markebyThe cold plate on the factory cooler of my 1080 ti is round and fits just inside all 8 screws on the copper portion. The photo of the cold plate for the 3090/3080 hybrid kit is square but covers the same exact surface as the die on my 1080 ti. That is if the 12 screws that attach the copper/plastic component to the metal plate are in the exact same position. The copper puck on the 1080 Ti measures 54mm with a 2mm drop on the cold plate. The plate it screw into measures 56mm and the screws are 15mm apart around a diameter of 61mm. If the measurements are the same and it is a simple 12 volt powered pump & radiator fan then, it would be a drop in replacement Even if the electrical isn't quite the same it is still possible to make it work.
