Fan "Inflatable Air Blower" belongs to a class of humble all computer accessories. But necessary. An excellent performance of the cooling fan can satisfy the needs of computer hardware cooling. Became the patron saint of the stable operation of the computer. To a strong performance cooling fan. Fans overall processing required on all the details just right. To achieve the best performance. Air volume of the "Inflatable Air Blower". Pressure will be sacrificed. Pressure big wind volume will decline. Cooling fan speed and cooling capacity and not necessarily related. Higher cooling fan speed but will bring more noise. When the speed has reached the limit, to increase the amount of wind, the only way to change the blade angle or increase blade fan proportional to the number and amount of wind. But the number of blades is not possible, be based on the needs of air flow pressure to consider "Inflatable Air Blower", the high amount of leaf windy while the fan noise will naturally increase;
