A multi-pressure-quantity fan control system for a computer system is provided. The multi-pressure-quantity fan control system includes a controller. The controller provides a pressure-quantity control signal to a fan of the computer system, in order to set the fan to operate in one of a first pressure-quantity setting and a second pressure-quantity setting, wherein under a predetermined rotating speed, the fan has a first pressure-quantity curve for the first pressure-quantity setting and a second pressure-quantity curve for the second pressure-quantity setting.

A fan control system for a computer system is provided. The fan control system includes a power sensor and a controller. The power sensor detects the power dissipated by a target device in the computer system. The controller calculates a suggested airflow speed required for the target device and thus outputs a control signal for controlling a fan within the computer system according to at least the dissipated power.
