"Micro Cooling Fan" fin structure even more complex, it is only a passive heat exchanger; therefore, an air-cooled radiator whether normal "work" depends almost entirely on the fan working condition. Without altering the structure and other components of the radiator, the only replace more appropriate, powerful fans, so that the cooling effect can also be obtained greatly improved; the other hand, if the "Micro Cooling Fan" with inappropriate or not strong enough, it would be greatly reduced the effectiveness of air-cooled heat sink, so that the heat sink and the overall design of the advantages of being buried in the invisible; more, due to the "Micro Cooling Fan" is the only air-cooled radiator indeed part of the "work", it also can lead to failure in itself the whole radiator failure, so that it lost most of the thermal performance, thereby causing system instability or crashes, or even due to high temperature burning equipment.
