I bought a Canon EOS R5 - potential overheating solutions In: Cameras Posted August 12, 2020 There's no reason why Canon would market the camera at pros, with the intention of disappointing them. You make a customer spend thousands on a camera that he then realizes is useless for his task. Do you think he'll say... oh, in that case I'll buy an even more expensive camera from this brand? I think most people will boycott the company that has fooled them. As for 47 degrees or whatever being perfectly fine, as CPUs can hit 95 °C... erm, no? There are chips which will have no issues with that, there are chips that do. Also, you have no idea at which point of the camera the temperature is taken. The sensor could be so far away that if at that place 47 °C is reached, parts of the chip are boiling. Also, pumping out the heat to the casing/accepting high temperatures (say 95 °C) is a bad idea that no manufacturer in the right mind would accept on a mobile device. There'd be lawsuits. It boils (no pun intended) down to this: If the CPU heats up to nearly 100 °C, and the heat is immediately transfered to the casing, it is transfered to contact points. Best case scenario, the screen is used to dissipate heat, which damages the screen. Worst case: The photographers/videographers hands are burnt. I have a Samsung tablet where the heat output when not used in the keyboard casing is reduced. The CPU is throttled to roughly 1.1 GHz, vs 2+ GHz. Why? If the tablet is not in the casing, it is probably in the hands of the user. Allowing it to hit 90 °C would be BAD. Another example is the MacBook Pro, Retina vs Touchbar version. The Retina is better at dissipating heat, however, hot air was blown over the screen, leading to discoloration on some devices. So Apple has fixed it by only piping heat to the rear, downwards. Unfortunately depending on how you use it this blocks the cooling solution. In any case, notebook manufacturers try to keep touch points cool enough, even if letting them get hotter it would mean better performance. But how about a camera? Which parts are not considered touchpoints? Would you be willing to accept skin burns? Really, it seems like Canon should have been using heatpipes and a small fan. However that'd be bad for sealing, the camera would be bigger, etc. Or, more likely, Canon shouldn't offer these features internally in the first place, even if the camera would be capable enough.
