The noise level of the cooling fan is a concern for many customers. At present, no matter what the fan is running will cause noise, the acceptable noise the human ear between 0 ~ 40dBA, beyond this range can cause discomfort to the human ear , and as the cooling fan operating time increases , also noise It is gradually becoming more and more obvious , so we can take the following four methods to reduce noise during the use of the fan !

1. In the initial selection of the cooling fan, a fan with a low speed and a large size should be selected as far as possible when the heat dissipation is satisfied. Generally, the speed is low. A fan with a large size is more noisy than a fan with a high speed and a small size when delivering the same air volume. small.

2, the power supply voltage level of the cooling fan also will affect the fan noise, the higher the voltage, the vibration speed will increase greater, therefore causing noise is increased.

3. The airflow obstruction encountered by the cooling fan during operation will produce noise, especially the critical air inlet and outlet range, to avoid obstructions to reduce noise.

4. The air volume required by the cooling fan for cooling is inversely proportional to the allowable temperature rise. A slight increase in the allowable temperature rise will greatly reduce the required air volume. Therefore, if the restrictions imposed on the allowable temperature rise are slightly relaxed, the required air volume Will be able to reduce, and the noise will be reduced accordingly.

So choose a good cooling fan to avoid many unnecessary failure occurred, Silversea Electronics is professional development and manufacture of DC cooling fan, AC cooling fans, blowers ...... manufacturers, with more domestic quality products and The service can provide you with a complete cooling fan noise solution.
