CPU fan Power Greater heat dissipation effect is not necessarily the better

Theoretically analysis, fan power the greater the cooling effect should be better, but this theory is set up under a certain premise, that is, the fan power does not exceed the rated operating power of the conditions, the more powerful fan is usually the stronger the wind, the better the effect of heat dissipation. The fan power and fan speed is directly linked together, that is, the higher the fan speed, the fan will be more powerful.

At present, the general computer market is sold on the DC 12V, the power is from 0. x Watts to 2.X Watts, the power size of which needs to be based on your CPU heat to choose, in theory, choose a slightly larger power some better, because the fan speed is higher. But I also want to remind you here that can not be one-sided emphasis on high power, which needs to match the power of the computer itself, if the power is too large, not only can not play a very good cooling effect, but may aggravate the workload of the computer, which will produce vicious cycle, and ultimately shorten the life of the CPU fan.

Therefore, when we choose the CPU fan, we can not mistakenly think that the fan power is large its cooling effect will be good, but should be based on the principle of adequate to choose their own computer to match the fan.
