The air-flow pattern with which the temperature guidelines above were
generated is shown in Figure 6. Local average air velocities were 0.61 msec
(120 lfpm) and inlet air temperature to the drive was 30°C (86°F), plus a 5°C
temperature rise in the test enclosure (35°C ambient local to the drive).
The maximum allowable HDA case temperature is 60°C.
