Type
Power GROUND is the power supply ground
Power Fan Power +12VDC
Sense FAN_TACH signal is connected to the SMsC* SCH5027 or SCH5017 to
monitor the fan speed.
Control Pulse Width Modulation – Fan speed Control signal
Power GROUND is the power supply ground
Power Fan Power +12VDC
Sense FAN_TACH signal is connected to the SMsC* SCH5027 or SCH5017 to
monitor the fan speed. It use a different TACH input other than TACH1.
Control Pulse Width Modulation – Fan speed Control signal . It used the same
PWM signal as PWM1
