Loose screw / metal scraping noice, even after 4 repairs
When I bought my MacBook 3 years ago it made a strange metal scraping sound for a short while at the setup. But after that, I didn't hear it again until a year ago. It only appeared in specific situations (start of a Cinebench CPU test or when extracting a lot of small files like an update).
At the beginning of this year, I brought it to a certified repair center and they replaced the fan. When I came home and tested the laptop it still made the sound. So I took it back to the repair shop and the replaced my fan another 4!?!? times.
After those 4 times, I gave up on the repair process because I needed my laptop again. But the problem still persists. I have a recording of the sound.
The fans aren't the problem because when I run the diagnostics tool the noise isn't there. Does anyone have any idea what the problem might be? And do I have a problem if I open it up myself and take it to a genius bar anytime in the future?
Thanks in advance!
