First of all, understand the noise. The noise is caused by the vibration when the fan is running. Too much vibration will affect the working stability of 5g terminal equipment, and will also indirectly interfere with the equipment communication. Especially when small 5g terminal equipment is used indoors, the noise impact is relatively serious. The heat dissipating fan with good silencing effect is more important. While ensuring the heat dissipation effect, try to choose a low-noise fan.
As far as possible, PBT frame fan blades shall be selected as silent fan materials, which have smooth surface, wear resistance, embrittlement resistance, and toughness. Ball bearings are selected as bearing systems, which have stable noise value, unlike oil bearing, which has become more noisy and less durable after long service.
In addition, when matching more intelligent cooling fans with speed regulation, no matter 5g terminal devices or other intelligent devices, they all have no-load and load periods. The speed regulation fan can reduce the speed when it is no longer loaded, thus greatly reducing the noise value.
