Manufacturing processes continue to get better, allowing computer manufacturers to fit more circuits into a smaller chip. While this greatly enhances the speed and performance of advanced architecture processors, it also increases the heat generated. This can be compounded by the ability to overclock processors, increasing their power even more at the cost of additional heat. It is highly recommended to use additional cooling methods when overclocking your laptop.
Air Flow
One of the most efficient ways to cool a computer is through the introduction of airflow over the components. The majority of laptop components are located underneath the keyboard which means that internal fans are also located there. In order for fans to work correctly, they need access to good airflow. Creating a stand that will slightly elevate the laptop device will allow the fans to function at peak performance. You will only need approximately 2 to 3 centimeters of space between the laptop and the surface your laptop will sit on. It is also advantageous to create your cooling stand so that the laptop is slightly angled (between 10 and 15 degrees) to maximize the airflow while minimizing the distance from the surface.
Induction
Heat is actually the vibration of stored energy in individual molecules. With this in mind, induction works by providing a broader surface area for the heat to be dissipated. This is how a heat sink works, by increasing the surface area that the energy is transferred across. When choosing materials for your cooling stand, light metals such as aluminum are ideal because of the low thermic reaction threshold. This means that the heat energy will be transferred to the aluminum frame very efficiently. The larger surface area will serve to pull heat from the laptop itself, with the increased airflow the heat will be dissipated quicker.
Construction
The ideal form for a laptop cooling device will take the shape of a lightweight aluminum frame shelf. All the materials can be purchased at a local hardware store as well as the tools necessary (drill and bolts) to build. The laptop should rest firmly on the shelf without any clips or direct attachments to the laptop body. When framing the shelf, consider placing a crossbar that runs directly under where the battery rests as this is a significant source of heat. Additional bars can be added but should not be overdone as this may reduce the total airflow.
