Will the pads only have contact with the fins? Will there be a plate similar to how Palit or Asus cards are? If not, wont it be super inefficient and dry out eventually?
There is already a plate. The way it is set up is PCB, Mosfets, Thermal pad, Heatspreader, air gap, fins, fans.
What you are adding makes it PCB, mosfets, thermal pad, heatspreader, thermal pad, fins, fan. There is nowhere to put a second plate.
