220V AC Cooling Fan speed and size

Due to the high speed "220V AC Cooling Fan" greater than the low speed fan noise, 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 fan when transporting the same air volume. "ios版雷竞技官网入口 " temperature within a system, is inversely proportional to the amount of air required for cooling temperature and allowed. Allowable temperature rise slightly increased, to a significant reduction in the required amount of wind. Therefore, if "ios版雷竞技官网入口 " impose the allowable limit temperature rise slightly relax, will reduce the required amount of wind noise can be reduced.
