Abstract: A fan control system includes a fan, a first temperature sensor, a calculating unit, a logic controller, and a memory unit. The first temperature sensor continuously senses temperatures of a device during a time period, in order to obtain a plurality of sampled temperatures. The calculating unit selects N1 latest sampled temperatures and N2 latest sampled temperatures from the sampled temperatures, and calculates a first average temperature according to the N1 sampled temperatures and a second average temperature according to the N2 sampled temperatures. N1 and N2 are positive integers. The logic controller is configured to select one of the first average temperature and the second average temperature to output as a compensation temperature. The memory unit is configured to store an operating table, and configured to output a rotational speed control signal to the fan corresponding to the operating table according to the compensation temperature.

Abstract: A centrifugal fan comprises a casing and a fan impeller. The casing comprises a first cover, a second cover, a side wall structure and a isolating structure. The side wall structure is connected between the first cover and the second cover to form an accommodating space. The side wall structure includes a first air inlet and an air outlet. The isolating structure is disposed between the first cover and the second cover to distinguish the accommodating space into a first subspace and a second subspace. The isolating structure includes a through hole. As a result, airflow is guided from a side to the first air inlet easily. Then, the air inlet volume and air outlet volume of the centrifugal fan are improved.
