1. An information handling system, comprising:
a processor; and
an embedded controller coupled to the processor;
wherein the processor is configured to:
determine that an inventory of components of the information handling system includes at least a first fan and an information handling system card;
determine whether a headphone plug has been inserted into a headphone jack of the information handling system;
determine that the information handling system card includes at least a second fan; and
receive first user input indicating a first maximum acoustic sound pressure level associated with operating the information handling system; and
in response to the processor determining that the headphone plug is not inserted into the headphone jack:
the embedded controller is configured to:
determine a first maximum power consumption for the information handling system card based at least on the first maximum acoustic sound pressure level, a current acoustic sound pressure level associated with the second fan of the information handling system card, and a current acoustic sound pressure level associated with the first fan of the information handling system at a sensor spaced-apart from the information handling system card;
determine a first maximum fan speed for the at least the first fan based at least on the first maximum acoustic sound pressure level;
determine a second maximum fan speed for the at least the second fan based at least on the first maximum acoustic sound pressure level;
provide first configuration information, which indicates the first maximum fan speed for the at least the first fan, to a fan controller of the information handling system that controls the at least the first fan; and
provide second configuration information, which indicates the first maximum power consumption and the second maximum fan speed for the at least the second fan, to the information handling system card;
the fan controller configured to control a fan speed of the first fan based on the first configuration information;
the information handling system card configured to control a fan speed of the second fan based on the second configuration information;
in response to the processor determining that the headphone plug is inserted into the headphone jack:
the embedded controller is configured to:
determine a second maximum acoustic sound pressure level associated with operating the information handling system, wherein the second maximum acoustic sound pressure level is greater than the first maximum acoustic sound pressure level;
determine a second maximum power consumption for the information handling system card based at least on the second maximum acoustic sound pressure level, the current acoustic sound pressure level associated with the second fan of the information handling system card, and the current acoustic sound pressure level associated with the first fan of the information handling system at the sensor spaced-apart from the information handling system card;
determine a third maximum fan speed for the at least the first fan based at least on the second maximum acoustic sound pressure level;
determine a fourth maximum fan speed for the at least the second fan based at least on the second maximum acoustic sound pressure level;
provide third configuration information, which indicates the third maximum fan speed for the at least the first fan, to the fan controller of the information handling system;
provide fourth configuration information, which indicates the second maximum power consumption and the fourth maximum fan speed for the at least the second fan, to the information handling system card;
the fan controller configured to control the fan speed of the first fan based on the third configuration information; and
the information handling system card configured to control the fan speed of the second fan based on the fourth configuration information.
