I have a 13 inch unibody macbookpro bought about september 2009. The fan was acting up a lot so my son opened the case to replace it and damaged the fan connector and we had to remove the fan altogether since there is no longer any way to connect a fan. I doubt that Apple will help even though it has several months left in the 3 year apple care since we opened it and broke a piece off. My question is how hot can these mbp models run and be ok? If it gets up to 80C after a couple of hours and I close the lid, it goes back down to around 50C after a short while, so it's' not impossible to work on it. But how high can I let it get before starting to damage the hardware? Will it stabilize at some temperature if run without a fan? I took out the broken fan to leave some air space in the computer, in case that helps to cool it, and I have a small lap stand for the mbp that has a little fan that runs off a usb port, so it is never directly on a surface, but I don't know if it can run ok without a fan. Thanks for any advice.
