POWER
+3.3V pin. Can be powered by +3.3V Standby power if
monitoring in low power states is required. This pin should
be bypassed with a 0.1

Remote Thermal Diode
Positive Input
Positive input (current source) from the remote thermal
diode serves as the positive input into the A/D. Connected
to the anode of a CPU thermal diode or the base-collector of
a diode connected MMBT3904 NPN transistor.
Negative input (current sink) from the remote thermal diode
serves as the negative input into the A/D. Connected to
cathode of a CPU thermal diode or the emitter of a diode
connected MMBT3904 NPN transistor.
Input for monitoring tachometer output of fan (default) or
ALERT
output selectable by configuration register 09h, bit 5.
