ABSTRACT

Systems and methods for smart power and fan speed control are described. In an
illustrative, non-limiting embodiment, an Information Handling System (IHS)
may include: a processor; and an embedded controller (EC) coupled to the
processor, where the EC is configured to control an operating aspect of a
cooling fan based upon a heat rejection or dissipation of a heatsink coupled
to the processor. In some other embodiments, a method can include calculating
a heat rejection or dissipation of a heatsink coupled to a heat producing
component of an IHS by determining a difference between a heatsink temperature
and an ambient temperature, and: (i) dividing the difference by a thermal
resistance of the heatsink, or (ii) multiplying the difference by a thermal
conductance of the heatsink; and adjusting a rotation speed of a fan
configured to cool the heat producing component based upon the calculation.
