Abstract
The present disclosure provides a motherboard protection circuit and a server. The motherboard protection circuit includes a baseboard management controller (BMC), a first connector and a first conversion circuit. The first connector outputs a first rotational speed signal when a fan is electrically connected to the first connector. The first conversion circuit is electrically connected between the BMC and the first connector, the first conversion circuit converts a first voltage of the first rotational speed signal into a second voltage and output a converted first rotational speed signal to the BMC. The BMC monitors a rotational speed of the fan according to the converted first rotational speed signal. The first conversion circuit maintains the voltage of the rotational speed signal to an ideal voltage, and outputs the rotational speed signal to the BMC, so that the BMC can normally receive the rotational speed signal.
