I had the same response, maybe we'll have to wait 'til 27th before UK goes live.
My 2012 15" rMBP didn't show those issues YET but the fans were spinning like crazy upto 6000 rpm when doing anything remotely taxing, even playing youtube videos, SMC Fan Control app showed internal temps upto 105 CENTIGRADE, I went back 3 times, had a new fan, then a new logic board, still no improvement, It got so I wouldn't use it, eventually tested a 2013 model which ran many degrees cooler running the same apps from a cloned ssd of my drive and that was enough to convince me to replace my machine myself.
I now have a later spec 2013 version of the same machine and it's 40-50 degrees cooler. Tell me that was not a problem!
I'm out of pocket by £100s on this not to mention al the time I spent on it.
Not Happy
