CONSTITUTION: A cooling fan is mounted at a VGA(Video Graphics Array) heatsink plate or a CPU(Central Processing Unit), and plural wings(110) are installed at the cooling fan. The plural wings are rotated by a central rotary motor(130), and a support frame(200) covers the upper and lateral portions of the wing. Plural insertion holes are formed in the length direction of the lower portion of the wing, and a brush is coupled to the first insertion hole.
