A fan control system and a method thereof are provided. The fan control system is suited for a plurality of racks placed in an accommodation space. The fan control system includes a plurality of fan units and a fan control device. Each of the fan units is respectively disposed on each of the racks, and the fan units are arranged according to at least one air flow direction. The fan control device drives the fan units according to a driving sequence. In other words, the fan control device circularly and sequentially drives the fan units according to an order of the fan units. Thus, the fan control system maintains movement of air flow without driving all the fan units at the same time, so that the racks placed in the accommodation space are cooled efficiently and the required electric power is reduced.
