Title is a bit misleading - while he did attach watercooler to R5 to unlock unlimited 8K, later in the video he achieved the same thing by using custom internal copper heatspreader and small fan attached to bottom of the camera body in 3D printed enclosure - that is much more useful and less "gimmicky" solution.
Even with just custom heatspreader and without fan he was getting 40 minutes of recording, then had to take 5 minutes of break and could record another 40 minutes, as opposed to 25 minutes with hour long breaks before modification.
- m463 6y agoI think he probably went for watercooling first because it has the promise of silence. A fan on a video rig sounds horrible, and probably sounds horrible too. :) It's funny how all the pc watercooling awareness is spreading. There are lots of videos about the controversial process of applying thermal paste.
- terramex 6y agoFan on video rig is a fairly standard solution, used by both Blackmagic and RED cameras.
- CarVac 6y agoAs far as I know, fans like that are used to run between takes, not during them.
- geerlingguy 6y agoCinema cameras are also very rarely used very close to an omnidirectional microphone—a slightly audible fan would not be picked up by the external lav and shotgun mics recording the talent / action. Some people recording with the R5 or other more compact systems might rely on internal mics or a shotgun mounted atop the camera for audio, and that definitely picks up sound emanating from the body, at least a little. Many lenses' focus motors are loud enough to be annoying in onboard video.
- nottorp 6y ago"The promise of silence" is well said. It may be better than tiny fans, but for pcs you basically add pump noise and move the fan's location a bit. You can obtain the same effect with 12cm+ fans in a well designed case without the risk of leaking.
- philjohn 6y agoA good D5 will emit hardly any noise when running at 30-50%, and you can have 140mm fans on 140mm wide rads running very slowly (400-600rpm) and keep everything very cool. I've done both air only, with high quality fans, and now have. custom loop - the custom loop is far quieter, even at load. And it was fun to do.
- ashtonkem 6y agoPCs also live in cases, and can be moved a non-trivial distance away from the peripherals they drive. Not so much for cameras, whose placement is driven by other factors
- alisonkisk 6y agoMicrophones can be moved away from the camera.
- nitrogen 6y agoVery true, though a bit more difficult for a one-person team if they need to move around.
- TaylorAlexander 6y agoWell for filming people you can use a wireless lav.
- im3w1l 6y agoI wonder if the processor (which was the hotspot) couldn't be moved from the rest of the camera though.
- nicoburns 6y agoI think he went with watercooling first to simplify his testing and make sure that his fixes weren't failing due to inadequate cooling power.
- IgorPartola 6y agoHell we are now seeing water cooled 3D printer kits.
- bufferoverflow 6y agoMany cinema cameras have fans in them.
- codeulike 6y agoThe hacked-together watercooling was the experiment that proved that a better heat solution would lead to unlimited filming.
- swiley 6y agoActive cooling in handheld devices is really underrated. I understand not having it if they're water proof but most aren't.
- rtkwe 6y agoA big issue is most handheld devices are already packed to the brim with battery filling most of the space left over after the electronics are laid out so there's no space left for meaningful active cooling. There was a teardown of a Red camera on Linus techtips to add watercooling and the contortions required to pack everything in with the cooling was amazing.
- _visgean 6y agoNot sure how active cooling plays with image stabilization but my guess would be that not very well - or rather it takes quite some engineering to make it play nicely. Also battery life...
