"Micro Cooling Fan" power is the influence of the fan cooling effect of a very important condition, the greater the power of the wind is usually the more powerful fan, the cooling effect is better. The power and speed of the fan is directly linked, ie the higher the fan speed, "Micro Cooling Fan" is also more powerful. Currently sold on the general computer market is a 12V DC power from 0.x to 2.x watts watt range, depending on your needs when buying CPU heat to choose, in theory, better power slightly larger some, however, can not be one-sided emphasis on high power, if power is too large may increase the workload on the computer, thereby adversely affect the overall stability of the "Micro Cooling Fan".
