So, I have been thru a numbers of Surface Pro's by now. (for various reasons) and I insist on loving and using this machine, but.... The one I just got has a higher pitch noise/tone than usual (coming from inside the chassis, slipping out thru the top and bottom right side). Apperently it's a c-state issue and the other one I had became milder with 8.1 (making it bearable). Yet this one, no change, higher sound. It is incredibly annoying. I know there was a HOT FIX posted by MS some time ago, but that doesn't work. So... is there anyone out there who has a fix for this? Cuz it is killing me and my fragile head.
