Recommended Implementation
Configuring the ADT7467 as shown in Figure 54 provides the
system designer with the following features:
•
•
•
•
Two PWM outputs for control of up to three fans. (The
front and rear chassis fans are connected in parallel.)
Three TACH fan speed measurement inputs.
V
CPU core voltage measurement (V

The bidirectional THERM pin allows monitoring
PROCHOT output from, for example, an Intel Pentium 4
processor, or it can be used as an overtemperature THERM
output.
