In fact, the "Inflatable Air Blower" placed horizontally on top of the heat sink, so it can wind blowing straight down on top of the heat sink. Now the market's bias radiator fan powered by a turbo, so again it is called "turbo" or "Tornado." Advantage is the ability to eliminate the traditional overhead fan brought wind blind and turbo "Inflatable Air Blower" wind evenly distributed, with lower fan speed to produce a greater amount of wind, effective control of the noise, while achieving superior heat dissipation efficiency. But the disadvantage is that the wind speed is relatively low, so the heat slowly. Cons: Although it is opposed to the lateral side-mounted volume has been effectively controlled, but flat turbo "Inflatable Air Blower" coupled with the heat sink head is too high to increase the weight of the radiator attendant barely touches accepted.
