I have nearly identical MBP in 13 and 15". Both are specked out and mid 2014 but I had the 13" first. As many Macs as I've had, this is my first 15". I got it used but nearly brand new. It only had 3 battery cycles and absolutely no sign of use. In fact, it smelled brand new, in box, and even the Apple cloth was in the pristine black envelope. I heard of fans on 15" pros blowing like hell and it getting very hot. My 13 almost never had the fans high enough to hear. I was streaming a movie online and things got pretty insane. Is this normal? Right before the screenshots the fans were at over 5000rpms. This was a low quality movie in full screen. Graphics changing set to off. Thanks for any and all help. EDIT: Let me add that the other day when I had just gotten it, I got all excited and ran 3 external monitors with 4k video full screen at the same time and the temp was 85-90 with fans at over 5000. Seems normal to me. I was actually pleased. So for one low quality movie, this seems odd.
