I used to had a smelly MacPro2,1. Called AppleCare, sent to 2 service providers. Changed PSU and CPU heatsink thermal paste, but never did solve the problem. Contacted AppleCare again, this time sent to a different service provider on the suspicion of melting rubber issue (yes, MacPro2,1 is one hot machine), hence have to replace the entire enclosure, logic board mount and all that jazz. Parts were ordered, but the service provider was incompetent enough to reassemble it, end up the entire unit failed to power on. Finally Apple decided to replace with MacPro4,1, resulted in one freaking month without a Mac Pro to use. Now I've got all those redundant FB-DIMM modules laying waste.![]()
So you have AppleCare for your machine ? Mine is out of warranty.
