8. An IHS (Information Handling System) comprising:
a first processor;
a plurality of cooling fans;
an airflow controller comprising a memory device having instructions stored thereon that, upon execution by a logic unit, cause the airflow controller to:
measure a turbo frequency supported by the first processor at each of a series of temperature margins that are progressively lower than a specification temperature of the first processor;
determine a rate of increase in the measured turbo frequencies at each of the temperature margins of the series;
identify a first temperature margin of the series at which the rate of increase in the supported turbo frequencies falls below a first threshold; and
utilize the first temperature margin in providing airflow cooling to the first processor using the plurality of cooling fans.
