I was wondering if anyone has experienced some sort of fan "clicking" with their rMBPs? Just tonight my computer has started making a noise from the right hand fan, as if the fan blades were gently hitting a small wire. The computer started making the noise after I brought it up a flight of stairs and set it on my desk. I carried it with the lid closed, sort of like a book. Using the app smcFanControl when I crank up the right hand side fan to high RPMs, like past 2500 the noise goes away. Any ideas? Thanks.
