Reference Voltage for temperature measuration.
Temperature sensor 3 input. It is used for temperature measu-
ration.
Temperature sensor 2 input. It is used for CPU1 temperature
measuration.
Temperature sensor 1 input. It is used for system temperature
measuration.
Over temperature Shutdown Output. It indicated the VTIN2 or
VTIN3 is over temperature limit.
Voltage Supply readouts from Pentium II.
0V to +5V amplitude fan tachometer input.
Alternate Function： Fan on-off control output.
These multifunctional pins can be programmable input or out-
put.
Fan speed control. Use the Pulse Width Modulatuion （PWM）
technic knowledge to control the Fan's RPM.
Beep function for hardware monitor. This pin is low after sys-
tem reset.
