Abstract: In IHSs (Information Handling Systems), cooling is provided by increasing the airflow generated by cooling fans. However, unnecessary airflow cooling results in noise and wasted energy. An IHS processor may support faster operating frequencies when cooled below an upper threshold, but these operating frequencies drop at temperatures below a lower threshold. Embodiments provide techniques for calibrating the cooling of an IHS to the thermal characteristics of a specific processor since manufacturing variances result in processors having differing responses to cooling. A turbo frequency supported by a processor is measured at a series of temperature margins that are progressively lower than the processor's specification temperature. A rate of increase in the measured turbo frequencies is determined at each of the temperature margins. A first temperature margin is identified at which the rate of increase in turbo frequencies falls below a threshold. This margin is used in providing airflow cooling.

The audio chamber volume may adjust based upon the information handling system housing rotational orientation, the type of audio played at the audible speaker, or other conditions.
