outputs. Automatic fan control, then, ultimately allows
graceful fan speed changes that are less perceptible to the
system user.

Step 1: Hardware Configuration
During system design, the motherboard sensing and
control capabilities should be addressed early in the design
stages. Decisions about how these capabilities are used
should involve the system thermal/mechanical engineer.
Consider the following questions:
1. What ADT7473/ADT7473 ? 1 functionality will be
used?
? PWM2 or SMBALERT for ADT7473?
? THERM_LATCH or PWM2 for ADT7473 ? 1?
? TACH4 fan speed measurement or
over-temperature THERM function?
The ADT7473/ ADT7473 ? 1 offers multifunctional
pins that can be reconfigured to suit different
system requirements and physical layouts. These
multifunction pins are software programmable.
This influences the choice of whether t o use the
TACH4 pin or to reconfigure it for the THERM
function.
3. Is the CPU fan to be controlled using the
ADT7473/ADT7473 ? 1 or will it run at full speed
100% of the time?
If run at full speed, 100% of the time, this frees up
a PWM output, but the system is louder.
4. Where will the ADT7473/ADT7473 ? 1 be
physically located in the system?
This influences the assignment of the temperature
measurement channels to particular system
thermal zones. For example, locating the
ADT7473/ADT7473 ? 1 close to the VRM
controller circuitry allows the VRM temperature to
be monitored using the local temperature channel.
2. How many fans will be supported in the system,
three or four?
