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.

or you could just run smcfancontrol.

Thank you for not knowing anything about this problem at all.

Running smcfancontrol doesn't turn off the thermal sensors, it just lets you set the fans to what you want. It's not an overheating issue, it's a problem with the thermal sensors misreading either due to a short or thermal disruption of the signal in the wire.

having the fans funning full pelt all the time must have some effect on your battery life, and it can't be good for the fan motor.

I had RSD on my MacBook, i took it in to the Apple shop in the morning, and i had it back at the end of your day. i now have a MacBook which doesn't shut down randomly, and whos fans aren't spinning themselves into insanity.

oh don't worry his/her fans will burn out much faster now. They're probably running maxed out at 6 times the original speed, which isn't good.
I've read in other places that the smcfancontrol did fix their rsd problem. So thank you very much for being smartarse to a person trying to help.

I'd think having them constantly running would be BETTER than having them starting and stopping repeatedly. Typically, the stopping/starting is harder on the motor than having it constantly running.

close but no.

while starting and stopping is bad for a motor, the motor never actually stops. Doesn't matter what the temp is, the fans never ever go under 1000rpm.

the stopping and starting you refer to was fixed with a firmware update a while ago, so the fans no longer stop and start intermittently.
topping and starting isn't great for the motor, but running at ~6,000 RPM all the time can't be much better.

Links please... otherwise you're just a trolling in a post with an actual solution.

And you're not making any sense, anyway. "Six times the original speed"? As in six times zero? Because the fans start completely off. Good try with the pot shots.

This is specifically a solution for MacBook Pros that Apple refuses to acknowledge the problem in (i.e. they WILL NOT FIX IT FOR YOU -- for whatever reason).

This is all stated clearly in the original post.

do you even read? The fans never ever go under 1000rpm. Ever. Its hardwired into the computer. Just because you don't hear em doesn't mean they aren't going.

Nice, only if you actually read the things you post...
That's a page about MacBook RSD to begin with, and if you read the post in reply... chances are it's circumstantial evidence.

Those of us that actually have had the problem are well aware that it can happen while under a ton of stress (see: heat) or under none at all. Therefore ramping the fans up to keep it cooler isn't going to fix the problem (though it may result in less frequent RSD).

Now, if you'll please stop trolling unless you have something valid to contribute, it would be appreciated.
