1. A method for maintaining a threshold operating temperature in an information handling system, the method comprising:
identifying, by an embedded controller (EC) of the information handling system, an operating temperature associated with the information handling system;
determining, by the EC, a first fan speed associated with one or more fans of the information handling system based on the operating temperature;
causing, by the EC, the one or more fans to rotate based on the first fan speed;
identifying, by the EC, that the operating temperature has increased to reach the threshold operating temperature; and
in response to identifying that the operating temperature has increased to reach the threshold operating temperature:
determining, by the EC, a relationship model between power consumption level of the information handling system and fan speed of the one or more fans to maintain the information handling system operating at the threshold operating temperature;
identifying, by the EC, a current power consumption level associated with the information handling system;
determining, by the EC and as indicated by the relationship model, a second fan speed associated with the one or more fans corresponding to the current power consumption level; and
causing, by the EC, the one or more fans to rotate based on the second fan speed to maintain the information handling system operating at the threshold operating temperature.
