8.3 Cooling
The host enclosure must provide heat removal from the drive. You should confirm that the host enclosure is
designed to ensure that the drive operates within the temperature measurement guidelines described in Sec-
tion 6.4.1. In some cases, forced airflow may be required to keep temperatures at or below the temperatures
specified in Section 6.4.1.
If forced air is necessary, possible air-flow patterns are shown in Figure 7. The air-flow patterns are created by
fans either forcing or drawing air as shown in the illustrations. Conduction, convection, or other forced air-flow
patterns are acceptable as long as the temperature measurement guidelines of Section 6.4.1 are met.
