The Canon EOS R5, despite receiving firmware update to help reduce the chances of it happening, has a thing for overheating when shooting video. Every single piece of (admittedly, circumstantial) evidence points to it being a timer that’s hard-coded into the camera and not really based on the temperature inside the camera at all. Or is it?
Matt at DIYPerks decided to have a go at liquid cooling his shiny new $3,900 Canon EOS R5. And after doing tests using the original firmware, he saw the results we all expected. The camera shut down right at the time limit, despite being cooled pretty much to the ambient room temperature. When he installed the v1.1 firmware update, though, everything changed.
