Winbond W83781D Setup Guide
The w83781D supports 3 Temperature Resister Sensors , voltage detection,
and fan speed sensor control.
1. 3 Temperature Resister Sensors:
a. RT2: This function is the CPU's temperature sensor.
b. RT1/RT3: These functions are the temperature sensor for the surrounded
PC environment.
c. You can connect the temperature resister wire to the RT2 socket in order
to sensor the CPU' s temperature, when you have placed the
temperature resister wire , tape the wire on top of the CPU heat sink.
d. You can connect the temperature resister wire to the RT1 socket in order
to control the system fan (JP9),when over temperature 60 degree
(default),the fan will turn on.
e. If you put the resister on top of RT1,RT2,RT3, you will be able to read
the temperature on W83781D AP.
2. Fan speed sensor control:
a. JP2 is the CPU' s Fan speed sensor control.
b. JP9 is the system Fan.
c. JP2 and JP9 is an optional function.
3. Voltage detection:
You can see the Voltage detection on W83781D AP.
