"Waterproof Cooling Fan" the greater the power, the cooling effect is certainly better Theoretically, the greater the cooling fan power, the cooling effect will be better, but this theory is established under certain preconditions, that is said that in the operation of the fan power does not exceed the approved motion power conditions, the greater the power of "Waterproof Cooling Fan" usually it's the more powerful wind, thermal effects are better. Currently sold on the general computer market is a 12V DC power ranging from O to 2 watts, the power of which size you need according to your choice CUP heat is theoretically slightly larger selection of more power well, because this cooling fan inside pass rate is higher. But need to remind everyone here is not one-sided emphasis on high power, which need to work with the computer itself should match the power, if the power is too large, not only can not play a very good cooling effect, but may increase the computer's workload, which will produce a vicious cycle, and ultimately shorten the life of the CPU cooling fan. So when we choose "Waterproof Cooling Fan", not simply that the greater the cooling fan power cooling effect will certainly be good, and should be selected to match with their own computer cooling fan in accordance with the principles of good enough.
