A fixing apparatus includes an elongated base and a fixing member fixed to a bottom of a fan. The base defines a number of pairs of latching holes spaced in a longitudinal direction of the base. Two pairs of latching feet protrude from a bottom surface of the fixing member to extend through two pairs of the latching holes and engage with a bottom of the base. A hook extends from the fixing member to engage with a side of the base. The fixing member can fix the fan to different places of the base.
