Bit 7: Reserved
Bit 6: Set 1, CPUFANOUT1 value will decrease to and keep the value set in Index 64h when
Bit 5: Set 1, SYSFANOUT value will decrease to and keep the value set in Index 08h when
Bit 4: Set 1, CPUFANOUT0 value will decrease to and keep the value set in Index 09h when
Bit 3: Set 1, AUXFANOUT value will decrease to and keep the value set in Index 17h when
Bit 2-1: AUXFANOUT mode control.
Bit 0: AUXFANOUT output mode selection. Set to 0, AUXFANOUT pin is as PWM output duty cycle
so that it can drive a logical high or low signal. Set to 1, AUXFANOUT pin is as DC voltage output
which can provide analog voltage output. (Default 0)
Set 0, SYSFANOUT value will decrease to 0 when temperature goes below target range.
Set 0, CPUFANOUT0 value will decrease to 0 when temperature goes below target range.
Set 0, AUXFANOUT value will decrease to 0 when temperature goes below target range.
temperature goes below target range. This is to maintain the fan speed in a minimum value.
Set 0, CPUFANOUT1 value will decrease to 0 when temperature goes below target range.
temperature goes below target range. This is to maintain the fan speed in a minimum value.
temperature goes below target range. This is to maintain the fan speed in a minimum value.
temperature goes below target range. This is to maintain the fan speed in a minimum value.
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.
