Reasons for affecting fan noise
The noise generated by the cooling fan during operation is influenced by various factors, expressed in decibels (dB).
When the noise of the radiator fan is less than 20dB during operation, it is a super silent fan. When the noise is less than 40dB, it is the sound level that everyone can accept when it comes to sleep quality. So what are the hazards to the noise level of radiator fans? Let's give examples one by one together.
1. Cooling fan bearing system: The noise level of the general bearing system is the highest generated by double ball bearings, followed by hydraulic bearings and oil bearings. The reason is that the friction and collision between the rotating shaft and the bearing during the operation of the cooling fan are the main factors affecting the fan noise.
2. Cooling fan speed: The higher the cooling fan speed, the greater the air volume, and the greater the noise. We cannot overcome this problem, we must rely on the actual cooling needs of the equipment.
3. Installation method of heat dissipation fan: When installing the heat dissipation fan, ensure that there is sufficient space between the fan and obstacles, and installing the heat dissipation fan without space will increase the noise.
