5K is just the R5 crop, not a Ninja V+ feature.

Interesting, but the 8K test is very doubtful.
At this moment the Canon EOS R5 is not capable of outputting 8K through HDMI.
Till the firmware update for the Ninja V+ it is still 4K!

Unlimited 4KHQ and 8K recording - No mods needed!

Just know where the heat building up is coming from.

So how does that work? Doesn't the door have an 'open' detector/switch? You have to block it?

The Zitay converter is supplied with rubber (red) stops. They say 5, I got eleven of them!
See (iPhone) picture below.

Nice, but wish there was a way to not have to cut into the door and lose warranty, weather sealing and resale value.

That is why I didn't cut into the door so I can always use CFexpress cards if needed and the camera keeps its resale value.

Looks like something ready to break, big chance to lose data....not even sure how stable is when the battery runs low and so on. 

Imo is the wrong saving (if any)  but if it works for you.
 

Have a nice day.

I may be wrong but I believe the door open has more to do with not overheating that the external storage. The thermal control is there to prevent damage is like a rev limiter in a car it will not have any consequences.

This assumption is also incorrect.
Users with a closed battery cover get the same results as me.

Not sure it is really worth, risking stuff entering the camera, breaking the door, breaking the cable etc.. 

A delikin 2 TB CFexpress that sometime is on sale for 800$ is a better investment.

I have not found the Delikin brand. You probably mean Delkin?
Never heard of it, can't buy it here either.
The build quality of the Zitay converter is excellent and I would be surprised if this flat cable breaks or comes loose.
But yes, not everyone is careful with their camera gear.
Any CFexpress you use with 8K RAW in the Canon EOS R5 will lead to overheating (with firmware 1.3.1 22 minutes!)
And what will the long-term consequences of this be?

Some people just make a small opening in the battery lid.
I just use the supplied rubber stops.

To see if there is a cheaper solution than the CFexpress card type B for the Canon EOS R5, I bought the CFexpress To SSD Converter from Zitay.
And a separate 2TB Samsung 980 Pro PCIe 4.0 NVMe M.2 SSD drive.

In total, it is still much cheaper then, for example, a Sony Tough 512 GB CFexpress card (For me 6.2 times in terms of storage capacity).

Now I can shoot 8K RAW footage up to the time limit of 29:59 minutes without getting an overheating warning!

Lensrentals Investigating the Canon R5 Heat Emission

https://wordpress.lensrentals.com/blog/2020/09/investigating-the-canon-r5-heat-emission/

Canon's development department has shown what is possible in a small body. Now the marketing department is intervening. They will spread the technique over various models. Any model with a little more options. C70, C170, C270 etc ???

The rumor of the C70 is just as strange as the picture, just look at the difference in lens and body blur. Fake?

Ok, so only way is to open the camera and unplug the board with the power storage.
Another way would maybe to do a "firmware update when the new firmware will be present, right after overheating.

Testing would be to turn on the camera until it reach the fake overheating logo.
remove the battery 
Unplug the board with the power (I can see a red/black cable on the bottom left) 
Wait 10 second,
Plug it back and see if overheating is still present.
This is only to prove that these warning are fake.
I guess there are some overheating sensor in case. But on the test done here, it's the "timer" overheat that kick-in first.
This is so wrong.

Maybe the whiz kids at Magic Lantern can reset the counters. But it is very quiet there as far as the R5 is concerned!

I am retired now but have experience over many years as an electronic design engineer.

If there are 'timers' employed in the design then it is likely they would 'reset' to a zero or starting count state when the power is removed and then returned to  electronics. This would occur when the battery is removed. for a short period..

However if Canon was clever they could continuously write the count value of the timer(s) to a non-volatile memory  and when the power is resumed ( after battery removal ) the values of the count stored in the non-volatile memory could be returned to the timer(s). To do this there would have to be some non-volatile memory in the camera.

 

Canon has been doing that for a while! How else can they keep track of the shutter count without an extra battery inside?

You may want to check, but there is a button cell to keep the camera time
https://www.ifixit.com/Guide/Canon+EOS+5D+Mark+II+Clock+Battery+Replacement/31531
Look more for something like this to reset time.

If this reset the recovery time or recording time, it's the 100% proof that there is no valid temperature reading, but time based only

This is for 5D, but I guess 5R have something similar
 

 

The EOS R5 manual indicates that there is no separate battery for date and time storage. Probably just flash memory.

I may have overlooked it, but I haven't seen a message that the Canon EOS R5 gets very hot on the outside too.
Armando Ferreira says in his video 'The Canon EOS R5 IS NOT AN 8K CAMERA!': When the camera (R5) says it is overheated, I touch the camera, it is pretty much cool to the touch!
Does this not indicate badly calibrated heat sensors or an incorrect reading by the firmware? Or a combination of both?
