Micro Cooling Fan shape

We mean "Micro Cooling Fan" shape, usually refers to the shape of the composition of the fan heat sink. Due to the shape of the fan inlet and exhaust a great impact, and inlet and exhaust will be directly related to the final cooling effect, so in a sense, "Micro Cooling Fan" in the performance of the fan shape also has some influence. More upscale fins using aluminum mold formed through lathe, turning the shape of a plurality of cylindrical projections was after this heatsink used on high-end graphics and some foreign original machine's CPU (there are many foreign original machine simply do not use a fan, use only this heat sink). There is also a fin-shaped "Micro Cooling Fan", is formed by bending the thin aluminum, it looks like accordion bellows, the cooling effect of this fin-shaped heat sink well.
