1. An information handling system comprising:
a storage configured to store a thermal table associated with the information handling system;
a processor to communicate with the storage, the processor to:
detect that the information handling system is connected to a dock;
in response to the information handling system being connected to the dock, provide a dock temperature request to the dock;
receive a first temperature value for the dock when the dock includes at least one thermal sensor, wherein communication between the information handling system and the dock is a closed loop communication;
receive a second temperature value for the information handling system;
determine whether an acoustic level is met when thermal specifications are met based on the second temperature value;
retrieve thermal table data from the thermal table;
in response to the acoustic level not being met:
when the first temperature value is received, generate first and second fan control signals based on the first and second temperature values and the thermal table data; and
when the first temperature value is not received, generate the first and second fan control signals based on the second temperature value and the thermal table data; and
provide the first fan control signal to the dock, wherein based on the first fan control signal, the processor remotely controls an amount of cooling provided to the information handling system by a first airflow of a first cooling fan in the dock; and
a second cooling fan to provide a second airflow based on the second fan control signal, wherein the first and second airflows are provided to the information handling system without the acoustic level being exceeded.
