Micro Cooling Fan selection

One "Micro Cooling Fan" radiator products, though far from capacitors and resistors and other components, but the selection of the heat sink material is also an important factor affecting the cooling effect. Most commercially available CPU fan, with the "dota2雷竞技预测 " fins generally use aluminum production (aluminum due to insufficient hardness, it is difficult for cutting). This is because the aluminum processing, and surface treatment easier (for example, grinding and cutting and other processing), and low cost. "dota2雷竞技预测 " copper or copper alloy is heat sink selection scheme can be considered another set.
