I will start this thread based on the old one which can be located here: http://en.miui.com/thread-1337837-1-1.html
For some reason, I was redirected here upon placing a new comment on the orignal thread.

Does anyone who owns a Xiaomi Mi Notebook Pro 15 still experience the ratling noise on both fans? I have this notebook for a year now and so far these are the things that I tried to remedy the issue:

***Please note that these solutions are based on the post of other people on the original forum: http://en.miui.com/thread-1337837-1-1.html

- Clean the fans (went silent afterwards even on load but after a few hours the rattling returned)
- Use oil/grease to lubricate the fan blades and the face casing aroung it (worked like a charm and no noise. After 2-3 weeks the rattling returned)
- Place some electrical tape cutouts on the screen area of the fan cases to "lift" it and prevent making contact to the fan blades (rattling noise is still there)
- Bought replacement fans (not the metal ones) at Alibaba based on the links posted from the original forum. (rattling noise returned after 1 week)

Until today, the rattling noise is still present on my unit and I am hoping that someone may have already found a PERMANENT fix for this issue. Any replies would be appreciated.
