Tips for reducing noise from cooling fans

by:TOCH     2021-02-26
The noise level of the cooling fan is a knot in the hearts of the majority of users. No matter what the cooling fan is running, it will produce noise. The noise range between 0-40dBA is acceptable to people, and as the cooling fan runs longer and longer In the case of, the noise will gradually increase, so how should we reduce the noise during the use of the fan? u003cbru003e u003cbru003e u003cbru003e 1. In the initial selection of the cooling fan, the fan with low speed and large size should be selected as much as possible under the condition of satisfying heat dissipation. Generally, the speed is low, and the fan with large size can deliver the same air volume than the fan with high speed and small size. When the noise is small. u003cbru003e u003cbru003e u003cbru003e 2. The power supply voltage of the cooling fan is also the key to affecting the noise of the fan. The higher the voltage, the higher the speed and the greater the vibration, so the noise also increases. u003cbru003e u003cbru003e u003cbru003e 3. The airflow obstruction encountered by the cooling fan during operation will cause noise, especially the critical air inlet and outlet range, to avoid obstructions to reduce noise. u003cbru003e u003cbru003e u003cbru003e 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 reduced, and the noise will be reduced accordingly. u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e Thank you for your reading.
