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.
