Excess heat may cause deterioration in the operational stability of the electronic components and may damage the electronic components. Thus, excess heat must be removed quickly to maintain an acceptable operating temperature of the electronic components in the computer. One method for removing heat from an electronic component is by mounting a heat dissipating apparatus on the electronic component. However, the dissipating apparatus of related art may be inadequate to satisfy the ever-increasing demand for heat dissipation.
- Therefore, there is room for improvement within 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 embodiments.
