1. What is the reason why the hot fan does not turn?
There are many reasons why the cooling fan does not turn. One is that the fan is broken, and the other is that the power supply is broken. However, under normal circumstances, the fan will not break, because the cooling fan works at high temperature for a long time, and it is easy to dry the lubricating oil of the fan. You can try to turn it by hand with the help of external force. If there are signs of fretting or great rotational resistance, it means that there is nothing wrong with the fan, but the lubricating oil is dry. You can remove the fan and generally stick a sticker on the back. You can take it off, and then you can see the shaft of the fan, add some oil or something, and turn it by hand a few times, and you feel no resistance. Reinstalling it should solve the problem.
