► Delta Temperture
It is used to set the delta value for temperature. When change of the temperature reaches
plus/minus delta value, then the PWM will be increased or decreased by a step value based
on the slope formula.
► System Smart fan Control
This option is used to enable or disable system smart fan function. Only when this option is
enabled, you can set some correlative parameters.
► PWM Start Temperature
It allows you set a temperature value from which smart fan starts its operation.
► Start PWM Value
It allows you to set an initial PWM value to drive the fan when the temperature reaches Start
value and smart fan begins its operation. The higher PWM value can achieve the faster fan
speed.
► Slope PWM Value
It controls the PWM value being stepped up or down versus temperature changes.
► Delta Temperture
It is used to set the delta value for temperature. When change of the temperature reaches
plus/minus delta value, then the PWM will be increased or decreased by a step value based
on the slope formula.
