Figure 4. Airflow Temperature Measurement Locations
Airflow velocity should be measured using industry standard air velocity sensors.
Typical airflow sensor technology may include hot wire anemometers.
Figure 4
provides guidance for airflow velocity measurement locations. These locations are for
a typical JEDEC test setup and may not be compatible with chassis layouts due to the
proximity of the processor to the (G)MCH. The user may have to adjust the locations
for a specific chassis. Be aware that sensors may need to be aligned perpendicular to
the airflow velocity vector or an inaccurate measurement may result. Measurements
should be taken with the chassis fully sealed in its operational configuration to achieve
a representative airflow profile within the chassis.
