very interesting, I dont quite follow how you desicided on temp, and hot sopts, and so on. One one of your pics I see a hot spot by one of the inlets, so very far from the actual heat source. And what bease thickness are you thinking of, because the more base material, the more heat will go outwards.

or maybe I am just not understanding what you are tying to illistrate.
