Forced air flow may be required to keep temperatures at or below the specified case temperatures of Table 3,
Column 2, in which case the drive should be oriented, or air flow directed, so that the least amount of air flow
resistance is created while providing air flow to the electronics and HDA. Also, the shortest possible path
between the air inlet and exit should be chosen to minimize the travel length of air heated by the drive and
other heat sources within the rack, cabinet, or drawer environment.
If forced air is determined to be necessary, possible air-flow patterns are shown in Figure 8. The air-flow patterns
are created by one or more 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.
