Because "Tiny Cooling Fan" shape of inlet and exhaust a great impact, and inlet and exhaust will be directly related to the final cooling effect, so in a sense, the cooling fan to fan shape work Performance also has some influence. Common heat sink is to compression, a common shape just a few more leaves, "leek" shape, this "Tiny Cooling Fan" cooling effect is most common. 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). "Tiny Cooling Fan" There is a fin-shaped heat sink is formed by bending the thin aluminum, looks like accordion bellows, the cooling effect of this fin-shaped heat sink well.
