Canon EOS R5 / R6 overheating timers, workarounds, and Magic Lantern

[amanieux]

in the r5 watercooling video from diyperk, his internal temperature measurement showed a 83 degree temperature on the cpu board, if you keep on recording  without cooling, won't the image sensor get warmer and start to show up more image noise as heat goes up ?

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!

Per vedere se esiste una soluzione più economica rispetto alla scheda CFexpress di tipo B per Canon EOS R5, ho acquistato il convertitore CFexpress su SSD da Zitay.
E un'unità SSD Samsung 980 Pro PCIe 4.0 NVMe M.2 separata da 2 TB.

In totale, è ancora molto più economica, ad esempio, di una scheda CFexpress Sony Tough 512 GB (per me 6,2 volte in termini di capacità di archiviazione).

Ora posso riprendere filmati RAW 8K fino al limite di 29:59 minuti senza ricevere un avviso di surriscaldamento!

Can you show me how you close the card slot with this adapter? Can you post a picture? thank you.

[HansD]

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

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?

I have this Delkin Devices 2TB CFexpress POWER Memory Card DCFX1-2TB B&H (bhphotovideo.com)

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. In my 8 months R5 only shooting 8k raw and 4k 120 (the only two modes that I use) it never overheated once. I do many short takes up to 5min....

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

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

[gt3rs]

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.

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.

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.

This is so strange.

It can record 8K to much slower cooler SD cards and still overheat just as quick, so the media isn't the primary cause of the overheating is it?

Or maybe it was after all?

È così strano.

Può registrare 8K su schede SD molto più lente e più fredde e surriscaldarsi ugualmente velocemente, quindi il supporto non è la causa principale del surriscaldamento, vero?

O forse lo era dopotutto?

Bought and tested with my r5 with latest firmware ... heats the same. I don't understand the user above how he made unlimited raw recordings! This is wrong information. I send it back immediately ... I already have 2 cf express 512 the chamber heats up as with the cf express. If you buy it to avoid overheating forget it, it heats the same.

[Andrew Reid]

Yeah seems strange to me. Approach with caution. It's a janky ass solution anyway.

[andrgl]

Are there any overheating tests yet with the  new Atomos Ninja V+?

Also curious if the R5 and V+ will get 120FPS 4K ProRes RAW at some point.

Would make this camera a very compelling purchase if it extends the record time and provides another codec for high speed.

 

[Andrew Reid]

HDMI was never an issue was it?

I'm a bit hazy on the details now as I sold my EOS R5 and won't be buying another Canon for a while.

R3 looks tempting though.

It is such a false info…. media is a contributor to the heat and having the door open will have some minimal cooling effect but is not the main issue and solution seems really fragile.
