Canon R5 Cooling Problem Fixed

The few people who would buy a hybrid over a cine camera have far more issues to look at.

No built in ND filters. No XLR ports. No SDI. No video style batteries.

Why are people excited about the C70? It's just a plain 4K super35 camera. But it costs more than the R5. The features it brings are more important for the Cine market than 8K

This just smacks of Canon again gimping a camera to protect their Cinema line. The thing that really irritates me about this situation is Canon coming out and saying they had heat issues and this is why the 8k and HQ 4k is so limited. In reality it appears they either created the heating issue or intentionally decided not to handle it with a simple, cheap effective fix. Instead, they released a firmware update hoping it was enough to tamp down the complaints. If this fix gets refined, applied to a lot of cameras and is highly effective, I predict Canon is going to take a serious hit to their integrity over their deceptive actions and comments.
I just can't believe in this day and age that they could not have managed the heat better. As I pointed out earlier, there are graphite sheets today that are better than copper. It does smack of Canon protecting their camera line.

They still would need to get the heat dissipated someplace and having today's plastic covers works against dissipating heat. I like the idea of passing the heat to the tripod screw. They could have made a larger surface in that area to passing heat to an optional external heat sink and thus not have compromised the sealing (I would be anti-fan and holes in a camera). My point is that it would not have taken that much of an effort to make it much better.
 
Not for the faint of heart tho.

That's a nice solution. But I wonder how much heat is now dissipated through the back plastic panel and how that heat would affect the LCD screen if it remained shut on the back of the camera instead of extended out?
 
If Canon made ANY mistake outright, it would no doubt have been regarding the way they marketed the R6-R5. They leaned far to much on the 8K thing to where people were under the "mistaken" impression they could use 8K with careless abandon just as they'd used 1080P before. Ironically after the fact, Canon showed documentation regarding the LIMITATIONS of the length of shooting time before it would shut down. it's not like Canon kept this a secret. Just that they didn't show their marketing information ahead of time with a * to alert those who were planning on buying it to run at weddings for an hour and such would not be ideal. Better to get a R5 or R6 and one of their C200 or C300's as a pair for such an event.

Personally as an example, I prefer to use some Youtube folks as an example, that hike in parks and such taking what appears to be a 15 second shot and blend those length of shots into a continuous move in post. It's sooooo much more enjoyable to watch then someone just hiking for a half hour up a path watching the entire thing endlessly. Same thing at a wedding. Smart one's take short takes and blend them. That won't heat up a camera so badly as trying to do long runs. Oh well. Can't tell them what to do I guess.

Perfect example is what Panasonic did releasing their truly specialized S1H model. It was an S1 on video steroids all the way including built in fan and more feature sets specified towards those who need the higher end video capabilities. Now it's the preferred camera for video on Dpreview's video's. Smart of Panasonic to do so. It doesn't mean the S1 or S1R don't do great video, but are not geared towards the MOST serious video users. Canon isn't working toward that model and I don't chastise them for it.
 
If this guy can fabricate a part by hand and fit it to the camera and it works, then Canon could have EASILY solved the overheating problem of the R5.
Mike, I know it seems logical to draw that conclusion, but that’s simply not true. He added cost and weight to the R5, both in materials and labor. He also moved the heat to an area accessible to the user which means their skin can come into contact with a very uncomfortable temperature. And while the heat dissipation is improved, components are also running for a length of time that is untested by the manufacturer (or tested and known to cause premature failures).

So, there’s premature claims of failures or overheating that will occur when you create a hot spot. There are all sorts of power issues that come from running hot electronics for extended periods of time. There could be longevity issues with computers.

PROPERLY cooled components designed for extended duty cycles require more research, more materials, more testing.....
All it would take is to design a heat tube to route heat to an external surface of the camera. This is done in smartphones as an afterthought.
Which produce far less heat.
It looks to me like the lack of applying effective heat management was intentional because the engineering and cost to add this type of cooling system would be minimal.
You don’t know that nor do you know the design considerations at play. Also, cost and profits matter.
Especially if a guy with hand tools and limited resources can do it.
What testing did he do? How will people react to a 50 or 60 C hot spot? How will the electronics react to extended exposure to heat while simultaneously under load?
It is Canon's prerogative to limit capabilities of a camera if they choose. What irks me is how this camera's video capability was up front and center in the marketing effort. They used its video prowess to entice people to buy the R5. The R5 is a very good camera but $10 worth of parts would have let it live up to its billing.
You’ve fallen into a trap by making that assumption. And firmware changes made the R5 much more usable.

You’re just oversimplifying the issue and then extrapolating far reaching conclusions and then assuming you’re not only correct but in possession of all the data.
 
The problem that remains is the other videos on external recording clearly imply that the big heat problem is the cards. The cards are a big enough problem that even if you use an external recorder you need to remove the cards. EVEN if you aren't writing to the cards.

The "fix" is a plate over the processor. Go look at the LensRental blog post. The hottest area is the card slot. The cards are hot. The processor area was 15C cooler than the card slot (Something like that)

For all we know all the plate does is cool a heat sensor. The cool sensor is happily letting the camera cook itself.
If the results of the fix in the video is accurate then the card is not the main issue with overheating. He ran the camera for hours recording 8k video and it didn't overheat to the point of shutting down. I am not doubting the CF cards get hot but it appears it is not the reason the camera shuts down. Otherwise, Canon would have also monitored the CF temperature and factored it into the shutdown algorithm. It appears they did not.

This is a potential fix that is just put out. Time will tell if this is a legitimate fix for the overheating issues. If some variant of this approach is more widely adopted because it works, then my statements are validated. Also, this fix appears to have worked under the firmware's heat control measures being applied so I tend to lean toward the application of this fix not affecting the long term reliability of the camera. If fact, it will probably increase its long term viability by keeping the heat spikes to a lower level.
All it would take is to design a heat tube to route heat to an external surface of the camera. This is done in smartphones as an afterthought.

Smartphones generate a lot of heat and it is done in a much smaller, tighter space.
It looks to me like the lack of applying effective heat management was intentional because the engineering and cost to add this type of cooling system would be minimal.
You don’t know that nor do you know the design considerations at play. Also, cost and profits matter.
I can infer it with a decent amount of surety because a guy actually did it for less than $1 in parts and installed it with virtually no interference with existing components. Heat tubes are manufactured by the billions and cost very little per unit to produce. A cost easily absorbed into a $4k camera body. As for fitting a heat tube into the body, it would be simple to do as it is done in smart phones which have far worse space constraints.
Especially if a guy with hand tools and limited resources can do it.
What testing did he do? How will people react to a 50 or 60 C hot spot? How will the electronics react to extended exposure to heat while simultaneously under load?
He ran the camera with the rear plate off to get direct temperature readings from the PCB over the processor and memory. The lowered temperatures after the fix as applied allowed longer recording (and only five minutes wait periods after overheating) compared to stock conditions. Also, it is better for components to see smaller temperature fluctuations which is happening after the fix is installed.

You’ve fallen into a trap by making that assumption. And firmware changes made the R5 much more usable.
The guy actually tested the results with both firmwares installed after the fix was applied. The updated firmware resulted in much longer record times than the original firmware with the fix installed. This is empirical data so there isn't a lot of assumption being made on the results of this addition to the camera. The camera recorded 43% longer with the fix and updated firmware than it did stock with the updated firmware. When he tested the camera in a cooler room it ran continuously with no shutdowns. Blowing a small stream of air on the plastic area behind the LCD resulted in unlimited recording time in warmer ambient temperatures. He even 3D printed a base plate that used a small laptop cooling fan to blow air on the back plate that allowed unlimited recording times.
You’re just oversimplifying the issue and then extrapolating far reaching conclusions and then assuming you’re not only correct but in possession of all the data.
I have watched many videos from the person who made this one. He is very skilled in many areas and can fabricate components with very good quality. His overall skill set is impressive. Did you watch the video? If you did then I see no way you could say he did not do about as thorough a job as possible in analyzing the heat issues, fabricating a solution and then testing the results of its application. There really is not much assumption to be done after watching this video.

Lastly, if you need absolute proof, IMO, of Canon's negligence regarding this overheating issue then look no further than what they did regarding transferring heat from the processor. Canon put heat transfer pads on the memory chips but PUT NO HEAT TRANSFER PADS ON THE PROCESSOR! The processor in the R5 is sitting in a tight space cooking away with a air gap between it and any other components. This is an insane level of engineering negligence and even a simpleton would have known this is a terrible omission. As I said, Canon's engineers aren't this incompetent. I see no way this wasn't an intentional gimping of the camera to protect their Cinema line.
 
The few people who would buy a hybrid over a cine camera have far more issues to look at.

No built in ND filters. No XLR ports. No SDI. No video style batteries.

I agree there are better video recording devices. This said Canon, IMO, seems to have intentionally gimped the R5/R6 and then lied to us about why the overheating issues exist. The overheating issue is obviously not an insurmountable engineering problem when a guy making YouTube videos comes up with a not so unique solution that seems to have solved much of the problem.

The big advantage Canon has over this YouTuber is they can tweak the internal design to make what he did much more effective. The guy in the video made a good point. He said Canon could have used a heat tube that routed heat to the base plate where they could have provided cooling measures to transfer heat out of the body. Then designed a base plate mount device with a fan in it to enhance the cooling further like he did. He pointed out Canon could have probably sold this device for $300-$400 and made a ton of money from it. Now, I bet some enterprising company will offer a mod service and the cooler if this proves to be a viable solution to the overheating issue.

Like I said he might just be cooling the heat sensor.

If you look at the LensRental blog piece the card slot after 25 minutes hit 57C with an ambient of 22. The cards have an operating range of mids 80s. What are the odds the cards didn't over heat?

The camera might not even be tracking this since it assumes the camera will have already shut down.

He took thermal image readings of the processor and PCB covering it along with other image readings to include the rear of the camera covered by the LCD with the camera reassembled. This is independent of the temperature sensor in the camera and presents actual temperature readings. His analysis of actual temperature readings was accurate enough to indicate the effectiveness of the fix he applied with reasonable certainty, IMO. This was further confirmed by the increased recording times he witnessed.

I don't see where the card temps are relevant here. The camera did not shutdown after hours of recording 8k video. The cards likely were running hot but it did npt effect the recording time in any way. This tells me either the firmware doesn't monitor the CF temperatures relative to the camera overheating or the CF cards don't heat the camera enough to shut it down. I think he said he recorded video for four hours. If the CF card didn't melt down in four hours of continuous recording or cause record errors then I don't see where CF temps are relevant to the shutdown process.
The camera might not even be tracking this since it assumes the camera will have already shut down.
Does it matter if it tracks CF temps? It appears it does not or the card does not overheat enough to effect recording time or to cause card write errors due to overheating.
 
It matters if the damage is happening to the cards or the slots. It matters if the reason the camera isn't tracking the slots is because the designers assumed the camera would have already shutdown.

It's a relatively small body. The odds are they picked one spot for the temperature sensor and a safe cutoff. If you don't change the system that works to protect the camera.

Very few people are buying this camera for four hours of use. Before anybody can claim this is a "fix" somebody needs to show long term health of the camera.

I just have to disagree with you regarding the importance of CF temperatures on the overheating issues in the R5. The CF temperatures had no relevance to the camera overheating after the fix was applied. If it did then the camera would have not recorded continuously for four hours and done so without any write issues to the card.

The number of people who believe a thing does not indicate the truth of a thing.

I didn’t clearly explain myself previously, but one potential effect of moving heat to the exterior of the body could be that users could simply believe there is something wrong with their camera. A company must consider the cost of the perception of design flaws and/or users constantly sending their camera in for service when it is not required.
Also, this fix appears to have worked under the firmware's heat control measures being applied so I tend to lean toward the application of this fix not affecting the long term reliability of the camera.
That is a conclusion unsupported by any factual evidence. Canon made a firmware fix designed for the camera AS CONFIGURED FROM THE FACTORY. That means that they knew what to expect from an unmodified unit and in no way implies they took into account other factors like extended running time at high temperature while components are pulling current. Hot components, ones not cooled to their designed working envelope, were not designed or tested for those conditions.
If fact, it will probably increase its long term viability by keeping the heat spikes to a lower level.
There’s no reason to believe that. He tested his heatsink in an air conditioned room. I would imagine plenty of folks would shoot outside on warm days or in the sun. The tests he did were extremely limited in their scope.
All it would take is to design a heat tube to route heat to an external surface of the camera. This is done in smartphones as an afterthought.

Smartphones generate a lot of heat and it is done in a much smaller, tighter space.
That’s not actually true. They are far thinner than a camera body. They have far more efficient chips.

LOL No, you can’t.

They are also specifically designed for the exact component in which they will be installed. Volume matters.

You are not in possession of all of the design considerations, operational parameters, testing requirements and results, and yet this one dude doing one mod and conducting extremely limited testing is more valid than all the tests and engineering you have no access to. Got it.

Look, I mean no offense. I also know it may look like I’m just “defending Canon” but here’s the God’s honest truth. I’ve been involved in design projects before that appeared from the outside to be fairly simple. I’ve worked with engineers for years on solutions to problems that appeared simple and then sat in rooms with high level executives with no engineering experience making the most obvious suggestions one could imagine. I had to tell them “we could do that, but then these twenty things would happen that would need solutions and it would take this many years and a few million dollars if that the direction you want to go.” Or I’ve had to say “no, we can’t do that because the material you’re taking about has these properties and would be entirely unsuitable for the specified requirement and tests this must pass.” I’ve seen amazing new technologies that appeared to solve all problems, only to discover that using it would mean increasing this one dimension by an inch and that alone would require huge redesign costs and monumental modification costs to existing hardware....so maybe we just use slightly older technology and save years and millions of dollars.

It’s just not as simple as you make it out to be. But yes, it is still possible that Canon cut corners. It’s just as likely they allowed the heat to stay where it is for a very good reason. Either one would be very difficult to actually prove.

This is not a case of believing. We have empirical data to show the fix worked. This is indisputable at this point. That is unless the person in the video is perpetrating a complete fraud which has a very low probability of occurring.
I didn’t clearly explain myself previously, but one potential effect of moving heat to the exterior of the body could be that users could simply believe there is something wrong with their camera.

Heat transfer to surfaces is done with many hand held electronic devices. This isn't new engineering at play. Canon has a multitude of ways to extract heat from a camera. They chose to do none of them and even ensured the processor would overheat by not even having any heat transfer material be in contact with it. Why would the engineers use heat transfer material on the memory chips and and not a baking processor? This makes no sense at all.

A person with limited resources identified the source of the problem and fabricated a fix for the overheating issue. So far it appears to work very well. If his work is legitimate and effective then we will see more of this type of modification occurring. His way of handling the overheating issue will be vetted over time.
Also, this fix appears to have worked under the firmware's heat control measures being applied so I tend to lean toward the application of this fix not affecting the long term reliability of the camera.
That is a conclusion unsupported by any factual evidence.
Some things take time to vet out. Did you miss where I used the word "appears?"
Canon made a firmware fix designed for the camera AS CONFIGURED FROM THE FACTORY. That means that they knew what to expect from an unmodified unit and in no way implies they took into account other factors like extended running time at high temperature while components are pulling current. Hot components, ones not cooled to their designed working envelope, were not designed or tested for those conditions.
Well, the fix appears to work within the parameters of the updated firmware. This indicates the modification may not negatively affect the overall function of the camera. He recorded 8k video for four hours with no indication the camera was damaged or compromised in any way. The proof is in the pudding as they say. Time needs to pass to see long term effects of applying this fix. As of now, it looks to be a viable solution to the problem. Also, if this fix reduces the amplitude of the heating cycles in the camera (which the data he presented indicates) then this will likely increase long reliability of the camera.
If fact, it will probably increase its long term viability by keeping the heat spikes to a lower level.
There’s no reason to believe that. He tested his heatsink in an air conditioned room. I would imagine plenty of folks would shoot outside on warm days or in the sun. The tests he did were extremely limited in their scope.
Sure there is. Heat cycling in electronic devices is one of the main causes of component failure. Your logic regarding testing is flawed. He should test his fix with consistent ambient temperatures first (i.e. indoors in a controlled environment) to determine its effectiveness. Why would he not do this? Then he operated the camera in a warmer environment to further analyze the effectiveness of his fix. This is why he came up with an externally mounted enhancement that blew area over the area behind the LCD which proved to be very effective in cooling this area and increasing recording times in warmer ambient temperatures.

Have you even watched the video?
All it would take is to design a heat tube to route heat to an external surface of the camera. This is done in smartphones as an afterthought.
Which produce far less heat.
Smartphones generate a lot of heat and it is done in a much smaller, tighter space.
That’s not actually true. They are far thinner than a camera body. They have far more efficient chips.
They generate a lot of heat in a very confined space. Thermal management in a smartphone is critical to its proper function.
It looks to me like the lack of applying effective heat management was intentional because the engineering and cost to add this type of cooling system would be minimal.
You don’t know that nor do you know the design considerations at play. Also, cost and profits matter.
I can infer it with a decent amount of surety
LOL No, you can’t.
Yes you can. It recorded 8k video for four hours straight when a stock camera can only manage 20 minutes in ideal conditions. Dismissing this shows me you don't understand the implications of this feat. Did you watch the video?
because a guy actually did it for less than $1 in parts and installed it with virtually no interference with existing components. Heat tubes are manufactured by the billions and cost very little per unit to produce.
They are also specifically designed for the exact component in which they will be installed. Volume matters.
The fact this guy hand fabricated a fix from >$1 in materials that fit into the dead space of the camera body with not interference on existing components means Canon could have done something similar as an afterthought. This cost to Canon of doing this in a $4k camera is minuscule.
A cost easily absorbed into a $4k camera body.
You’ve got profit reports on the R5?! Please share with the rest of us.
You are making a very poor defense of Canon here. Heat tubes are manufactured by the BILLIONS every year and installed in devices costing 1/40th the cost of an R5. You lost this debate before it even started.
As for fitting a heat tube into the body, it would be simple to do as it is done in smart phones which have far worse space constraints.
Especially if a guy with hand tools and limited resources can do it.
What testing did he do? How will people react to a 50 or 60 C hot spot? How will the electronics react to extended exposure to heat while simultaneously under load?

The lowered temperatures after the fix as applied allowed longer recording (and only five minutes wait periods after overheating) compared to stock conditions.

It is Canon's prerogative to limit capabilities of a camera if they choose. What irks me is how this camera's video capability was up front and center in the marketing effort. They used its video prowess to entice people to buy the R5. The R5 is a very good camera but $10 worth of parts would have let it live up to its billing.
You’ve fallen into a trap by making that assumption. And firmware changes made the R5 much more usable.
The guy actually tested the results with both firmwares installed after the fix was applied. The updated firmware resulted in much longer record times than the original firmware with the fix installed. This is empirical data so there isn't a lot of assumption being made on the results of this addition to the camera. The camera recorded 43% longer with the fix and updated firmware than it did stock with the updated firmware. When he tested the camera in a cooler room it ran continuously with no shutdowns. Blowing a small stream of air on the plastic area behind the LCD resulted in unlimited recording time in warmer ambient temperatures. He even 3D printed a base plate that used a small laptop cooling fan to blow air on the back plate that allowed unlimited recording times.
You’re just oversimplifying the issue and then extrapolating far reaching conclusions and then assuming you’re not only correct but in possession of all the data.
I have watched many videos from the person who made this one. He is very skilled in many areas and can fabricate components with very good quality. His overall skill set is impressive. Did you watch the video? If you did then I see no way you could say he did not do about as thorough a job as possible in analyzing the heat issues, fabricating a solution and then testing the results of its application. There really is not much assumption to be done after watching this video.

Lastly, if you need absolute proof, IMO, of Canon's negligence regarding this overheating issue then look no further than what they did regarding transferring heat from the processor. Canon put heat transfer pads on the memory chips but PUT NO HEAT TRANSFER PADS ON THE PROCESSOR! The processor in the R5 is sitting in a tight space cooking away with a air gap between it and any other components. This is an insane level of engineering negligence and even a simpleton would have known this is a terrible omission. As I said, Canon's engineers aren't this incompetent. I see no way this wasn't an intentional gimping of the camera to protect their Cinema line.
You are not in possession of all of the design considerations, operational parameters, testing requirements and results, and yet this one dude doing one mod and conducting extremely limited testing is more valid than all the tests and engineering you have no access to. Got it.
Neither are you. Got it? You have no clue if Canon intentionally gimped the R5. I have a clue because a guy fabricated a fix for its overheating problem in his house using hand tools and >$1 in materials. I have more of a clue than you do at this point.
Look, I mean no offense. I also know it may look like I’m just “defending Canon” but here’s the God’s honest truth. I’ve been involved in design projects before that appeared from the outside to be fairly simple. I’ve worked with engineers for years on solutions to problems that appeared simple and then sat in rooms with high level executives with no engineering experience making the most obvious suggestions one could imagine. I had to tell them “we could do that, but then these twenty things would happen that would need solutions and it would take this many years and a few million dollars if that the direction you want to go.” Or I’ve had to say “no, we can’t do that because the material you’re taking about has these properties and would be entirely unsuitable for the specified requirement and tests this must pass.” I’ve seen amazing new technologies that appeared to solve all problems, only to discover that using it would mean increasing this one dimension by an inch and that alone would require huge redesign costs and monumental modification costs to existing hardware....so maybe we just use slightly older technology and save years and millions of dollars.
I have a B.S. in engineering and have been designing for decades. The situation here is far from looking favorable that Canon did their best in managing the heat in the R5. Simple heat management measures that are done as an afterthought in today's electronic designs were completely left out in the R5. This all but irrefutable fact at this point. What this Youtuber has done is shine a very bright light on this having occurred.
It’s just not as simple as you make it out to be. But yes, it is still possible that Canon cut corners. It’s just as likely they allowed the heat to stay where it is for a very good reason. Either one would be very difficult to actually prove.
It was simple enough for a guy with limited resources to dismantle the camera, analyze the problem and fabricate a fix that appears to be quite effective.
 
It matters if the damage is happening to the cards or the slots. It matters if the reason the camera isn't tracking the slots is because the designers assumed the camera would have already shutdown.

It's a relatively small body. The odds are they picked one spot for the temperature sensor and a safe cutoff. If you don't change the system that works to protect the camera.

Very few people are buying this camera for four hours of use. Before anybody can claim this is a "fix" somebody needs to show long term health of the camera.
Some people are simply angry about the camera and will allow confirmation bias to “prove” that they are justified in their anger. There is no logic or evidence or rational argumentation that will convince them they are, or even might be, wrong. In this case, you’ve made a reasonable argument and sited evidence that supports at least the possibility if not likelihood that it is both plausible and more likely than not. Definitive proof one way or the other would require much more rigorous testing, but stating conclusively that Canon with failed at their engineering or behaved maliciously is simply unsupported by evidence.

I've never had an issue with overheating, Some say putting a small computer fan next to the card door improves times and recovery times.

If I ever do have an issue that is my plan. But I can always wait that extra 15 minutes, so no big deal.
 
For some reason you are incapable of acknowledging that while the video indicates a correlation, there is absolutely no evidence of causation.

As another poster stated, the hottest area on the camera is the card slot, and we have no idea how the temperature is sampled or where it is sampled. Also, the lensrental.com blog indicated the internal temperature at shutdown was 63C, the card was 57C, and external readings were over 40C. Depending on where the sensor is located and what that temperature meant for other components when engineers conducted their testing (it may be that 50C on the sensor meant other components not in proximity to the sensor were much hotter) the copper heat sink solution could easily take advantage of the sensor and firmware to extend shooting time without solving the problem the shutdown parameters are meant to solve. Add to that implications around failure, longevity, various shooting environments, and the duty cycle for which the camera was designed....you just don't have nearly enough information to draw the conclusions or even the "appearances" you're claiming.

I've known a lot of engineers. Some are taught by knowledge and experience to be skeptical and humble, while others have an exaggerated sense of their own expertise. It's similar to doctors who develop a God complex but fail to understand being extremely talented in one area does not mean they're great or even good at anything else....I've known those people, too. You've seen an interesting idea that shows some promise and improvements, and then you extrapolated far too many conclusions from it without considering that there is just a whole lot you don't actually know. I'll just ignore you from now on and save myself the attempts to point out flaws in your reasoning. I'd suggest you do the same.
