Canon R5 Mark II camera overheating test videos have now surfaced on the web from those who have purchased this camera with their own money and are now testing it out. So, we have to believe that, specifically for those who have purchased this camera, they are providing rock-solid and pure information, not influenced by any brand. These are not brand influencers; they are real consumers out there.
Now, after the tests, what they have found is that the overheating chart provided by the Digital Photography Review team, which is also similar to what we can see on Canon’s official website, is correct. If you are shooting videos at a temperature of 23 degrees Celsius.
All figures are measured with the camera in an unused state, with both the camera and environment at 23°C (73°F). Use in warmer conditions or direct sunshine will shorten all of these times.

The big issue is that not everyone lives in cooler regions; many professional video camera users are located near the equator. During the summer season, temperatures can easily reach 40-45 degrees Celsius [40 degrees Celsius is equal to 104 degrees Fahrenheit]. We have to wait for more test results from those regions to see how this camera performs under stressful environmental conditions.
On the bright side, we do have a cooling grip from Canon that cools the camera down more quickly—about 2x faster than without using that particular grip. It also extends the recording time, which will surely help those living near the equator or in areas with harsher summer conditions.

I could not say it’s just another R5 simply because Canon R5 works very well after 1.6.0 firmware update. No more overheating shut downs.
To make the test even more comprehensive, it would be interesting to see how the camera performs in extreme conditions, such as in 40+ degree Celsius environments, both with and without the cooling fan. This additional data could provide a complete picture of the camera’s reliability under stress.
@Marcos Yes, it’s true that the Canon R5 performs significantly better in terms of overheating after the 1.6.0 firmware update. I am a user of the Canon R5 and I have noticed many updates here are they
Since the release, I’ve been testing how the new option affects overheating. It seems to be a big improvement. So I thought I’d share my results.
All tests were shooting the TV, so the camera had some motion to process. The room was about 19-20 °C (66-68 °F). Obviously the 30 minute record time limit (7.5 minutes in 120 FPS) kicked in, so I just pressed record again each time the camera stopped, until it actually overheated and shut down — or I got fed up and went to bed.
In all cases, once the camera shut down, I stopped the test. Of course you can let it rest a bit and get more time out of it, but how much time depends on how long you let it cool. With infinitely many options, I couldn’t be bothered testing this. The camera was allowed to get stone cold between these tests.
Auto power off temp = Standard
4k HQ 23.98 warning @ 31m 02s, shutdown @ 40m 18s
8k IPB 23.98 warning @ 25m 50s, shutdown @ 33m 57s
4k LQ 59.94 warning @ 1h 11m, shutdown @ 1h 41m
4k LQ 120 warning @ 14m 45s, shutdown @ 19m 53s
Auto power off temp = High
4k HQ 23.98 ran for 3 hours, no warning or shutdown, gave up
8k IPB 23.98 ran for 4 hours plus, white warning after an hour or so, red warning intermittent, no shutdown
4k LQ 59.94 ran for 3 hours, no warning or shutdown, gave up
4k LQ 120 white warning @ 22m 50s, red warning @ 29m 45s, shutdown @ 35m 54s
In the cases where the camera ran for 3 hours or more, it just didn’t seem to be getting hotter, so I couldn’t see much point in continuing. The camera was pretty warm after these tests, but not crazy; though the memory card was too hot to hold. It cooled down pretty fast, though.
For a mirrorless camera without active cooling, this looks about as good I would expect.
Obviously I can’t guarantee that you’ll get these run times. Individual variations between cameras, different environments etc., will all have an effect. In particular in the 8k test, the warnings were showing intermittently after the first hour or so, so the camera was clearly close to the edge.
Please bear in mind that in “High”, the camera can get hot, so watch out for low-temperature burns if you’re holding the camera for a while.
…And Stella, I live in Central Brazil, where temperatures are usually around 32 Celsius during the day, almost every day. No problems of overheating since I updated it.
@Marcos, that’s great to hear! It’s really reassuring to know that the update is holding up well even in hotter climates like Central Brazil, especially for those of us who shoot in cooler environments and might not push the camera to its thermal limits as you do. It’s amazing how much of a difference this firmware update has made. Thanks for sharing your insights—it helps paint a more complete picture of the R5’s capabilities across different conditions!
Great article! I’m curious—does the stacked CMOS sensor in the R5 Mark II affect the image quality compared to the original R5? If image quality is my top priority, would it be better to stick with the original R5, or does the new sensor offer any noticeable improvements? Also, does the image quality at higher ISO degrade due to the faster readout speed?
