Under certain preconditions, the lower fan operating power does not exceed the rated operating conditions means that the power from the theoretical analysis, "Micro Cooling Fan" power greater the cooling effect should be better, but this theory is founded , the greater the power of the wind fan is usually the more powerful it is, the cooling effect is better. The "Micro Cooling Fan" of power and fan speed is directly linked, meaning that the higher the fan speed, the more powerful fan. Our customers in the selection of the CPU fan, not a misconception that "Micro Cooling Fan" power its cooling effect will certainly be good, but should be selected based on the principle enough to match with their own computer fan.
