Fan module
A fan module comprises a frame, a wire-stopping structure, an impeller and a circuit board. The frame includes a frame wall, a base, a plurality of static blades and a connector. A wire groove formed on an outside of the frame wall to accommodate a wire. The static blades are radially connected to the base and the frame wall. The connector is formed on the outside of the frame wall and extended from one end of the wire groove to the base along one of the static blades. The connector includes a plurality of pins. The wire-stopping board is fixed to the frame wall to cover the wire groove. The impeller is disposed in the frame. The circuit board is disposed in the frame and located on the base. The circuit board includes a plurality of pin holes, and the pin holes are electrically connected to the pins.
1. A fan module, comprising:
a frame, includes:
