The present invention is a printed circuit board having cooling means incorporated therein, which is coordinated with a fan. The fan comprises a frame, a stator, a rotator and a circuit board. The circuit board comprises at least one electronic component, a control IC and a heat discharge region. The heat discharge region comprises two heat dissipation areas with a plurality of holes; and the control IC is at a position corresponding to the heat discharge region. Accordingly, the circuit board can be ventilated and its heat-transfer structure can be destroyed to further obtain a better heat discharge so that the work efficiency of the control IC can be improved.
