Abstract

The present invention provides a dual-fan abnormal control device for computer host and comprises a first coil, a second coil, a first driving integrated circuit (IC), a second IC, a controller, and a voltage level comparison circuit. The voltage level comparison circuit performs voltage division on the first and second reference potential signals inputted by the first and second driving ICs to obtain a third reference potential signal. By comparing the potential of the third reference potential signal and that of the basic pulse signal outputted from the output end of the first driving IC, either a high level pulse voltage signal or a low voltage flat signal can be determined to be outputted to the controller for processing. The controller outputs a control gate on or off signal to the first and second driving ICs to control the operations of the first and second coils.
