"220V AC Cooling Fan" temperature Within a system, the cooling air required is inversely proportional to the amount of the allowable temperature rise. Allowable temperature rise slightly increased, to a significant reduction in the required amount of wind. Therefore, if allowed to impose the temperature slightly relax some restrictions, will reduce the required amount of wind noise can also be reduced. "220V AC Cooling Fan" Vibration Some cases, the weight of the entire system is very light, or the system must operate in accordance with the provisions when some particularly soft isolated equipment is recommended in order to avoid passing the fan vibration. Voltage fluctuation Voltage fluctuation will affect the noise level. The higher the voltage applied to the fan, because the speed increases, the greater the vibration, noise generation is also greater. Consider "220V AC Cooling Fan" design Each part design constitutes the fan will affect the noise levels. Consider the following design can be reached to reduce noise: the winding core size, blades and frame design and precision manufacturing and balance.
