heat source way too hot

true. But also I may have to add some of the surrounding metal, as that will act as heat sink as well. But I suppose after the moving air radiation is the 2nd biggest contributor and then heat loss to the still air outside the box.
Edit: setting the feet of the reactor to same temperature as the air inlet reduces the temperature a lot. I guess the truth is somewhere inbetween. The reactor sits inside a metal box, that box is bolted to a machine. So some of the heat will go there.

I added a round plate 1.5mm thick and set its edges to ambient temperature. This removes about 150W from the reactor. May be a plausible standin for the attached metal structure. Its just so many assumptions, no guaranty there are 500W coming in to start with. But at least now its at 80 centigrade. Good starting point if I manage to find out, how much heat is generated and then verify my model.
