Buzzing, grinding noise coming from rear and centerish?
My macbook pro has started to make this super annoying grinding noise, that sort of sounds like a small(toy size) electric motor, which made me think that it must be the fans, as when it was really bad the computer was also uncomfortably warm.
So thanks to this site I got the tools needed and opened up the back removed the fans and cleaned them with a toothbrush and some canned air, but sadly the problem persisted, so i thought it must be the HDD, so I ordered a new HDD (hybrid 1tb) and put that in, which didn't help and leaves me 200 dollars poorer. I have tried to look online but it is really hard to tell if their sound is similar, which is why included the audio link down at the bottom.
The noise seems to be coming from underneath the 'Y', or at least when the noise happens I can feel vibrations strongest from the Y key. Please Help
