B75H2-M3 USER MANUAL

Smart Fan Mode (Normal)

This item allows you to select the fan mode (Normal, Quiet, Silent, or Manual) for a

better operation environment. If you choose Normal mode, the fan speed will be

auto adjusted depending on the CPU temperature. If you choose Quite mode, the

fan speed will be auto minimized for quiet environment. If you choose Silent mode,

the fan speed will be auto restricted to make system more quietly. If you choose

Manual mode, the fan speed will be adjust depending on users’ parameters.

Smart Fan start PWM value (180/80)

Smart Fan start PWM TEMP(-) (30)

This item is used to set the start PWM value of the smart fan.

This item is used to set the start temperature of the smart fan.

DeltaT (+3)

This item specifies the range that controls CPU temperature and keeps it from going

so high or so low when smart fan works.

Smart Fan Slope PWM value (10 PWM value/unite)

This item is used to set the Slope Select PWM of the smart fan.

This item is used to set the CPU/System/Power fan full speed offset value.

CPU/System/Power Smart Fan Control (Enabled)

This item enables you to define the CPU/System/Power by smartly adjusting the

CPU/System/Power Fan. When it is set at certain temperature, the CPU/System/

Power Fan PWM value will change accordingly.
