Watercooling a Canon R5 to enable unlimited 8K recording
"Matt also believes that Canon could have designed the camera to dump the heat toward the bottom of the camera and then sold a separate base attachment for videographers that provides vastly extended recording times."Seriously, this.  I wonder if they could make the area around threaded screw on the bottom for attaching to tripods a heat spreader.  These are usually made out of metal already, and have to be structurally sound for the camera to be attached there.  If the attached base was a block of aluminum or copper, it could probably suck the heat out of there.
