10. A method, comprising:
setting, by a mode controller of an information handling system, a cooling fan to be operated in a first one of a plurality of fan speed levels:
setting a processor of the information handling system to a first one of a plurality of performance levels;
receiving a first indication that a headphone device is connected to a connector of the information handling system; and
in response to receiving the first indication, determining that the information handling system is in a first operating mode, wherein the first operating mode is associated with a quiet operation of the information handling system, and in response to determining that the information handling system is in the first operating mode:
maintaining the cooling fan in the first fan speed level;
maintaining the processor in the first performance level; and
detecting that the information handling system has changed to a second operating mode, wherein the second operating mode is associated with a high performance operation of the information handling system; and
in response to detecting that the information handling system is in the second operating mode:
determining whether or not a thermal sensor reading of the information handling system is high;
setting the cooling fan in a second one of the plurality of fan speed levels, the second fan speed level being a higher fan speed level than the first fan speed level in response to determining that the thermal sensor reading is not high; and
setting the processor in a second one of the plurality of performance levels, the second performance level being a higher performance level than the first performance level in further response to determining that the thermal sensor reading is not high.
11. The method of claim 10 , further comprising:
receiving a second indication that the headphone device is no longer connected to the connector; and
setting the cooling fan in the first fan speed level in response to receiving the second indication.
12. The method of claim 10 , further comprising:
receiving a second indication that audio information is being provided to the headphone device, wherein setting the cooling fan to the second fan speed is in further response to receiving the second indication.
13. The method of claim 12 , further comprising:
receiving a third indication that the audio information is no longer being provided to the headphone device; and
setting the cooling fan in the first fan speed levels in response to receiving the third indication.
14. The method of claim 12 , further comprising:
receiving a third indication that the audio information is not being muted, wherein setting the cooling fan to the second fan speed is in further response to receiving the third indication.
