1. A fan control system, which is used for dissipating heat from a computer device, the fan control system comprising:
a control interface, wherein the control interface is operated in an operating system of the computer device, and is able to obtain operation information of the operating system; and
a plurality of fan modules, wherein each one of the fan modules includes:
a controller connected to the control interface;
a fan electrically connected to the controller; and
one or more sensors electrically connected to the controller, wherein the sensor is used to detect an environment state of an environment in which the fan is located, so as to generate environment data; wherein one piece of the environment data indicates a temperature of the environment;
wherein the controller correspondingly controls a rotational speed of the fan according to the environment data transmitted by the connected sensor;
wherein the controller transmits real-time fan information to the control interface, and the real-time fan information includes the environment data, identification data, wind direction data, and rotational speed data; wherein the wind direction data is used to indicate whether the fan draws external air into the computer device or discharges air out of the computer device;
wherein the control interface receives the real-time fan information transmitted by the fan modules, and the control interface controls at least one of the fans to change a current rotational speed according to the operation information and the real-time fan information transmitted by the fan modules;
wherein the operation information includes a name of an application currently executed by the operating system, a used memory capacity, a used resource amount of a central processing unit, and a startup time, an operation duration, and a core temperature of the central processing unit of the computer device.
