Why does my MacBook fan sound loud and cause vibrating?
I have a 2.4 GHz (A1278) MacBook Unibody 13" with a really loud fan. Sounds like something is scraping and it vibrates. It's really loud even when I'm not doing anything on the laptop. Everything works fine except my fan noise/vibration.
Note: I opened it up, and cleaned out all the dust and it looks perfectly fine. Nothing is caught and I cleaned out the dust
Please help me with these questions.
Do I need to replace my fan?
Is it safe to use when it's so loud and vibrating?
How do I fix it? Any troubleshooting suggestions?
