Micro Cooling Fan temperature upgrade issues

Vibration can cause the fan noise increased, reduced life expectancy and reduced speed. In operation, since the current through the fan coil wire is resistance, it will inevitably produce an exothermic heat outward, so the temperature will rise. But why people feel cool it? Because the human body surface has a lot of sweat, When fans work together, indoor air can flow together, so we can promote the rapid evaporation of sweat, reduce the temperature difference between the temperature rises, the cooling effect is reduced. Vibration can cause "Micro Cooling Fan" noise rise, life and reduce speed to reduce.
