1. An apparatus having an active cooling system, comprising:

  • electronic circuits;

    an enclosure for housing the electronic circuits;

    a fan for blowing air through the enclosure;

    an orientation sensor for sensing a parameter indicative of an orientation of the fan; and

    logic configured to determine, based on the parameter sensed by the orientation sensor, whether a direction of an airflow induced by the fan is within a predefined range of a direction of buoyant airflow, the logic further configured to transmit a notification signal indicating whether the direction of the airflow induced by the fan is within the predefined range.
