1. An information handling system comprising:
a chassis including a cold aisle edge and a hot aisle edge;
one or more devices inserted within the cold aisle edge;
a plurality of cooling fans located along the hot aisle edge, wherein the plurality of cooling fans have a first fixed airflow direction to pull a first airflow from the cold aisle edge across the one or more devices and out the hot aisle edge;
a power supply unit including a power supply cooling fan located within a housing of the power supply unit, the power supply unit to provide power to the one or more devices, the power supply cooling fan to provide a second airflow through the power supply unit and not across the one or more devices; and
a baseboard management controller to:
determine whether the power supply cooling fan of the power supply unit installed within the information handling system has a fixed airflow direction or changeable airflow direction;
in response to the power supply cooling fan having the fixed airflow direction, the baseboard management controller to:
determine a configuration of the information handling system, wherein the configuration of the information handling system includes a location of the power supply unit along the cold aisle edge or along the hot aisle edge;
determine a power supply cooling fan orientation of the power supply cooling fan within the power supply unit;
determine whether the power supply cooling fan orientation corresponds to the configuration of the information handling system, wherein the power supply cooling fan orientation corresponds to the configuration of the information handling system when the power supply cooling fan moves the second airflow within the power supply unit from the cold aisle edge to the hot aisle edge;
in response to the power supply cooling fan orientation corresponding to the configuration of the information handling system, provide the second airflow within the power supply unit; and
in response to the power supply cooling fan orientation not corresponding to the configuration of the information handling system, provide an alert message to an individual associated with the information handling system.
