Airflow requirements

The enclosure design must ensure adequate cooling for the drive. Note that the

fan in the power supply cools only the power supply’s internal parts.

The drive’s product specification (document 64403601) describes how to

evaluate the airflow design. The evaluation consists of ensuring that the case

temperatures of certain critical components remain within acceptable limits

during drive operation.

We recommend orienting the drive or directing the airflow in a way that creates

the least amount of airflow resistance while providing airflow above the circuit

boards and around the head and disc assembly (HDA). Also, choose the

shortest possible path between the air inlet and exit. This minimizes the

distance traveled by air that is heated by the drive and by other nearby heat

sources.

Figure 3 shows two design approaches with one or more fans used to

generate air flow. The airflow patterns can be created by the fans either pushing

or drawing air. The overall flow pattern can be directed from front to back, back

to front, or side to side.
