24V DC Cooling Fan speed and size

Due to the high speed "24V DC Cooling Fan" have a greater noise than the low speed fan, so you should try and use low-speed fans as possible. And a large size, low speed fan, generally, quieter than the small size, high speed of the fan at the same air volume delivery. "iphone下载雷竞技 " temperature within a system, inversely proportional to the temperature required for cooling air flow and allowed. Allowable temperature rise slightly increased, to a significant reduction in the required amount of wind. Therefore, if "iphone下载雷竞技 " impose the permitted limit temperature rise slightly relax some, will reduce the required amount of wind noise can also be reduced.
