Is it normal for the camera fan of 4223 ball machine to be loud?
The camera fan sound of the 4223 ball machine is very abnormal. When the camera is turned on, it will hum because the cooling fan is out of order. The system equipment of the camera is ventilated and cooled by a small fan. If there is a buzzing sound after the power supply is connected, it means that the central shaft of the fan lacks lubrication for daily maintenance and there is a friction fault. It can be disassembled and dripped with lubricating oil on the bearing to solve the noise problem.
