I'm seeing multiple CPU cores and the CPU PECI Die sensor reading 100C under high load, even with fans at 6000 RPM. Is this normal?
Got a tip for us?

That's insanely high temps but I'm not surprised. my 2015 rMBP with the quad core would run really hot if I used virtual machines. The 2016 is in a smaller/thinner chassis...less room. They can brag all they want about the cooling redesign, but I wonder.
I'm guessing there'll be some good thermal reviews of them out in the wild soon, comparing to the previous gen.
The first area to make note of when looking at the CPU tab in Activity Monitor is the table at the very bottom, where it states System, User, and Idle.
That whole area should be moved to the top, IMO, as a lot of people just initially zero in at that area of the window anyway, as that's how we read things. From top of reading area, to bottom. I don't agree with the placement on the screen of that info at all, but that's another topic.
Anyway, your idle was at over 60%. So, while it was about 30-something % busy, it still had a long way to go before it hit 100%.

It's normal if you have a bunch of background processes doing CPU intensive work. So, it depends. There's certainly not enough data in your post to definitively state one way or another though.

I think it's somewhat normal. Intel is known for higher-end models to consume a bit more power under load than lower-end ones (i.e. 2.6Ghz). I know 100C is disappointing given how the base model only reaches 88-90C under 100% load. However, these two numbers correlate well with what I saw in mid-2012/early-2013 machines.
Do you have dGPU activated? Even without load it'll add 3-5C to the heatsink / CPU temperature just by being on.
I believe it was using the Radeon GPU at the time. Unfortunately I'm going to have to take the machine to an Apple Store next week. It repeatedly freezes with this..
At least you have a beautiful pattern.... But seriously though, I'm sorry for that. Looks like some engineers screwed it up big time.
Yeah, the strange thing is that this happens on the Radeon graphics, but I still see mild flickering after I reboot and it's on the Intel graphics (according to iStat Menus). I see in the kernal logs that the Radeon GPU is resetting.
Looks like a deep firmware / driver issue to me. Hopefully Apple fixes the issue and you get a replacement just in case.
Checkboarding is a common symptom of GPU hardware failure. That's not something that drivers/firmware will be able to fix.
I've seen such a thing when I physically damaged one side of the display of previous rMBP - after hard reboot still image of before reboot, then it gradually slides away, works for several minutes ok and then fails again. What I mean is that probably the issue is not software-related.
I have the same Mac with the same problem
Please how can I use AM !!!

How can I know these things in the uploaded photo !!
I'm sure this easy question has been answered over the last 2 pages but couldn't be bothered to read through.
It's just indexing your photos, if you have a large library it needs to download and catalogue them all, and I'm guessing you've upgraded after having a machine for a while? (Hence you're unfamiliar with this). But it could also be transcribing them to a new file format.
Either way it takes several hours/days depending on the size on your library, this will use up a large amount of energy. Always check the AM and if it's hot when nothing running, then you've got a problem, otherwise it's perfectly normal and will go away once it's completed.
Also FYI. "Overheating" means it's shutting down, your computer's CPU can operate at up to 100'c and be fine, obviously that will be warm but it's not "Overheating", that's another specific issue.
