A thermal module includes a fixing rack and a heat sink fitted in the fixing rack. The fixing rack is provided at an inner side with at least one stopper and at least one projected portion adjacent to and vertically lower than the stopper by distance. The heat sink is provided along an outer periphery at a predetermined position with at least one vertically extended groove. By vertically turning the heat sink by 180 degrees, the heat sink may be selectively fitted in the fixing rack with an upward-facing side thereof upward abutted on the upper stopper or the lower projected portion to restrict the fixing rack from sliding downward. Meanwhile, due to the height difference between the stopper and the projected portion, a distance between the upward-facing side of the heat sink and the fixing rack is adjustable.
