A fan connector comprises a connector body, a plurality of chip terminals, a plurality of wiring terminals, and a chip circuit board. The connector body comprises an electrical connection slot, a chip slot, and a wiring slot. The plurality of chip terminals and the plurality of wiring terminals are disposed on a sidewall of the electrical connection slot. The plurality of chip terminals corresponds to the plurality of wiring terminals, respectively. The chip circuit board comprises a chip, a circuit board, and a plurality of conductive pads. The chip circuit board is inserted into the chip slot. The plurality of conductive pads is in contact with the corresponding chip terminals. One end of the connector body is connected to a fan, in which a wire passes through the wiring slot and connects to the plurality of wiring terminals. An external plug is possible to insert into the electrical connection slot.
