This option is used to enable or disable smart fan function. 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.
Start 1 Temp(oC)
It allows you set a temperature value from which smart fan starts its operation.
Start 1 PWM Value
It allows you to set an initial PWM value to drive the fan when the temperature reaches Start
1 value and smart fan begins its operation. The higher PWM value can achieve the faster fan
speed.
Slope 1 Integer fraction
It is used to set the integer fraction of the slope 1 in PWM/Temperature diagram. The slope 1
controls the PWM value being stepped up or down versus temperature changes.
Slope 1 Decimal fraction
It is used to set the decimal fraction of slope 1 of smart fan curve.
Delta 1 Temp((oC)
It is used to set the delta value for temperature. When change of the temperature reaches
plus/minus delta 1 value, then the PWM will be increased or decreased by a step value based
on the slope 1 formula.
Start 2 Temp((oC)
Slope 2 Integer fraction
Slope 2 Decimal fraction
Delta 2 Temp((oC)
The definition of the above items are the same as slope 1 curve. The only difference is the
formula of slope 2 is defined as below :
For example, slope 1= 2.500, slope 2 integer fraction = 1, slope 2 decimal fraction = 0.125,
slope 2 = 2.500+1+0.125 = 3.625.
During the operation, the PWM value is subject to change based on the variation of
temperature. When temperature changes its value between start 1 temperature and full
limit, each time the change of temperature exceeding the delta value, the PWM will change
accordingly. If the temperature increases XoC, the PWM value will increase X*slope.
