I have thrown in a couple of edits, sorry. Get thinking and ideas keep coming to mind. The thinking (I believe) is sound and has proven itself on the dual watercooled idea. Take Care and I highly recommend you through up a thread and direct it so it does not get off track. I believe that there are others that would love to help (in a serious fashion), just don't let some take the thread where you do not want it to go. I.E. keep it on track. Take Care and if I can be of any assistance.
If you get stuck, might use these thoughts. Candle, yellow is insulation for blue (intense heat). Candle represents xp2200 heat profile. Stove, Lower height but wider area, represents xp standard. Duron, stove on low. Kill the yellow, (insulator) and the profile of the blue must change. XP2200, profile is candle, intense over a small area. Picture tec, amount of tec cooling area brought into play on a small intense area? Tec is taken out as cold plate (standard setup) is penetrated and small area of tec must cool intense heat. Must bring full 48mm of tec into play to achieve cooling. Idea, overlap tecs. Double cooling in overlapped area and candle can not penetrate tecs. Result profile changed to small area at bottom of tec where arcs do not overlap and heat spreads out. Insulation is narrow immensely. Blue is very low and stove type situation (on low flame) is achieved.
