Beschreibung
Zusammenfassung:	The invention provides a monitor circuit, which is used for a fan and receives a driving current and a driving voltage of the fan. The monitor circuit includes sensing circuits and a microcontroller. The sensing circuits respectively sense statuses of the fan and output sensing values. The microcontroller is used for monitoring whether the sensing values exceed preset value ranges respectively to obtain comparison results. The microcontroller outputs warning signals according to the comparison results. Each of the warning signals has a specific frequency.
