"220V Cooling Fan" will have a direct impact on the cooling power, it is beyond doubt, but the power supply fan size is also very important. Today small cooling fan on the choice of several recommended for everyone. Check the fan detection means foundation, "220V Cooling Fan" must have enough intensity and rigidity to ensure fans can tolerate the weight of the runtime, the same connection size at the right time with the cooling fan detection checks whether the foundation planned to meet the request. Brushless DC fan of all kinds of technologies are quite mature, each design can only be improved with producers and improvement on this basis, if there is no major scientific discovery, driven by short-term "220V Cooling Fan" work form and performance will not be a big change.
