UPDATE #2: I made a video... hope this helps explain things clearly. UPDATE #1: I just looked at everything more and the issue pretty much has everything to do with the Apple Smart Keyboard and NOT the iPad by itself. After further examination, the entire spine of the keyboard that is the same length of the iPad and is where the smart connector is located is a magnet.The magnet is easily strong enough to support the weight of the iPad and is what has caused this issue. ****** Just got my replacement 2.9/460/1TB machine yesterday (graphics issues), and I was on my couch setting it up and playing around with some stuff. So far so good. I had to get up for a second, so I set my MBP down on on top of my 9.7" iPad Pro, which was laying next to me protected inside the silicone back cover and keyboard front cover. I immediately heard this HORRIBLE grinding sound. My heart sank... It sounded like the fan and my first reaction was a sudden hardware failure. As soon as I picked it up, it stopped... I set it back down and it started again.... so I was like, WTF is going on here?!? After a mild heart attack and some adrenaline powered deductive reasoning, I figured out that that the magnets used in my iPad and the keyboard cover had enough strength to pull at one of the MBP fans through the chassis and cause the fan blades to hit the chassis and make a grinding noise!! UGH. Definitely relieved it wasn't more serious than that and glad I caught it before I walked away, causing the fans to burn out... or even worse. It was a lesson learned for me, so I thought I'd pass it along to anyone else as a warning... keep them away from each other! Cheers.
