Using the tripod mount, fix a strip of 3mm aluminium strap to the camera base, cut to size to fit one or two TEC modules with heatsinks and fans. The camera is then set in a smaller box, putting the cooling in contact with the body of the camera, improving thermal resistance, dispensing with volumes of air. It would be necessary to exclude moisture from the box, of course.
If you were concerned about cooling directly to the camera base, a gap of 0.1mm would be adequate, separating the strap from the base. A few holes tapped to fix the heatsink/s.

I'd be concerned with maybe uneven cooling effect from the base but worth looking into for sure. I've also have got heaps of laptop cooling units from chuckouts at work. Might look into that as well.
No luck findinga similar enclosure to Garys at Bunnings, I'll go see a big electrical wholesaler tomorrow maybe. I think it's the best option for efficient cooling to lowests temp.
