It remains to be seen who gets the last laugh! Sale numbers will be telling too.

It's a non-issue for me. I will use what it is capable of delivering (and it isn't pathetic) and be happy as can be. This issue is completely overblown and associated with folk who consistently complain instead of being thankful for the amazing multi-brand products we have access to. For me it's analogous to those who join protests so they can trash and loot. As an electrical engineer, I understand the physics of heatsinking and the challenges and compromises involved.I hope Canon does well. Actually, no... what I really hope for is that the heating issues isn't as pathetic as it is pointing out to be, and so far it really is! And if it remains that horrendous, then I hope Canon does not do well and instead learns from their mistake.

Whiners never cease. Always the same thing. 'Canon could have and should have but betrayed the customer!' How many cameras have YOU designed that can shoot this bitrate of data with weather sealing? Why are you even here? Why not out shooting your much superior Sonikon and enjoying life? Or is there an agenda behind your continued complaining?As an electrical engineer, you should know that Canon could have implemented a solution but didn't.
Pathetic? No cameras in customer hands yet and you say it is pathetic and horrendous and hope Canon learns from their mistake?
The R5 and R6 are only a mistake for those who should own a 12MP low bitrate brick shaped video camera, not a stills power house with video features and full weather sealing with excellent ergonomics and lenses.
Stop watching so many youtube influencers.

Yeah, you are right, I always think of peltiers like 100 % efficiency devices but they have less. Just today I printed a fan holder for my 600D to cool it by air flow: marginal effect through the plastic housing. So you are right too with using the peltier to get a lower temperture on the back side of the camera!The peltier is going require a bigger fan that will likely be noisier since it's generating a significant amount of heat on its own. The biggest effect of the peltier is just to drive the temperature difference beyond what you can get from the natural ambient temperature.
Uh, the fact that the heat pipes are made of copper is a marketing gimmick and has just slightly more than nothing to do with the efficiency of the heat pipe. Go study how a heat pipe works. Clue- it's an evaporation/condensation cycle.Only the simplest CPU coolers rely only on heat conduction. Most of them have heat pipes to move the heat away from the bottleneck. Like this one, where you can easily see the heat pipes that are made from copper.

It was not just a matter of making the camera bigger. Almost all serious cinema cameras have air vents and fans to circulate air through the body. This is a stills camera first and foremost. And if Canon had come out with a 5 series level of camera that claimed no weather sealing due to the camera having air vents in and out of it, the backlash against the camera would have been much bigger than if the camera just needed some breaks when using its most intensive video modes. People seem to have totally forgotten this is a stills camera first and foremost. And professional stills cameras are expected to be weather sealed. Seems like Canon just can't make people happy... Put amazing video capability into a stills camera as a bonus, and people are ready to crucify Canon because that stills camera won't perform to the level of a dedicated cinema camera.Unbelievable! If you had to make the camera a little bigger for cooling purposes, then do it. To me the size of the camera doesn't matter, what matters is I will be able to use it for more than fifteen minutes, then have to set it aside for forty minutes for it to cool down.
My first thought around this was that, maybe Canon has been clever designing the body such as they have prepared for a battery grip with a fan and a termal connection to the interior of the body, accessible through the battey chamber and thus in normal cases weather sealed. The termal connection could be either conduction (Peltier?) or convection based (air channels).
Oh no; Canon does make people happy and I'm one of them. Where Canon has trouble is in making the haters on the other side, happy - seems they do just the opposite, which is fine by me. Let the whiners be perpetually unhappy and waste their lives.It was not just a matter of making the camera bigger.

Yes, compatibility is a reason, but the way you made your first statement, it sounded like you were proposing that the copper was the medium moving the heat. Sorry if I misinterpreted your intent. Aside from working fluid compatibility, for CPU cooling, copper is useful at the evaporator end because it is easy to bond to the copper heat spreader block. At the condenser end, it is less than ideal because for all but the most far out designs, aluminum fins are used and they are not easily bondable to the copper pipes, resulting typically in a pressure contact at best. For a camera heat pipe, copper would be unacceptably heavy (likely the reason you don't see many heat pipes in cameras), which could lead to something creative like carbon fiber tubes. Also graphene may well be a more suitable thermal transport approach due to its light weight and simplicity.Copper is by far the dominant heat pipe envelope material for cooling of electronic devices. The reason is not marketing, but compatibility with the working fluid: water or methanol. See here: ACT, or Wikipedia, or whatever you prefer.
Clue: If you write your postings in a less patronizing tone, it will be easier to admit being mistaken.

Now you are the one being smug. I have opened a number of laptops that that had aluminum heat pipes. Compatibility is not an absolute, but rather a matter of lifetime. If the product lifetime is estimated to be less than the lifetime of the heat pipe, then alternate materials are sometimes used. Heat pipes are generally lighter than conduction cooling and often heavier than fans. The cooling method that gets used depends on many engineering variables.No, my friend, compatibility is the reason. I mentioned copper to let people who have never seen a heat pipe discover it in the image.
You should stick to read what people write, not try to interpret their intent.
Most people don't see heat pipes in cameras and mobile phones, because they usually don't open them.
How heavy do you think are heat pipes? How thick do you think is the envelope?
Now, you make me really curious, do you think heat pipes are used in mobile devices because, or despite their weight?
