It’s almost as if it’s so consistent that it is a software limitation...

I agree. I bought a Ninja Inferno to deal with the occasional video use I might try with the R5 (but no 8K or 4K 120p), but otherwise it's strictly for stills. Despite that, there must be a fix to make this more palatable for others AND stop all of the negative PR Canon is getting. Maybe third party solutions like the Tilta will help as well, but they need to step up quickly and back up their claims with real world tests.

Idk but it's heat and it has to dissipate somehow. I just don't see how it is staying hot so long. Should be a way to dissipate it, either by pulling the card and putting it in your hand etc or putting it in the fridge. About the same as going outdoors in winter but I'd probably put it in a plastic bag, removing much of the insulating air.
I was headed towards getting into astrophotography. One camera advertised 40° C below ambient I believe, probably to limit noise on the long exposures. So it might be worth calling OPT or signing up for an astronomy/ astrophotography site and seeing if they have any solutions.
And if you can figure out the source it's not a bad idea to try to heat sink it out somehow. Aluminum and even copper pieces aren't necessarily that expensive. Might even try an old penny. Probably not the best but Cost: $0.01

Yes it seems very software based. I was watching the YouTube video from the guy who discovered the 4KHQ external solution. He said after the 4hrs he got doing external that the battery wasn't hot at all and no real heat could be felt from the camera. And yet it did shut him down at around the 4hrs mark. He also believes that if he hadn't turned on the LCD at that point that the camera wouldn't have shut down. All seems to be some overly restrictive software that may be a good thing because Canon can likely tweak it and still not have heat damage to skin or camera.
It seems the CFe card is a big factor in all of this.

Easiest way to determine for sure is for the testers to take test photos before/during/after video thermal shutdowns and examining the temperature in the EXIF.
8K restrictions are fine, as this is not a professional 8k camera, only an added good to have feature.
But 4k restrictions and heat are simply unacceptable at this price when competition has gone way ahead and improvised on all shortcomings. What is canon doing, maybe hear customer feedbacks and learn from mistakes.
Totally agree! 8k is a novelty, the 4k issues are going to sink this camera rather fast if not handled. The output is great, such a shame

It is talking about the heatsinks being aluminum vs copper, not the wiring. Aluminum is fine for conducting electricity in your house, it is the connective points (ends) that are the issue. Many houses have added copper ends to their alum. wiring which then connects to the boxes, etc as a way to not incur so much cost pulling all the wires and replacing with copper during renos.
In relation to heat sinks though (heat dissipation), copper is about 70% more thermally conductive than aluminum.

People always complain anyway. And even Sony had overheating .. and the A7S iii does too, to some degree. But as the heating videos triple or quadruple, so to the testimonials that the R5 is an incredible machine for photos, virtually matching the A9 ii AF and A7R iv for low light performance.
That's a 400% .. maybe even 800% ... boost in positive testimonials about the main things MOST photographers were wanting beyond the EOS R. Two cards, preferred controls and a bit more in AF.
Add all that up, plus recent reports the R5 can do unlimited 4K recording with an Atomos ninja, and it looks more like your comment gets trapped.
Canon can look so small and trapped when we inflate our opinions.
When you cannot just switch over to do video as you are doing stills, the external recorder comment is crap.
a) Only a dedicated video shooter is interested in the external record and 4K, ain't nobody else giving a darn about that because they aren't going to pull the cards out and attach an external recorder, because then they cannot shoot stills.
b) Canon marketed (and raised the price accordingly) because this is an 8K video shooter. But alas it is very, very limited in that regard to almost being non-existent, and even with an external recorder, you are hosed. I suspect there several EU consumer protections that will be utilized to send things back, because Canon advertises something that cannot be realized in everyday shooting, and that will fail some of the consumer warranty regulations.
So many folks are left feeling pretty bad that they have to spend this for what is supposed to be an 8K video capable camera and quite frankly it isn't, and to boot, the stills side has some risks as well when it comes to overheating. So not only are you paying for video with this camera, you are paying for video capabilities that aren't really there in day to day shooting as you need it without going through hoops like 2-3 hour cooldowns, external monitors attached to your camera, etc.
It feels like we have some Canon marketing folks here on FM, doing their part in the ol' Jedi mindtrick "This camera is fine for your needs"...

Some folks feel bad too when they buy a Corvette or CTS V capable of maybe 140 mph, but have to live with speed limits of 75 mph on many highways.
Most of society is accustomed to products becoming less than antipated, or capable of more than they are allowed.
The solution is really easy though. They can buy another body or sell the one they have. The solution is so easy, and the body so far beyond expectations of many for stills, there's little real consequence.
With short supply, almost anybody could sell the R5 and break even or make a couple hundred dollars.
But why would canon not want to fix it and not have all the video shooters leave and go to Sony? That was their whole marketing campaign...
The stills side is amazing yes, but it’s literally the only camera I’ve ever shot with that can’t get me though a shoot of photo/video... that’s not good at any price. The hybrid video/still market is huge and it will overtake the photo only side very shortly.
Nobody asked for 8k.... we just want 4k that doesn’t overheat, or cools down way faster .... like every single other modern camera , even the 1dxii and 3 wont overheat in 4k 60
