Disassembly and repair and replacement of the fan bearing 624z. The fan worked for more than 5 years and the bearing hummed. I myself found how to fix it on only one resource, but I did not find a video on RU-vid. Although initially I also looked on RU-vid, unfortunately, only empty reviews.
See fix it and you will succeed!
As I did ..)
Write if the video helped you and fixed your fan.
God help and remember
