I suspect we might be seeing some cooling kits coming out soon

Fascinating and brilliant if I do say so. It's indeed a shame Canon didn't opt for a thicker COPPER plate with more coverage as he did. As that alone took care of the record limiting without even going the extra distance of water cooling. It wouldn't have taken much. But like he said it was a matter of priorities. I suspect later models may well incorporate this type of application. Good thing I don't do video however so it doesn't bother me.

Yeah I kind of said this from the beginning. But many out there do serious video and demand a "do it all" camera. They assumed the R series would be the answer to that.Still?????? It's not a problem. It runs exactly as designed by the manufacturer. If anyone needs professional recording times buy a dedicated professional video camera.

Great video. Hard to believe he put so much time and effort in the modification. I'll never use over a couple of minutes of video at a time on y R5 and then not 8k.
Thanks for sharing.

If this guy can fabricate a part by hand and fit it to the camera and it works, then Canon could have EASILY solved the overheating problem of the R5. All it would take is to design a heat tube to route heat to an external surface of the camera. This is done in smartphones as an afterthought. It looks to me like the lack of applying effective heat management was intentional because the engineering and cost to add this type of cooling system would be minimal. Especially if a guy with hand tools and limited resources can do it.
It is Canon's prerogative to limit capabilities of a camera if they choose. What irks me is how this camera's video capability was up front and center in the marketing effort. They used its video prowess to entice people to buy the R5. The R5 is a very good camera but $10 worth of parts would have let it live up to its billing.

Clearly, Canon was not trying. Maybe to create a difference for their video-centric models or maybe they were in a hurry. But the whole 30-minute limit makes it look like a poor design.
There are better materials than copper these days for heat transfer such as Panasonic's PGS. As the video shows, you still need to have a way to remove the heat after it is transferred. My guess is that instead of adding a fan, they could have gotten away with a passive addition to the bottom of the camera.

Also did you not read Roger Cicala's (Lensrentals) forum posts and his teardown that this site hosted?
I again encourage to modify your 5R's and run then to the max. If you don't stop trolling.
Cards, software and computers that can handle it. $20,000 later will you get your 1 hour of 8K uninterrupted whatever. :-D

The other stuff isn't involved in the overheating.
I admit I only skimmed the video but if you watch the external recording videos it's clear a big heat source is writing to the cards. He seems to be claiming unlimited 8k recording which to test requires currently unavailable cards.

One way is to record until the card is full, format the card and start recording again. This would be a break in recording of only 30 seconds or less which is negligible to the purpose of the exercise.
A lot of people will modify their R5s. Count on it. I expect this mod will eventually be offered as a service by a few places. How is the content of this video been "trolled to death" when it was uploaded yesterday? This guy is the first I have seen take this type of approach for a cooling solution. I can see where this approach can be further refined and be done for low cost while still retaining weather sealing and no external modification to the shell being necessary. In fact, I say this guy's work shows without a doubt that Canon intentionally decided to not address the R5s heat issues. Especially so considering the simplicity and very low cost of his solution. Canon can design a complicated device like the R5 and then fail to add $10 worth of parts that solves a heating problem they knew existed? Canon's engineers aren't this incompetent.

I meant this subject was trolled to death. I will bet unless you are pro and/or have money to throw away very few people will modify their cameras during the warranty period. Then you have the people who have extended warranties. Those are all void if you modify the camera in any way.
Then rule out people who don't want fans to suck dust into their cameras and lose weather proofing. Like Roger Cicala said. There is a reason why professional video cameras have heat sinks that weigh as much as the R5 itself.
I don't consider it trolling when a person makes a discovery regarding the overheating issues that hasn't been presented before. What the person in the video has done is unlike any previous attempt I have seen. He presented an internal fix that is relatively simple to apply and keeps the camera's stock weather sealing in place. Then it can be enhanced with fairly simple external measures to allow unlimited recording times. This type of modification will be a welcome addition to people who have a need for high quality video and need/want to get it from a capable stills camera.
Roger Cirala will have a hard time explaining why he wouldn't expect Canon to have applied such a low cost, simple and effective cooling measure to a $4k camera. Especially one they touted as being a video juggernaut.
This just smacks of Canon again gimping a camera to protect their Cinema line. The thing that really irritates me about this situation is Canon coming out and saying they had heat issues and this is why the 8k and HQ 4k is so limited. In reality it appears they either created the heating issue or intentionally decided not to handle it with a simple, cheap effective fix. Instead, they released a firmware update hoping it was enough to tamp down the complaints. If this fix gets refined, applied to a lot of cameras and is highly effective, I predict Canon is going to take a serious hit to their integrity over their deceptive actions and comments.

I too was a bit surprised in Roger's tear down that Canon just used some flimsy pads to begin the heat absorption process. Someone posted some very inexpensive carbon based product that is better at dissipating heat then even the copper. Sheesh perhaps the Canon engineers need to sit back down and rethink this a bit next time. Surely they can't have a issue against anything that might assist the process of the heat dissipation in the future. Imagine if they did this in the beginning and one could use the 8K recording for a few hours without issue? That would certainly have shut up the world of folks complaining. But then if they bought a C300 video recorder AND a R5 they would also have shut up. But noooooo they just need something to beef about it seems. Just because Sony can go longer doesn't make it a superior all around product IMHO. Otherwise I'd have bought one.
The issue for me is that if the solution in the video is as effective, cheap and easily applied as it appears to be then Canon's engineers need to be fired for not adding something similar to the R5 and R6. I am an engineer and I doubt Canon's engineers are this incompetent. I would bet a large amount of money that this fix was presented by the engineers and it was too effective for Canon's bean counters to allow into the camera for reasons of protecting their Cinema line of cameras. This is fine but Canon lying to us about the heat issues being to hard to overcome is not fine with me and probably many others. Especially if this fix becomes more refined and popular with R5/R6 owners. This could be another looming PR disaster for Canon.

The problem that remains is the other videos on external recording clearly imply that the big heat problem is the cards. The cards are a big enough problem that even if you use an external recorder you need to remove the cards. EVEN if you aren't writing to the cards.
The "fix" is a plate over the processor. Go look at the LensRental blog post. The hottest area is the card slot. The cards are hot. The processor area was 15C cooler than the card slot (Something like that)
For all we know all the plate does is cool a heat sensor. The cool sensor is happily letting the camera cook itself.
