A possible solution for R5/R6 overheating in video mode ...

[ProDude]

+1 extra cost $100 should not issue for a camera sell in $3899. Such heat sink also not a advance tech.

The thing about a heat sink is it is both a thermal mass and additional surface area. Those two things only make a difference if you use them to more efficiently transfer heat out of the system. That requires a coolant and movement: air over fins using a fan, liquid over a plate using tubes and a pump.

Your solution is extra weight, extra cost, and might buy a few extra minutes before overheating occurs because to make use of that heat sink you need a fan, power, and an air path that would compromise weather sealing.

Wrong.

A little bit more weight, less than 100$, many extra minutes with very quick recovery time and ... no compromise for weather sealing.

Copper plate

This sounds like the simplistic thinking of Wikipedia engineers who have no actual training, experience, or understanding of the implications such “simple” solutions truly incur.

LOL ... well ... yeah. Should i comment this?!

If Canon was inclined (which I'm quite sure they are NOT) they could offer a "at cost modification". if sent back to Canon service, much like the detent removal option for the custom control on the lenses, to add a nice professionally fabricated copper plate to be installed much like this guy did. Then nobody would be complaining about the overheating if they are inclined to use so much intense video. That would take the onus off of Canon. But don't think it will happen.........it most likely won't.

Someone said I wasn’t an engineer. If you had to choose which one was an engineer between two people tell me who is more likely to win: someone who suggests decisions between heat, space, safety and cost are super easy and just requires a bit of R&D ooorrrr someone who knows those are very hard compromises to make that take a very long time and cost a great deal of money?

Now, tell me, who won?

Sorry, but i had to revive this thread after this "youtube engineer" came with this brilliant and simple solution.

Add another mark to the Cripple Hammer's tally

People really need to wake up to the reality that Canon do not just do 'segmentation' (which is logical and expected), but outright deliberate crippling of their own products, to avoid "self-cannibalization". It's disgusting.

This subject is just so.....I mean, the armchair engineers are just having a field day.

In the video, he greatly increases the shooting duration with his fix while shooting IN A COOL ROOM. That's certainly an improvement and good for him. There is no real testing here, no discussion of the conditions or the parameters of his test, but even assuming a few things it is indicative of an improvement in shooting time.

https://www.lensrentals.com/blog/2020/09/investigating-the-canon-r5-heat-emission/

Now take a look at someone who has a history of being somewhat scientific about his camera business. He takes heat measurements before and after the firmware update, which at the very least removed the hard timer from the equation and allows for heat to build up a bit more to achieve longer shooting time. Of course, that's the same conclusion DIY reached.

But take a look at the external temperature from both DIY and Roger at Lensrentals.com. There is a marked increase in heat just from the change in firmware. And the card slot itself jumps up to 57C after the firmware update. That's about 135F.

No doubt using the mod to allow for the processor to continue working doesn't do much to decrease the card slot temperature, which is a consideration here. So in a cool room he gets about 39 minutes or a 43% increase in shooting time. He went to a COOLER room and even more improvement. That probably means that being outside in the sun or even in not-air conditioned places will dramatically cut shooting time, albeit better than an unmodified body.

So, with extremely little data everybody is falling all over themselves to pat themselves on the back for being smarter than Canon. Cool. I wonder if those extremely expensive CFX cards like running at high temperatures for long periods of time. I wonder if the processor or other components in the camera will have the same longevity as their original design parameters and design life. I wonder if the sensor and the IBIS mechanism react well to long running times at high temperatures. So many questions....I mean, I have so many questions. You and others obviously don't.

I'm looking forward to everyone making this mod themselves, voiding their warranties, and coming back here to tell us about their results.

This is some kind of YouTube click bait that offers no real proof a product improvement that actually works in the real world. Water coolling? Get real, how long is your hose? Is this what users want. Then go for it!! Not me. That is for sure.

The copper disk make wild claim but shows little actual proof a working camera in the the real world. Are you going to take his word for it? Where is the third party review of a modified camera prototype? It may keep the sensor cool and thereby disabling from measure the entire product including the sensor. Copper may very well cool one part leaving many other parts of the camera to cook and fail to produce good image as well as greatly shorten the product lifetime. What kind of warranty does the Youtube showman offer on his copper cure? Much more work will get done if it acutally works. He could make more money modifying R5 with copper than from YouTube. Of course he would have warranty it for a year and show it was truly cure that works at 105F outdoor summer wedding shoots.

The fan version is not weather sealed for sure.

These are not fully demonstrated or developed concepts with zero independent validation more suitable for a snake salesmans hustle than serious photographic work IMO until further proof of operation is validated by three or more others.

I mean, I get that test as a proof of concept, but it's also done with the back of the camera off and without knowing where the temperature sensors are and he's using a thermal camera that doesn't take actual temperature reading like Roger's article (as I recall anyway....and I do know that those smartphone thermal cameras typically only show a relative heat spectrum and not actual temperatures). He doesn't take a reading of the card, the card slot, tell us what card he's using, ambient temperature....you get to the science part in a second, but the whole video is simply a proof of concept and in typical human fashion those unfamiliar with good scientific and engineering practices take two small data points and extrapolate entire universes of conclusions from almost nothing.

The copper disk make wild claim but shows little actual proof a working camera in the the real world. Are you going to take his word for it? Where is the third party review of a modified camera prototype?

One big part of product development is testing. That's one reason some seemingly intuitively obvious things aren't done: at some point you have to stop testing and make a product you can sell. Seemingly counter-intuitive solutions, like two partial thermal pads rather than thermal paste, may actually be there very deliberately because of the results from extended testing.

It may keep the sensor cool and thereby disabling from measure the entire product including the sensor.

Exactly.

Copper may very well cool one part leaving many other parts of the camera to cook and fail to produce good image as well as greatly shorten the product lifetime.

Exactly. And these are just our guesses. Imagine what the actual engineers knew and had to contend with. The list of unknown-unknowns (versus our guessed or assumed-unknowns) could be as long as your arm.

What kind of warranty does the Youtube showman offer on his copper cure? Much more work will get done if it acutally works. He could make more money modifying R5 with copper than from YouTube.

Well, the fan version that just blows on the back of the camera is. But then how hot does the back of your camera get?

These are not fully demonstrated or developed concepts with zero independent validation more suitable for a snake salesmans hustle than serious photographic work IMO until further proof of operation is validated by three or more others.

I can't wait for folks to modify their extremely expensive cameras and do some real world testing that has zero consequences for me....neither my camera nor my feelings will be hurt should they decide to burn their money. And if it does work, then good for them and it still has no effect on my life.

This is some kind of YouTube click bait that offers no real proof a product improvement that actually works in the real world.

I have watched many of this guy's videos over a number of years. He is quite talented, creative and has some serious fabrication skills.

Water coolling? Get real, how long is your hose? Is this what users want. Then go for it!! Not me. That is for sure.

I don't see why people think he was offering the water cooling as a realistic solution. He clearly stated that the reason he even did the water cooling was to determine whether it was the processor causing the bulk of the overheating problems. His water cooling test worked beautifully for this purpose.

The copper disk make wild claim but shows little actual proof a working camera in the the real world. Are you going to take his word for it?

He tested his results and was transparent in his methods. I think is is obvious that any fix radiating heat from the camera body into the environment would be more effective as the ambient temperatures dropped and vise versa. Before trashing the guy's reputation watch his other videos. You will get a better idea of his skill level.

Where is the third party review of a modified camera prototype?

He is a YouTuber that is DIY oriented. He is not going to market this fix. He was very transparent in is theory, execution and analysis. He is presenting his results for public consumption. I expect there will be more than one company looking into what he has done and seeing if it is a viable solution to bring to market.

It may keep the sensor cool and thereby disabling from measure the entire product including the sensor. Copper may very well cool one part leaving many other parts of the camera to cook and fail to produce good image as well as greatly shorten the product lifetime. What kind of warranty does the Youtube showman offer on his copper cure?

He says at the beginning to try this at your own risk. A warranty? He isn't selling anything.

Much more work will get done if it acutally works. He could make more money modifying R5 with copper than from YouTube. Of course he would have warranty it for a year and show it was truly cure that works at 105F outdoor summer wedding shoots.

This is a prototype. This means it should have further R&D applied before being sold to the public. I think it is safe to assume that anyone applying this type of fix will knowingly void their camera's warranty. Any company selling a variation of this fix will make it clear that it will void the warranty. IMO, professional videographers will not hesitate to apply this to their R5 if it allows them to use the camera more effectively and efficiently. Time is money. Waiting on a camera to cool down for far longer time periods that shooting video with it is not a money maker.

The fan version is not weather sealed for sure.

It could be to some extent. He is just providing proof of concept. He succeeded. Also, not everyone needs weather sealing for the type of work they do.

These are not fully demonstrated or developed concepts with zero independent validation more suitable for a snake salesmans hustle than serious photographic work IMO until further proof of operation is validated by three or more others.

This guy is not a head of a multi million dollar corporation providing finished products for use. He is a talented INDIVIDUAL making interesting videos on a number of topics. He decided to see if he could come up with a probable solution to reduce the overheating issue in the R5 he uses to record videos. He succeeded for more than even he expected. He might have decided to tackle this problem for his own benefit first and foremost.

Then nobody would be complaining about the overheating if they are inclined to use so much intense video. That would take the onus off of Canon. But don't think it will happen........it most likely won't.

Canon's problem doing this now is it would prove they lied to us previously about not being able to conquer the overheating problem better than they initially provided. One overlooked result of this YouTuber's work is he proved the first firmware was basing its shutdown on time passing and not elevated temperatures. The first firmware used with the water cooling test shut the camera down in about the same amount of time as an unmodified R5. This was even with the thermal imaging showing the processor was not overheating. Installing the updated firmware with the water cooling active allowed unlimited 8k recording time. This is damning proof Canon gimped the 8k recording time of the camera with firmware when it was first released and not on actual temperature readings.

Also, I think if Canon provided this fix now they could very likely see a class action lawsuit for misleading people on this overheating issue when the camera was first released. It wouldn't be hard to prove the first firmware was timer based and not temperature based. In fact, IMO, this YouTuber has already proved it.

Sigma FP (ultra lightweight FF) also weather sealed and able solve overheat issue.

Gaming phone (e.g. Razer Phone II) can use vapor chamber to solve overheat.

Either of them doing bit-rates or processing similar to R5? There is no overheating issue at lower bit rates even on R5

 

[NickZ2016]

If you can afford the cards for 8K raw continuous shooting two or three R5 shouldn't be an issue.

If you want to really whine about segmentation complain about the tiny little batteries. The lack of serous ports. The lack of a stock top handle. The lack of ND filters. All those things are more likely to force people up to a C class camera.

The R5 doesn't overheat in all modes. Do both Sigma FP and Z Cam E2 do the modes that we are comparing them with R5 for? 8k, Oversampled / HQ 4k, 4k 60?

 

[whumber]

IBIS keeps the sensor floating, isolating it from the body. There is no efficient way to conduct heat from the sensor.

The sensor is not floating in air, it's sitting on a set of bearings which do conduct heat, albeit less efficiently.

Fan or heat sink can keep the outside of the body cool. But the sensor is still tens of degrees hotter than the body.

The sensor is almost never the limiting factor though, it's the image processor that generates the most heat by a large margin. Notice that the guy who did the water cooling and installed the copper plate to get unlimited 8K recording only made modifications to the image processor, he didn't have to make any changes to the thermal pathway for the image sensor.

They're both using a combination of CPUs (FPUs are just a subcomponent of CPUs) and ASICs. If you only had an ASIC designed for processing video you'd have a really tough time actually running the camera and there's no way Canon is getting the kind of video processing capability they have with just a general purpose CPU.

LOL Unfortunately, you’re talking to people that think shooting 8K will make them into the next Alfred Hitchcock or Martin Scorsese. The needs of professional videographers are simply beyond their understanding because the only thing that matters is 4K....no 8K....no 16K.....64K!!!!!!

These spurious arguments crumble to the ground when any kind of logic or context is applied rationally as you have done. Somewhere around here an argument much like the rampant conspiracy theories we have to deal with in this modern internet age was put forth saying if Canon offered a similar copper heat sink mod they’d probably face a class action lawsuit for their fraudulent marketing of this camera. So people are not only engineers and market analysts but lawyers too! Never mind Canon has offered minor upgrades in the past to improve performance despite absolute truthfulness about the product. And also never mind Canon was truthful about the R5’s abilities before it was released. When was the last time Coke was sued for claiming that drinking their beverage will make you beautiful on a beach with other beautiful people running around playing volleyball? Are we not smart enough consumers to know that 30 second commercials or press releases don’t cover all the bases? Marketing tends to paint exaggerated pictures of products and only in egregious cases does anyone sue and win.

These arguments are naive bordering on juvenile.
