Default Heat spreading through pcb Insulating question.

Hi, I just built a peltier cooler for my new 9600xt that cools both the gpu and the same side ram, I have insulated the cold plate very well and I will almost be able to just use it the way I have without any conformal coating or silicone because of the way I designed it.
My question is how far will the heat spread(lack of heat) through the card? how far and how much will I have to insulate on the back side?

I am planning on trying to run this at 5v and see if it will cool it just enough before I make a plunge to full 12v then maybe a 172@12v later if I keep the setup.
Heres a few quick shots.




I made it out of aluminum because thats all I have at hand at the moment, and I am not too worried about the semi-small performance decrease at the moment.

Jon
