    canon r5 tiltafan - Tilta shows off a cooling module for the Canon EOS R5

    Unless you've been living under a rock, you've probably heard about the heat issues with the Canon EOS R5 when recording high-resolution 4K or 8K video.

    I haven't touched the camera, so I'm not jumping in with an opinion. However, what I have noticed on social media is very different results and conclusions about using the EOS R5 as a video camera regarding heat. There have been those that have said it is unusable for videography work, and there are others that have said they haven't had an issue and have loved shooting with it.

    Knowing social media, it's probably somewhere in the middle.

    Now we have the company Tilta that is showing off a fan that quickly mounts to the rear Canon EOS R5 when the screen is flipped out. As you can see by the images below, it's pretty and may look like it it'll be an effective solution, but I don't think it would have any real effect on cooling down the Canon EOS R5.

    I'm not an engineer, but I do have some cooling experience with motorsports and computers. Simply blowing environmental air at the camera without any way for the camera to exhaust the heat likely won't have any real effect on cooling the camera down.

    *Update* Some have noted on this thread that it's a Peltier type cooling solution, but for the most part, plastic is an insulator, so I'm not sure how effective a Peltier cooler is going to be at drawing the heat through the plastic.

    Tilta claims that this module will have a maximum cooling effect of 82f/28c. These numbers don't really mean anything, as I don't know how hot the camera actually gets inside. They claim to be able to reduce the heat of the camera down to 59f/15c in one minute. I just don't see it.

    I could be totally wrong!

    I do wonder if someone out there is going to take the EOS R5 apart and figure out a way to put vent holes in the camera, I believe that would probably have a more positive effect on dissipating heat than simply blowing air onto the exterior of the body. Holes would obviously go against weather-sealing, but there are some smart people out there that may come up with a smart solution.

    For now, here is what Tilta is thinking:

    The next camera system to be supported by our Tiltaing collection of camera accessories is the new Canon R5. Featuring a new mirrorless CMOS image sensor and 8K RAW / 4K 120P capabilities, Canon has made an attractive tool for video content creators. Camera cages, handles, and other accessories will be made available for this new camera, along with a brand new cooling module.

    Created to extend recording times and help mitigate overheating, this easily installed module combines a fan, heat sink and temperature sensor. It will activate as needed, and can be removed with ease. Learn more about this new feature and look for more information about more Canon R5 components and their availability soon.

    1. Simply blowing environmental air at the camera without any way for the camera to exhaust the heat likely won’t have any real effect on cooling the camera down
      Yes same as i thought. but we should wait for someone to test it out.

      The exploded view shows a Peltier module, so it’s active cooling. The fan is cooling for the hot side of the module, not the camera.
    5. Heat conduction is somewhat like a series/parallel resistive circuit preceding the location where this heatsink is placed so its efficiency will be very much dependent on the path from the heat source to the location of the sink. Intuition says it's not going to be super.

    6. The problem here is the plastic on the outside of the camera. Plastic for the most part is an insulator, so a Peltier cooler is not going to draw heat through the plastic.
      There is a great deal of ambiguity here. What type of "plastic", how thick etc. will influence the thermal resistance and we know none of this so it's kind of pointless to speculate.

    7. So my wife has a mini fridge with a Peltier cooler which isnt much bigger than that. I had to replace the rear fans bc they were going bad, so I played around with it. So I think it there is a fair chance that it will work. Not as good as a C200 body but you will notice a difference.
    8. Surely they’d have thoroughly tested the overheating aspect while they were developing the camera right? I’m skeptical that it’s as bad as some people are saying. Could be that the preproduction firmware on the review bodies is not as well optimized as the production models. Inefficient software can definitely cause a device to overheat.
      A lot of the early reviewers probably want to cash in on the drama and hype. I’ll be waiting for Gordon Laing’s in-depth review. He’s the most fair and drama free camera review channel I’ve seen so far.
    9. I wonder if is it possible to cool the body like that, there is no real connection between the heat source and the fan. Other thing is that the size of the fan don't allow the user to look into the OVF. Anw have teh screen open all the time.

      The screen is folded out. This cooler goes where the screen was before.
    12. Agree. Without a direct connection to the processor this will most likely not be very effective. To get the heat to escape fast you need heat sinks or heat pipes (like the 1dx ii) on the processor as well as a fan. Canon should just make a version of the R5 that ditches the weather sealing and has holes or exhaust it in to end this silly debate for hybrid shooters.

      I don't think that the heat will transfer fast enough through the body. Plus I'm gonna guess that the R5 is designed to exhaust heat forward (I think the 5d IV did this) instead of backward.
    14. I have my doubts, but a true test of 8K video run time with and without the cooler would be the best test. If it extends the run time by 50%, it might be worthwhile. 10%, maybe not.
    15. This solution works, if the camera has a good thermal interface to the backside of the camera.

      Drilling holes into the camera wouldn´t help much.
      Right. A conduction path from the heat generators to the cooler has a chance of helping. However, relying on internal convection will be minimally useful. And as was previously stated, condensation can become an issue if parts are cooled below room temperature. Interesting though that some entrepreneur jumped on this right away. Was there anticipation of an issue? I’m skeptical that many will find this to be a practical answer if they do have overheating problems in their use. A more likely solution would be an external recorder, or a true dedicated video camera IMO.
    16. 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).
    17. There is a great deal of ambiguity here. What type of "plastic", how thick etc. will influence the thermal resistance and we know none of this so it's kind of pointless to speculate.

      This is worth emphasizing. After all, it is very much in Canon's own interest to use materials that help with heat dissipation.

      Also, my from my experience, this cooling device is placed perfectly. That is only based on my 600D, which did get very warm in the area behind the screen when being pushed by Magic Lantern.

      Also, keep in mind that we aren't dealing with a huge amount of heat here. It is just too much for the camera to dissipate it faster than it builds up. But getting around 20 Minutes of recording and further recordings after a few minutes of passive cooling makes me believe that even a little active heat dissipation will help a lot. It's the same issues flag ship smartphones are having. Asus sells a simple cooling fan attachment for their gaming smartphone and it does actually work. But as noted, not much will come from speculating either way. The cameras aren't even out in the hands of consumers yet.

      People have also had success with cooling DSLR in this way for astro in the past:

    18. I don't do video so this discussion about the camera cutting out doesn't really worry me. What would worry me is if the sensor gets warm and it increases the noise in the circuits, which would be noticeable at lower isos.,
    19. The only realistic thing for Canon to do (besides bending their heads down to their knees and apologizing) is to discontinue the model and come out with a quick successor - the R5b , one that will have vents and a fan. The PR damage is already done but if they act fast they may get some to look past the initial blunder.
