For several years now my Macbook Pro (early 2011) has been rather noisy.
The noise has generally been intermittent, worsening with intense use, however recently it has become particularly bad and distracting. It is there from the second I switch the computer on and doesn't stop (though does vary in pitch and volume). I had originally thought it was a malfunctioning DVD drive (which hasn't worked for five years), and have tried to disable it to no avail, though I have set all options re the disk in system preferences to 'ignore'.
I am now thinking it could be the fan, though when I hear the fan kick in louder the whirring noise doesn't increase in sync so I am not certain. And even with very little running it is still rather loud. I have done an SMC reset. It's possible it's the optical hard drive but then I would have thought something would have gone more badly wrong by now if it was - given that the laptop has made these noises for the best part of half a decade.
The computer is running fairly slowly, despite only using 3gb out of 4gb RAM and circa 80% idle CPU
The in built attachment wouldn't let me add a movie recording of the sound - so please see the following recording: https://ufile.io/ibykvc7y
Any thoughts welcome before I take it apart and clean the fans - thanks.
