I am currently testing options for a low-cost cooling system. I will post the results here ASAP. I won't be offering it for sale, you will be able to DIY. Initial results look very promising. I get that Red users need this solution like yesterday. I'm sure Brian's solution will probably be more elegant and I can't wait to see it.
In Austin this summer we've had about 40 days over 100 degrees (38C), so it doesn't take long for the ambient temp to reach 105. We work in these temperatures regularly. The camera needs some sort of heat-sink to pull the heat away from the body or even a peltier system (which would require power but could be very useful.)
The real solution is probably in a redesign of the camera with better air intakes and heatsink fins on top but I doubt that that will happen.
Whoever comes up with a solution will certainly sell quite a few of the devices (at least to red owners in hot climes).
I just found someone asking about undewater housings (or at least splash proof) and the same issue (heat) popped to my mind. In a housing of some sort, air vent is very limited and the temp could raise fast. If heat does not move fast enough from CPU's and other "internal organs" of the beast into the water, the limmited amount of air surrounding the camera will conduct the heat at its worse. If shooting on land (hot days and/or geographic zones) or underwater (in a housing) I think the need for a technical solution to adress those instances is obvious, but that requires intimate knowledge of camera's inside. Only the R&D team can do that. I don't believe any outside solutions will be good enough (3rd party coolers) in the long run.
It almost looks like a nice car/powerfull engine with a small radiator (or just aquarium tubes instead of propper pipes). Let's keep in mind the "up-gradeability" of the sensor, etc. The cooling needs to be ahead the upgrades (I think).
My (tux deductible) 2c.
We also have to prepair a shoot on a rafting boat.... so we need to mount the cam in scuba cam housing or something similiar... also here the question if somebody has experience in using the housing and heat....
any advice would be great...
Jeff.. as you might know. we will be shooting out at Burning Man next week or two.....
any update? or beta test unit before then?
The top of the camera gets quite hot so I assume a cold pack tucked in there would do some real good. I keep gel packs in a soft-side cooler on my magliner when I am working the set as AC/DIT. Wrap them in a shop towel with one layer between camera/pack and more layers above. I might drape a shop towel over the top and sides as well to absorb any stray condensation.
As Shane notes, it gets pretty hot in Austin. Here's a couple shots from inside a pottery shop's shed. It hit 110F in there at one point. The shoot was MOS so we were able to keep the RED One fans spinning on HOT. The camera only started complaining at the very end while the DP was picking up some b-roll.
1st ac, Robert Rendon pulls focus while grip, Buzz Malloy handles the dolly move.
