Aluminum is widely used in the construction of CPU air coolers due to its many benefits. One of the main advantages of aluminum is its lightweight nature. This makes it easy to handle and install, reducing the overall weight of the cooling system. Aluminum is also relatively inexpensive compared to some other materials, making it a cost-effective choice for cooling components. The heat sink fins of many air coolers are made of aluminum. Aluminum has a high specific heat capacity, which means it can absorb and dissipate heat effectively. The fins are designed to increase the surface area available for heat transfer, allowing the hot air to be quickly dissipated into the surrounding environment. In addition to the fins, some air coolers may also use aluminum for the heat pipes or other components. Aluminum heat pipes can transfer heat efficiently from the CPU to the heat sink, enhancing the cooling performance. Moreover, aluminum can be easily molded and shaped, allowing for a wide variety of designs to meet different cooling requirements.
