For those of us who have had our service denied by Apple for whatever reason... there is hope. I went back under the hood of the machine last night and disconnected both thermal sensors on the machine (the one under the right fan and the one connected to the heat pipe). No more RSD in the past 24 hours. I'd like to add that the thermal sensor on the heat pipe had its wires TAPED DOWN to the heat pipe. This could be the reason for the problem, though I can't say for certain. If I go another day without a RSD and can be certain that it is indeed a problem with the thermal sensors on the MBP as well, I'm going to reconnect them but put the tape UNDER the wire instead of over it and see how that goes. Yes... the fans are on 24/7 now, and therefore it's really only a temporary solution, but to people who rely on their machine for work/school... it's worth it. Obviously I'm not recommending this to anyone who has done nothing that could potentially void their warranty... but if you have, give it a shot :] I'll keep you updated on the progress.
