  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

I just wanted to get some info on what users are doing about the overheating issues with the camera. Apart from shading it or using a fan on the body is anyone working on an external heatsink or cooling device?
There's probably going to be people saying that they haven't had any heat problems but I've heard of 2 in the last week but that's probably because I live in Texas ( it was 101 yesterday ). I have my 1st real Red shoot next week and cooling won't be an issue but I'd like to find out my options for later in the summer.
Maybe something like this?http://www.bigbruin.com/2007/ttixoft_1
Thanks all,
Shane.

I'm throwing ice packs on top of the camera. I've gotten the body hot warning a lot. We were doing a music video this weekend in a 90ish degree interior location and even with the fan set to "HOT" blowing at high speed all the time we still were getting body hot warnings. The ice packs helped and we never had to stop shooting. I did power down between setups though.

I used the hot/cold packs that stay flexible after they are cold. The drag is since they are also hot packs they retain heat after they heat up from being on the camera.

People don't seem to post about this issue much, but I did hear from an AC that he was on another RED shoot out here and they had the same issues.

When does body hot show up and when does the camera shut down?
Is there any reason not to keep shooting while the body hot warning is on?

Also, does anyone know of a flexible cool pack that isn't also a hot pack?
 
Would you be able to use something like this the the RED usb port?:

Or is all of your money is sunk into RED related, a DIY option:

I'm sure there are more powerful USB fans out there, and that there would be a noise when connected to the camera (i.e. rattling or a buzz), but for inbetween takes as some sort of cooling, does it seem like these may be an option or would help?

I'd be surprised if blowing a little warm air on a hot aluminum camera body would do anything. Think about what it would take to equal the cooling power of an ice pack.

Maybe EPIC will have a liquid cooling system built into the body.
 
Still air is a good thermal insulator. The difference in heat transfer between stagnant air and even a small breeze can be significant... you can feel this on a hot day when a slight breeze picks up. Depending on the ambient temp, I think a small fan (and maybe some vertical fins on the top of the camera) could easily make the difference between "hot but still working" and "too hot".

However, this is just speculation and I haven't tried it. There is some ambient temperature above which you will need to use ice, water, gel pack or other active cooling system.
