Just got my 2015 MBPr 2.9 8g 512 All I've done is email and surf the web and it's super hot. My wife's 2013 MBPr is cool as a cucumber doing the same thing. Mine is too hot to keep on my lap. Mail, chrome, evernote are the only things running, plus dropbox in the background. Fan alternates between running slow and approaching liftoff speed. Never just off. No problems with my 2014 11" Air that I just replaced. Any ideas why this is so freakin hot?
