摘要： A notebook computer (1000) includes a base (100), a cover (300), a computer printed circuit board (PCB) (200) and a centrifugal fan (40). The cover covers the base, and cooperates with the base to form a receiving space (500) therebetween. The computer PCB is received in the receiving space and mounted on the base. The centrifugal fan is received in the receiving space, and includes a stator (401) and an impeller (402), rotatable with respect to the stator. The stator includes a motor (415) and a fan PCB (405) directly attached to the base. The motor electrically connects to the fan PCB. When the impeller rotates, airflow enters the receiving space through top and bottom air inlets (304, 104). The fan PCB is integrally formed with the computer PCB and has a height less than the computer PCB.
