Abstract
A method for controlling fan speed includes providing a fan that is in fluid communication with at least one heat producing component, detecting a temperature, determining a fan speed using the detected temperature and a nonlinear fan speed function, and applying a control signal to the fan such that the fan operates at the determined fan speed in order to cool the at least one heat producing component.
