R6 (and maybe R5) overheating issue

umphotography wrote in post #19108280
I think everyone should really look at this tear down of the camera and then make decisions as to should they buy the R5 or R6

This is not good

Really shows that canon has cut a lot of corners in the build process and that a lot of the overheating may be due to firmware

The term Planned obsolescence comes to mind for me

Really obvious by this tear down that the camera could and should have been built a lot better than i was

I think there will be a recall on this camera and the hit to canons reputation is going to be huge

read here. Lots of pics. really sad commentary about these bodies- The story on his site with physical evidence shows that Canon crippled these cameras either deliberately or through incompetence. Canon is *not* incompetent. So that leaves only one other possibility. If true, they have bigger problems on their hands.

I guss you haven't caught the entire discussion surrounding this yet.

Essentially the guy has a beef with Canon. You may want to take this into account.

I am sure there is a reason why Canon shields the memory DRAMs, but not the processor.

From all accounts i have seen so far, the problem actually arises from the memory cards, as removing them solves the issue(s).

Kind regards, Wim

Can you provide a link to that information?

If you scroll down in the comments, you'll find a comment from Gerald Undone as well, where he mentions that if that is the case, he can actually recommend the camera too for video.

Basically, the combination of processing HQ video modes, 8K and 4K 120, writing to the meory cards, overheats the memory cards, and the camera as a result.

There actually is a high quality 4K mode that does not overheat, which is the 4K oversample 5.6K crop mode, effectively a Super 35 mode.

Now that I went searching, I found this...https://petapixel.com …r5-overheating-over-hdmi/

But I also note a key statement

...simply removing the memory cards from the Canon EOS R5 basically “fixes” the camera’s overhearing problems when shooting to an external recorder.

This was established a week ago so not sure why the overheating is still so heavily debated. If you’re a pro videographer simply use an external recorder like the Atomos Ninja V or some such device. Problem solved.

No it isn't proven that it is the cards. Running a clean HDMI signal out doesn't tax the system at all compared to actually processing frame by frame and creating the movie file. Any system that is heavily ladened with doing video processing gets very hot.

There are two things at play when you record to card, the memory, processing power for the video file, and file I/O and then the card itself. The card may be contributing a bit, but is likely not the main culprit.

The only way to prove this is to manufacture some sort of CF express cable that plugs into the card slot and extends outside the camera to a card reader/writer.

3 Points to Ponder:

1) Basically with an external recorder, the camera simply becomes a monitor and not a processing center, therefore the main board doesn't get as hot.
2) Also just shooting stills heats up the camera as well (using SD card slot), to the point that you barely have any video time left when you decide to flip to it.
3) The R6 also heats up and takes longer to cool down, and doesn't have CF express cards.

Again as has been stated in many other threads, the only useful thing from that link is the tear down pictures. The rest of the "experiment" was terrible, and when the guy from EOSHD already has his conclusion drawn and wants to sensationalize the issue, he will exhibit "procedural bias" when coming up with his tests. That is a prime example of such a thing.

The only way to put this to rest is to actually tear down the camera, throw in a few thermistors at key locations in the camera, run the leads out through the battery or card slots, close it all up, turn it and run it through its paces. Record each location's temperature at set times for set conditions (just on, on and shoot bursts, on and shoot video, etc), and graph the results. Also monitor everything during cooldown... That will provide a more concise picture of what is going on. In fact this is the only real way to determine what is going on.

Places to put a thermistor:
- thermal pasted to Digic chip
- thermal pasted to each ram chip
- thermal pasted to CF Express carrier
- thermal pasted to rear LCD controller

That gives you 7 data points, and taken every 30 sec while the camera is taken through its paces would show a very good picture of whether this is a hardware design issue, or if truly Canon has thrown in soft limits and times into the camera to limit its usage.

Then guy was actually doing 4K HQ and 4K 120p to the external recorder. IMO that proves enough, as the processing is still done through the camera's processor.

As mentioned, there also is a 4K crop mode, Super 35 effectively, which downsamples from a 5.6K mode. That does not overheat either. Check Alex Barrera on this.

Kind regards, Wim

Those video modes are done by the recorder. The recorder isn't like an external USB drive and the camera feeds it a file, it is pulling an HDMI signal and doing all the video options for you. The camera just sends a clean HDMI signal out just like it sends what the sensor sees to the LCD or EVF.

If you tell the recorder to do 4K 120, it is taking 120 separate snapshots per second from the HDMI feed and creating the file, doing all the work the camera would have to do if the camera was making video files onto the card.

Basically the Atomos Ninja is an eavesdropper and recording what it sees and hears, while the camera does nothing more than project the video and audio live streaming out the HDMI port. The only real work the camera has to do is to determine what resolution to output (auto to match the device hooked to the camera or locked in at 1080).

So on FredMiranda, we keep getting into the discussions on how just outputting an HDMI signal so an external recorder can do whatever snapshot and save to a file process it wants to do, and how that can keep the R5/6 cooler.

I brought up the fact that the M6II can do 4K30, and is 33Mpx and doesn't have any issues with any kind of overheating that I am aware of. 33Mpx vs 45Mpx isn't that big a deal, and is more than the R6, but no issues.

I made this observation and have these questions:

- The M6II is a much smaller package, does 4K30 video and is 33Mpx, which is within spitting distance of the R5.
- Both the R5 and R6 overheat, yet the M6II has no issues, despite it being a smaller body.
- The M6II doesn't have Eye AF and Deep Learning configurations to dig through, both the R5 and R6 do.

Has anyone tried video and stills with single point AF and turn off all the Eye AF functions/iTR type settings to see if there is any impact to temps and times? The big thing people are excited by and are using with these 2 cameras is eye AF, and this would be active whether stills or video. What if one could turn off all the deep learning algorithms and stick with traditional phase/contrast detect AF? Perhaps some of the overheating on the R5/6 is due to needing a Digic X and all those ram chips to chug through the deep learning dump Canon put on the camera to give it its wonderful eye AF?

No, it is the CF Express card, even if you still do not want to believe it. Th eM6 II has an SD card, up to UHS II, the R5 and R6 an SD card plus an CF Express card. Taking it out solves the problem for the high intensity video modes.

Kind regards, Wim

The problem with that theory is that there’s no CF Express card in the R6; it only takes two (UHS II) SD cards.

Snapsy at Fred Miranda who created the Dot Tune MFA method was having a conversation with Andrew Reid at EOSHD. Reid kept insulting him, snapsy kept to the point and got banned.

Im not reading as much overheat issue with the R6 unless its shooting video. Dont find the complaint with stills

Do you have anything about the R6 and heat warn lights shooting stills ?
