The EOS R5, one of the latest additions to Canon’s full-frame mirrorless camera line, offers class-leading autofocus with high-resolution and high frame rate video recording options using the maximum width of the full-frame sensor at high bit rates. Inevitably, this combination of features has the potential to generate some significant heat, which will limit recording time.

An “overheat control” function to reduce heat generation when the camera is in standby
In regard to the installation of a fan: The decision not to install a fan within the body was made in order to maintain the EOS R5’s compact size, lightweight construction, and weather resistance.
Before recording starts, the EOS R5 and EOS R6 display an estimate of the recordable time based on the current camera temperature and the set recording mode.
Canon has published and included below the approximate recording and estimated recovery times for 23°C / 73°F environments and ensures that the camera will warn users when it is getting too hot. Additionally, tips to reduce overheating as well as recovering time are listed below.
How to reduce heat build-up in the Canon EOS R5
Set Overheat Control function to “ON” (default). When the overheat control function is enabled, the movie size and frame rate are automatically changed while the camera is in standby mode to suppress the rise of the internal temperature.
Between recordings, it is recommended to turn off the camera and position the camera out of direct sunlight. You can also use an external fan to dissipate heat.
Recovery time for the EOS R5:
Estimated camera recovery times are indicated below. The time until full record time is available will vary with ambient temperature, continued camera operation, and the selected shooting resolution.
Canon EOS R6 Statement
Like the EOS R5, the EOS R6 offers powerful movie recording and stills capabilities within a compact body design. At the highest frame rates and resolutions, heat is inevitably generated. We believe the EOS R6 offers the best in class performance, especially for enthusiast photographers and video content creators.
The EOS R6 can record up to the 29 minutes 59-second recording limit in the 5.1K oversampled 4K 60p mode at (23°C / 73°F) before encountering any heat-related issues within the camera and up to 40 minutes of 4K at 30p.
Canon’s animal AF featured on the new Canon EOS R5 is said to work very well. Here are some real world examples that seem to confirm it.
Courtesy of Marcus C, the videos below show how well animal AF on the Canon EOS R5 works. The tests were made with a pre-production unit of the EOS R5.

Canon EOS R5 and EOS R6 preorders appear to be over the roof, despite the idiotic “cripple hammer” and “overheating issue” crap.
Canon Japan released a statement where they recognize that EOS R5, EOS R6 and battery grip BG-R10 preorders exceed the company’s forecast and that shipping might get delayed due to short supply.
Regarding the following products announced on July 9, 2020, if you order more than expected, it may take time to deliver the products.

We apologize for the inconvenience, and thank you for your understanding.
This was expected. Already months ago it was rumored that the global COVID-19 pandemic would affect supply chains and hence manufacturing of the R5 and R6.
