Bit 5: Set 1, SYSFANOUT voltage will decrease to and keep the value set in Index 08h when
temperature goes below target range. This is to maintain the fan speed in a minimum value.
Set 0, SYSFANOUT duty cycle will decrease to 0 when temperature goes below target range.
Bit 4: Set 1, CPUFANOUT duty cycle will decrease to and keep the value set in Index 09h when
temperature goes below target range. This is to maintain the fan speed in a minimum value.
Set 0, CPUFANOUT duty cycle will decrease to 0 when temperature goes below target range.
Bit 3: Set 1, AUXFANOUT duty cycle will decrease to and keep the value set in Index 15h when
temperature goes below target range. This is to maintain the fan speed in a minimum value.
Set 0, AUXFANOUT duty cycle will decrease to 0 when temperature goes below target range.
Bit2-1: AUXFANOUT mode control.
Set 00, AUXFANOUT is as Manual Mode. (Default).
Set 01, AUXFANOUT is as Thermal Cruise Mode.
Set 10, AUXFANOUT is as Fan Speed Cruise Mode.
Set 11, reserved and no function.
