22 Elite 9 Product Manual, Rev. C
To confirm that required cooling for the Elite electronics and HDA is provided,
place the drive in its final mechanical configuration, perform random write/
read operations; and after the temperatures stabilize, measure the case
temperature of the components listed below.
Maximum allowable operating temperatures are listed in the last column.
Operation above these values may adversely affect the drive’s ability to
meet functional specifications.

The air-flow pattern with which the temperature guidelines above were
generated is shown in Figure 6. Local average air velocity was 200 lfpm and
inlet air temperature to the drive was 30°C (86°F).
The maximum allowable HDA case temperature is 55°C.
