Stop Temperature
It allows you set a temperature value. When CPU temperaure is lower than this value or is
at this value, CPU smart fan will stop its operation.
► CPU Fan Start Temperature
It allows you set a temperature value from which CPU smart fan starts its operation.
► CPU Fan Start PWM Value
It allows you to set an initial PWM value to drive the CPU fan when CPU temperature reaches
Start value and CPU fan begins its operation. The higher PWM value can achieve the faster
fan speed.
► CPU Fan Slope PWM Value
It is used to set the slope value in PWM/Temperature diagram. The slope value controls the
PWM value being stepped up or down versus temperature changes.
► CPU Fan Delta Temperature
It is used to set the delta value for temperature. When the change of temperature reaches
plus/minus delta value, the PWM will be increased or decreased by a step value based on the
slope formula.
► System Fan Stop Temperature
It allows you set a temperature value. When system temperaure is lower than this value or is
at this value, system fan will stop its operation.
► System Fan Start Temperature
It allows you set a temperature value from which system fan starts its operation.
► System Fan Start PWM Value
It allows you to set an initial PWM value to drive the system fan when system temperature
reaches Start value and system fan begins its operation. The higher PWM value can achieve
the faster fan speed.
► System Fan Slope PWM Value
It is used to set the slope value in PWM/Temperature diagram. The slope value controls the
PWM value being stepped up or down versus temperature changes.
