A cooling fan device for mounting on top of parallel radiation fins of a radiator. The device includes a seat having a driving section, and an air-guiding fan pivotally connected to the driving section of the seat and including a hub and blades generally radially spaced around an outer periphery of the hub. Supporting sections are extended from two opposite sides of the driving section in directions parallel with the radiation fins of the radiator to support the driving section in the seat. With the supporting section in parallel with the radiation fins, flowing air produced by the air-guiding fan is allowed to flow toward the radiator without hindrance.
