1. A method comprising:
- configuring a computer system with an operating system, a fan in communication with a target device, and a controller connected to the fan;
connecting a detecting circuit to the target device, the circuit detecting a time-variable rate of current consumed by the target device and sending an indicative signal to the controller in response to detection of the time variable rate of current;
managing a rotational speed of the fan with the controller, including adjusting the rotational speed of the fan according to the time-variable rate of current in response to a surge of workload, wherein the adjusting is instantaneous;
controllably driving the fan to operate at a maximum rotation speed through the controller when the operation state is a first predetermined state and the time-variable rate of current exceeds a first predetermined value, wherein the first predetermined state comprises a first power state (PS) mode at least partially defined with a first current consumed by the target device and at least one second PS mode at least partially defined with at least one second current consumed by the target device, wherein the first current is greater than the second current; and
executing a predetermined operation through the operating system when the operation state is a second predetermined state and the time-variable rate of current exceeds a second predetermined value.

Abstract
A fan control system includes a fan and a target device. The fan control system includes a controller to control the rotation speed of the fan. The controller controls the rotation speed according to a time-variable rate of current consumed by the target device. Particularly, when the time-variable rate of current exceeds a threshold, the controller controls the fan to operate at a maximum rotation speed.
