DC Cooling Fan Interface

Tips: Factors affecting the noise of DC cooling fans
1. Speed. The faster the DC fan rotates, the bigger the fan, the louder the noise.
2. Bearings. The bearings of DC fans are briefly divided into two types, one is oil and the other is ball. Under normal circumstances, ball bearing fans are more noisy than bearing bearing fans.
3. Airflow. During the rolling of fan blades, they will encounter resistance in the air. The faster the rolling speed, the larger the blade area and the greater the resistance, so the noise will be greater.
4. Conflicting force. If the fan is used for a long time, the fan will be excessively racked, vibrated, and the center of gravity is unstable. This will cause a collision or conflict between the fan blade and the fan frame, and then generate noise.
