voltage regulator placed parallel to the processor with the
airflow aligned with the devices. With this alignment, the heat
generated by the voltage regulator has minimal effect on the
processor.

A heatsink and fan combination can deliver much better
thermal performance than a heatsink alone. More importantly,
with a fan/sink the airflow requirements in a system design are
not as critical. A unidirectional heatsink with a fan moves air
from the top of the heatsink to the side. In this case, the best
location for the voltage regulator is on the side of the processor
in the path of the airflow exiting the fan sink (see Figure 118 on
page 321). This location guarantees that the heatsinks on both
