Cooling Fan Noise Reduction Tips - The size of the cooling fan noise is the majority of the user's heart pimple!

The size of the cooling fan noise is the majority of users of the pimple in the heart, no matter what cooling fan operation will produce noise, between 0 ~ 40dBA is acceptable noise range, and with the cooling fan running longer and longer in the case of the noise will gradually increase, then in the process of using the fan we should be if the noise reduction it?

1, cooling fan in the initial selection, in order to meet the case of heat dissipation as far as possible to choose a low speed, size of the fan, the general speed of low, large size of the fan than the high speed and small size of the fan in the delivery of the same amount of wind when the noise is small.

2, cooling fan power supply voltage is also the key to affect the fan noise, the higher the voltage, the speed will increase so the vibration is also greater, resulting in increased noise.

3, cooling fan encountered in the operation of the airflow obstruction will produce noise, especially critical inlet and outlet range, to avoid obstruction to reduce noise.

4, cooling fan in the cooling of the required air volume and the allowable temperature rise is inversely proportional to the allowable temperature rise slightly increased, it will be a large reduction in the required air volume, so if the imposed allowable temperature rise restrictions slightly relaxed some of the required air volume will be able to reduce the noise and also reduced.
