Fan of large size can be obtained under the same rotational speed of the greater air flow, while the same amount of wind conditions, the fan is a relatively small size of the large-size fan can be kept more quiet.Many users are a big fan of the product has a unique feeling, so that the fan size became more and more users misunderstanding the bigger the better.
Big fan of the relatively small fan has some advantages, but we can not ignore the wind pressure for cooling, in addition to the additional effect of the air volume and mute, wind pressure is good or bad depends on the cooling effect, or the air volume and pressure has good cooperation we can achieve a good cooling effect.
Big fan of players who must be aware of the larger blades can bring greater amount of wind, often in speed will be reduced in order to achieve better acoustics. Large blades for wind pressure and did not play any role. From another point of view, high wind pressure radiator role can not be neglected, if the increase in the amount of wind, air pressure reduction, it is likely to lead to the radiator heat is difficult to be blown out. Then the fan turn enhance the cooling effect can be achieved, na 140mm fan with the turn enhance the degree of noise will soon be over 120mm fan, with the attendant noise will increase. Many vendors in the fan blade under the feet of the effort, designed to achieve better performance and cost proportion.
