I just want to see if other owners of retina macbook experience the same. I am not talking about fan noise. There is this really faint noise that sounds like it's reading hard drive. It happens when I scroll thru HD thumbnails (and it lags a bit during scrolling), searching spotlight, opening certain movies files. It's more obvious when the fans are at low speed (2000rpm) For retina macbook, can any other components make noise besides the fans?
