iPad Pro iPad Pro left side heat?

Perhaps Apple has addressed this in the latest iPP hardware revision (see my post here).

The “enhanced thermal architecture” is about cpu heat dissipation, but we are talking about heat on the left side (probably near display drivers). Cpu is in the middle, not under the left side.

Same here the excess heat, Apple store swapped out my 11” Pro for a new one. Genius tech said it a known issue due to the cpu chipset heat not transferring properly to the back of the iPad Pro and spreading since that’s why the whole iPad Pro is one big Aluminium heat spreader. The cpu chipset has unattached itself or not transferring the heat so it just gets hotter and hotter instead of just warm and spreading the heat, which eventually causes throttling and slow downs.

Ah, I responded to you last year about this. I hope your replacement has continued to be okay. Bookmarking just in case the 2020 acts up.

The CPU seems to be more or less the same, only with an additional GPU core now activated, which is most likely due to yield improvements because of stabilized production process. Therefore my understanding of “architecture” would not necessarily be limited to the A12 chip only, but to a wider area. Perhaps they also optimized some power routings or used different parts that dissipate less heat (which could also include the parts on the left side).

And even if the reference would indeed focus primarily on the A12 chip: making it dissipate less heat would mean less heat in the whole system and thus more “headroom” for the other parts like the display drivers. After all, the iPad‘s heat sink (a.k.a. metal back) and its cooling capacity is shared by all components.

What I can tell you with certainty is that I tried a few days ago the new ipad pro 2020 at the apple store, and also the new ones all heat up on the left side.

I found this heat map of both ipad pro 2018 and 2020

Difficult to decipher. If I read correctly, the 2020 iPad is some 10 degrees cooler than the 2018? Is that correct?

do not look at the degrees, it was to show you that they both heat up on the left side.

Looking at the Ifixit teardown for the LCD there is clearly a board with 3 chips on the left side that power and control the LED backlight/LCD etc. When pushed to 100% 1 or more of these chips gets warm. As soon as I turn the brightness a little below 100 its no longer warm. There doesn't appear to be any heat sink or thermal paste on these chips so Ive come to the conclusion this is just the design. Just like when you run an intense game you can feel the back middle of the iPad get warm where the CPU is. Also the 120hz vs using 60hz might make a difference but I have yet to test it. Im not worried about it as its clearly by design and others stated they all exhibit this in the store where I'm sure they are cranked up to 100 knowing how blinding the lights are in an Apple store. I get a nice tan when I go inside .

The first part of your post is correct (ICs located there), the rest is not. Do not mix together the normal warmth development with single cases where very strong heat even under little use got reported. This also applies to several postings above, like the heat maps from Tommaso. We are not talking about the regular heat development.

Im not worried about it as its clearly by design

Nope. Read my description again: My got extremly warm, hot even, no matter if 60/120Hz or even at minimum brightness during idle. It wasn't any software issue either, as even after a complete Rest, the symptoms showed up after 2-3min in the "Welcome" screen. Gravis Germany has confirmed that I had a faulty unit, after dumb*ss Apple couldn't find any issue. My replacement is totally fine since then, just moderate warmth when working in Procreate, as it should be. Thus I encourage everyone with unusual/exceptional heat symptoms to consult an authorized service provider.
