Yes, the Corsair iCUE H100i Elite Capellix XT liquid cooler with the manufacturer number CW-9060072-WW is compatible with the AMD Ryzen 7 7800X3D. This cooler supports the AMD AM4 and AM5 sockets, which include the Ryzen 7 7800X3D.

It depends on whether you receive it functional or not. I received it non-functional.
