When the charger parts fall off, the charging parameters of the charger will be changed, causing the voltage to be uneven during charging, so that the temperature of the charger will rise, and the cooling fan will rotate abnormally, resulting in noise.

The addition of a breeze cooling fan in the charger can reduce the power consumption of the charger, and the module option does not require one-third of the fan power
The fan is loud, which is a normal phenomenon, because your mobile phone is placed on the wireless super fast charge that is to give the mobile phone wireless super fast charge and ensure that the wireless super fast charge will not be damaged because of high temperature. So at this time, the internal cooling fan will start to run at full power
