First thanks for the kind words TapTap.
Yes it's frustrating DBounce I get it trust me.  My iPhone1 used to drain power. My D90 looked like Jello mold. My 7D would randomly corrupt clips and the same for three of my friends. The 1DC has crashed on me. Reds software would freeze up mid shoot..... Early adopting any product comes with the landscape of stress. I don't like it but I'm interested in this camera for the same reason everyone else is. The 1DC is priced out and you want a dslr solution in 4K. 
I'm not saying in anyway Sony gets a free pass, all I wanted to say is that if your committed to the A7Rii as your main camera there are some work arounds  if needed in a jam. Otherwise return it and go back to your camera that works for how you make a living. For me it's to volatile in 4K so I have to pass for now on using it for gigs. 

So first off I come from Live Events so my testing of the A7Rii falls into the pocket of shooting all day 1-8min clips and not getting a second chance. For that reason I am going to say upfront I would never walk into live event without a second body strapped to my hip especially with this hot 4K little monster. Now I shoot 1-8min takes because I lived through the 7D days of clips deleting at random so honestly I shoot smaller sized clips based out of habit. Even for toasts etc, we have multi cameras running so its no biggie. 
So I decided to run the new camera until I got the notorious temp icon of dread..... My take on that moment is what if I was on a  shoot how would I adapt aside from dipping the camera in ice or holding a cold beer to the of the back screen. 
Shooting 4K 100mbs FF 3200ISO Image Stabilizer On
 I received the temp icon at roughly the 25min mark shooting 3-5min clips back to back. I quickly switched the battery out and than decided to use just use the viewfinder(not as heat heavy on the camera). I was able to from that moment shoot 3-5min clips for 40minutes without a single warning. I also switched over to S35 somewhere in the middle just to see if it would heat things up. Total Runtime was 65minutes without having to shut down /cool down. If my card did not fill up I would have liked to go even further.
I know its not ideal, but if the moment presents itself swapping a battery and switching viewfinders is a whole lot better than waiting for the camera to cool off. This also does give me hope on the A7Sii body re design to fix the issue as its lurking around the screen more than the sensor.

This.  I had a strong hunch it'd overheat.  My RX100 overheated, my NEX 5n, NEX-7, etc.  I remember 4 years ago going to Florida with the 5n - in 93 degree temps it would only shoot about a minute of video.  Lost some precious footage / shooting opportunities of my kids.  Yes I'm still bitter, and yes, reliability trumps all.

This was a great post and just on the heels of me pre ordering the A7R ii after being a huge canon user and also fan of the 1DC....... it makes me sad to leave canon and I hope someday i can comeback. they just never went between the 5D and 1DC for something special...... I mean they didn't even add Clog to its latest round of DSLR updates so i can B cam off the 1DC if needed..... It screams we don't care about what you need.
