1. Technical Field
This disclosure relates to fan fastening devices, particularly to a fan fastening device for a server.
2. Description of Related Art
A typical fan module of a server generally includes a fastening housing and a plurality of fans fixed on the fastening hosing. However, in the conventional product configurations, the fan module is typically fixed to the server by some screws. Thus, it is difficult to fix or detach the fan module to or from the server without a tool, such as a screwdriver.
Therefore, there is a room for improved in the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the exemplary fan fastening device. Moreover, in the drawings like reference numerals designate their respective parts throughout the several views. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment.
