How is this any different than any other mirrorless brands that don't have this problem? Also, you should set your camera to go to sleep after 1-2 min to avoid pointless battery wasting and rear screen-on time.
40 stills over the course of an hour with a 1min rest mode is as close to not even using the camera as it possibly gets. I would sure hope it doesn't overheat.
Well, as close to not using it is not really true at all. The sensor is actively being scanned and the LCD is refreshing constantly while it is on, which was for at minimum 40 minutes, which will generate heat on any mirrorless camera.
Now, this may be parsing close to the bone, but it doesn’t overheat doing this, it raises the temperature such that users can not shoot 8k oversampled footage or high fps video due to restrictions imposed by software, but I agree it makes the high fps and 8k oversampled modes nearly useless for any hybrid shooter.

You said in your previous post that power saving was set to 1 min. That means the LCD was not on for 40 min straight.

I have my R5. Tested stills by shooting 1500 exposures within a couple minutes (was testing buffer in both mechanical and electronic shutters). Camera was cool afterward. CF Express card was very slightly warm.

He said he took 40 shots, sporadically, in single shot, over the course of an hour, only allowing the camera to turn off the display and stuff due to the 1 minute power saver. It was definitely not on for 40 minutes straight, and maybe not a minimum of 40 minutes, but it likely actually was on for more than 40 minutes out of that hour based on the description of how it was used.

I think this is a good Canon release, but they underestimated the impacts of the heat cycling/cool down cycling impact on people. For still shooters, the camera is a beast.
I am beginning to believe that they are too conservative with the heating assessments. As I recall, Sony did this same thing a while ago. They eased up a bit and things were better.

I had an R5 for a couple of hours last week. Shot 8K/30 on a 96 degree Texas afternoon while standing in the middle of a 120 degree airport ramp area. The camera did not miss a beat. I'm not saying that it won't, but that was a pretty tough test. Great camera.

It's also possible that the "problem" manifests differently from body to body.
I recall after the 7D2 launch; Forum, AF complaints were at first, typically "written off" as being generated by Troll's, incompetents, and "Canon Basher's "; but so many followed that denial became futile.
I had mine back to Factory Service three times before they finally got it right.
It wouldn't surprise me if an unannounced modification took place, as the problem seemed to wane after some months.

Yes that is very possible too. That is easily fixed with a firmware update. I suspect they may find a way to add some video modes maybe that won't be so taxing on the processors as well, and we might get a big firmware update yet this year to fix/add these things.
I think I finally understand Canon's safety strategy with this camera....make the battery only last a few hundred shots...on top of that make it so the camera throttles the FPS at 60% charge to give even more motivation for the user to replace it early....last resort, just shut the camera down....end result....less cameras catching fire and turning into a Samsung problem

And I don't mind waiting a few months if they can fix a few bugs and make a near-perfect camera an inch closer to perfect!
I truly hope that they fix the problem if there is one. I think the R5 is a huge advancement for Canon and it is nice to see them pushing features aggressively again. I wish they wouldn't oversell features they know have limitations. Especially features 95% of buyers don't care that much about. This just unnecessarily gives the competition fodder to shoot at them. What I would like to see is someone really give the camera a throttling by shooting numerous long 20 fps bursts back to back to see if this causes the camera to overheat. Since we know stills shooting will effect video recording times I wonder if long continuous bursts can cause overheating in hot conditions. Overall, it looks to me like the R5 is a much better camera than I expected from Canon.

From CR:
"I have been told that Canon is actively working on solutions to increase record times and reduce cooldown times. What those solutions are is unknown at this point. I imagine part of it is firmware, but are they also looking at a hardware fix?
I have no been told a couple of times that the 2nd allocation of camera bodies will be delayed. Adorama told me it was going to be a significant delay, but that they didn’t know why or how long the delay would be."

If I were in the Canon IT department, I would have every bit of code checked over regarding video to see if there is any way to improve memory usage and processing, threading, and file I/O. I am not sure if they used some sort of standard libraries and packages, or built their own, but I am sure they are mulling over every function call to see what can be done to improve the process. Also, it may not just be code around video. If the camera heats up just in general use, there may be other things they need to look at like the video mapping to the EVF and rear LCD, and things like that.
That is first and foremost to trying to solve the heating issue. If they find nothing, then they will likely have to do a hardware fix, which requires a recall. That would be the last thing they do though, they will try everything else first, even cooling devices that you mount like a lens cap, that EF adapter cooler they filed a patent for, etc.

Ever watch the movie Apollo 13?
All the variations they tried to save the few extra amps needed.

Has anyone tried to cool the beast down by removing the lens?
I think some have but haven't read about any real success with that. You would think it would help to some degree. However, it seems that this camera is so sealed that external heat doesn't seem to make things worse but on the flip side cooling it externally doesn't seem to help it cool down faster either.

One of the reviewers removed everything possible and said it didn't make much difference. IIRC he said nothing removed at overheating was particularly hot
