I am wondering if a cooler bag or a foam filled plastic lunch box can do the trick here?
Otherwise perhaps I will have to follow Gary Honis way and simply try and build a box out of light weight aluminium and then mount the camera inside this.

I've done a lunch box cooler but it's too shallow for a rear fan and not enough room for sufficient foam to be useful internally.
@PeterEde > It doesn't need much space and in fact the less the better withinn reason. It's just more volume to cool. I'd be more interested in getting more airflow round the whole camera body because the current setup means that only the back is cooled ( best point) but there is a lot of thermal mass to cool so it slows down the process. The author mentions wrapping the camera in foil but there are probably some other options I will look into for my version.
