It would be safer to drill a hole in my head as it would not damage anything important.Jokes aside, even a ten to fifteen degree C drop from an ambient of 20 to 25 on a summers night would be worthwhile.My thought of using the tripod mount hole to hold the whole assembly has been done.Thanks fringe_dweller for the reference.So I will modify the design to do the same thing cool the bottom of the camera by conduction and direct cold air on to the back.More thought needed.I just wanted something that would easily attach to get a moderate amount of cooling for hot summer nights.
