    Well, well - actually I did test it with my R5. Firmware 1.1.0 - and guess what: it works like at charm.
    Let the camera overheat in the 120fps mode. Camera gets really warm. I guess I had something like 20 minutes in total (had to erase the clips from my card again and again). Anyway, after the camera overheated I opened the battery door, blocked the little latch to make the camera think it was closed. Went into the menue, forwarded the date by one full day. Confirmed. Took the battery out, waited some 15 seconds. Put the battery back in, closed the battery door. And here it was: Camera still warm after a short pause of 2 minutes (the time it took to go through the procedure) and what do I see in the display: Full recording time, no overheating sign. LOL. Canon, You've got a loophole there. Does the camera even bother to measure zhe temperature at all?!

    So this is my final result with the R5 running on 1.1.0:
    After 1 1/2 hours I gave up. Couldn't make the camera overheat at 19°C room temperature in the 4K HQ mode.
    Camera started at 21°C.  After 1 hour 30 minutes EXIF reports 61°C and didn't go above it. While it said in photo mode that I had 0:00 minutes left, it showed 1:00 in video mode but recorded nonstop 7 minutes before I stopped, deleted the clip and started right again with another 1:00 minutes left. Didn't even need to fool the camera. 
    But now I was interested in the real recovery time.
    After 10 minutes (indicating 3:00 shooting time left) the camera went back to 41°C (all doors open, camera switched off)
    After 20 minutes (20:00 shooting time) the camera ist at 33°C
    After 30 minutes (20:00 shooting time) the camera is down to 29°C
    Weird detail: Toggling between photo and video mode: video mode always shows more recording time than the photo mode. f.e. 10 vs 20 minutes.

    I'm so sorry you feel offended by my previous post.😘
    As you admit yourself not having any geek knowledge to determine the exact usage a NVMe drive; I was just trying to clarify the post you where sharing. It was, in no way, an attack to the filmmakers community that knows shit about technical stuff but still keep re-posting absurdities.

    My only goal is to make this great forum a better place with my real life experience (and love.🥰)

    I always had a commitment to support the filmmaker community. I can only bow to your message and ask you for ultimate forgiveness.🙏 please, please.

    I hope my personal hack last Sunday, on this forum, with an easy way to reset the Canon R5 timer is enough to be absolved.

    Please accept my full apologies if you felt I was having condescending tone or look like I was some kind of geek. Even if my degree was related to computer science, believe me; I have tried to stay away from techies and other complicated process my entire life. A quick fact check on my previous post and personal blog should reassure you. 
    The truce is far less interesting. It's almost sad, even. 
    I'm a very simple camera guy. I have been shooting only few days so far;
     made a count last year and it was just about 1,000 shooting for the past 15 years. I have put this in my humble website if you like to give a look by following my profile name. I know it's a low and this is obliviously due to my lack of skills as a cameraman too. I really sucks at everything I commit.
    My client are obscure companies like Disney, IBM, Apple... as you may check. My eyes start to be full of water when writing this down. 

    The "Filmmaker" title's is way beyond my reaches as my old age is now a translation of back pain and loss of eyesight.
    I might be retiring without even getting the glorious title of "DoP". Ok, you are making me cry now. It was not a good idea to write about this.😢

    And you know the worst of all; I don't even own a Canon R5. I had to ask for help here from a fellow member to test and validate my findings. Only this way it have been proven to work.
    The saddest thing of all;I have invested on two Sony FS7's few years back and may never be able to shoot with a DSLR. I',m stuck using cine lens and other heavy gear forever.
    That mean that I will not use my hack for myself and will donate the entire result to the the community I was hoping to join once. 

    Thank you for listening. Here is love again ❤️💖❤️for you and the beautiful movies you have been making all over the world that I can see nowhere.

    Today a large part of the social media comments, articles and reviews on controversial subjects are written by diverse armies of paid shills, "fact-checking", creating fake news, exposing "fake news" with fake news, whitewashing their employers and smearing critics. This was documented by The Intercept in 2014 and by political campaigners in 2016. Corporations like Google, Twitter and Facebook, powerful private interest groups (Club of Rome, climate change, global taxes, vaccinations etc) and state agencies, spend hundreds of millions for this modern and extended PR.
    Canon last year spent over 400 million dollars on public relations and advertising. Almost double what the Bill and Melinda Gates foundation pays, which is in the media all the time. The latter has given over $2 million to groups such as fact-checker Africa Check ($1.48 million), media company Gannett ($499,651), and the journalism school the Poynter Institute ($382,997). In return, when you google "gates foundation fact checkers millions", the second link goes to the Poynter Institute-owned fact-checker Politifact.com, where their "factcheckers" whitewash the Gates Foundation.
    The only reason we ever knew that, for example, the Clinton campaign was hiring professional shills to pose as real Hillary supporters online in order to deceive people and manipulate public discourse is because they were forced to disclose it due to FEC regulations.

    The CPU's topside thermal pad was still stuck to the aluminium plate in the Chinese disassembly:
     

     
    Continuing the disassembly, there is another thermal pad right under the CPU PCB leading heat to the larger metal plate on the underside.  In addition to the top- and bottomside plates, the copper layers of the PCB itself conduct heat from the components.

    With FW V1.1 I think the gap between how hot Canon lets the camera run and how hot the camera should run (to avoid IC longevity issues) has narrowed. Canon's original thermal management firmware implementation was quite clumsy and too coarse for lots of scenarios. They addressed some of those scenarios with better ambient temp sensor integration into the algorithm. There's still room for improvement, which hopefully Canon will do eventually. Until then I think the new workaround is a great stopgap, including for situations where you absolutely have to get the shot and don't care about an occasional short-term temperature spike.

    But this is interesting: There is another overheat symbol appearing after 15 minutes into my seconf 120fps run: one without the camera, a thermomter only. After stopping and taking out the card (leaving in the SD card) the symbol turns white. It disapears after taking out the (very hot) CFExpress card. So it seems to be an overheat warning for the CFExpress card.

    It seems too simple to be true. But it is. There is a camera reset procedure now. Whenever your R5, R6 is overheated, just go quickly through your date change, battery drop procedure. And your camera is back on and fully operational for all video modes. No matter what card you use.
    Only if your camera surpasses 65 or maybe 70°C, that's when the real overheating warning kicks in.
    The other question of course still remains - how much can or will the camera endure in long term? But as long as you use this neat trick only to get rid of the ridicously long cool down periods I'd say it's fine.

    You again 🙂 Always appreciate your videos Matt.
    By the way - tried to make the R5 overheat at 4K 25fps HQ (at 19°C room temperature). Took me 59 minutes to get it to show the overheat warning (which appeared in the photo mode about 10 minutes earlier). Recording on CFExpress. So obviously we will need this neat trick only to shorten the cool down wait period or the "overheating due to obsessive menu use" 🙂
    BTW: Still no shutdown after 1 hour eight minutes of 4K 25P HQ. But the GoPro gave up. Overheated!

    No, No need to do anything

    It's very simple.
    Canon do a very simple calculation.
    When camera is running, a counter is setup. When the counter reach a certain level, you have a warning logo.
    If you keep recording, the Log will become a shut down. This raise a flag that I will call "Fake Overheating flag"

    At each of these step Canon is writing the exact time this occurs. Let's call it the "overheat start time".
    This is done in an eeprom that is kept even if you remove the battery. The writing occurs when you shut down with the power button. This is the mistake right there.

    There are only one way of getting the camera to work again is to wait extra time.
    Canon do a simple calculation between "actual time" and "overheat start time". This way, even if the camera is off without battery, they can keep the time running with the help of the RTC.
    It's a way of doing coding something very fast.

    They also put a conditional test on "Fake Overheating flag" to make sure changing the time during the overheat mode will not change this calculation. My best guess is that they modify the "overheat start time" with the same value the camera time is shifted in this condition only. So each tentative to play this way is not working.

    But I have the impression that the new "overheat start time" is written ONLY when the camera is power down. The new real time is written immediately.
    So by dropping the battery, you are avoiding the "overheat start time" to be written and only the last one is in the memory.

    When the power is restored, there is the calculation to see if you have been waiting enough. But based on the old "overheat start time", not the one shifted by the time modification. BOOOOM.

    So the flag is now remove and the camera can start.
    Even better, The camera is writing this new "Fake Overheating flag" value into the EEprom. So you can turn off the right way and it will restart without any problem.

    You can now shift the time back, there is no check for a possible "overheat start time" cause we are not supposed to be in overheating mode.

    So whatever card you are using, whatever R5 or R6, whatever firmware... it's working.
    That was my idea at first when I noticed that the battery drop do not save all parameters. An yes, it works so beautifully.

    I'm glad that it's working on the R5. Honestly this makes the R6 the best camera in the world for me right now ,(besides the stupid clog1 limitation). Even if they do implement a clog3 update, I'm scared that the overheat hack will be patched in it.

    This is Pictogram. I took a foto with my R5 close to that moment: 
    Not pretty - but it should have the precious temperature reading you're looking for 🙂
    Next time I will take that picture once I see the symbol again. It comes in red and also in white. And it disapeared seconds after I took out the CFExpress card.

    Well, one tester is not enough, please try to do the experience if you have a R5.
    The procedure is explained here.
    https://www.visionrouge.net/canon-r5-overheating-hack-solved/

    In short:
    - Power the camera with a external battery and close the door beside the R5 (you can also do the screw trick if you like)
    - Record video until you see the overheating logo, or even until the camera shut down.
    - Turn off the camera by using the power button so your recording parameters (ISO and so one) are saved.
    - Turn back on the power.
    - Go to the menu, Change the time of the day to +3 hours at least (or add a day)
    - Drop the power by disconnecting the external battery
    - wait 30 seconds
    - Put back the external battery. the overheat issue should be gone.
    (if not, you may actually be in real overheat situation), try in 10mn...
    Please share your findings.

    Second run, one minute after shutdown due to overheating. Runing for seven minutes now. No overheating sign. Camera very warm on the back. So obviously the camera doesn't check any kind of temperature inside the camera. If it did, it would have had to shut down by now.
