1080Ti Duke backplate with almost 100mm of 4mm thermal tape attached
I finally finished this project. I used up almost 100x100mm of 4mm thick phobya thermal pad. It seems like the MSI 1080Ti Duke now has GPU idle temperatures closer to system temps and under load it takes much longer to ramp up to peak GPU temps which are maybe 4°C cooler than they were w/just the thermally non-functional backplate. I ended up covering the VRM area, and the vertical VRAM areas as well as a different type of thermal tape over the capacitors covering the backside of the GPU. I think it would make more of a difference if there were more airflow over the backplate but all it gets now is some from the sidecover fan.
A big thanks to Blameless for his help on this project.
