Provided is a cooling fan including: a fan housing having an air inlet formed on a front surface thereof and through which air flows and an air outlet formed at a side surface of the fan housing and through which air is discharged; and an impeller mounted inside the fan housing to introduce air in an axial direction thereof and discharge air in a radial direction thereof, wherein a bypass passage is formed at an edge of the air inlet so that air flowing in a direction opposite to the air outlet can be discharged to the outside. At high power of a cooling fan, backward-flow air is discharged to the outside to minimize noise and improve blowing efficiency.
