The card is fully working. I've replaced the thermal paste and pads as I moved it from a fully water cooled setup back to its original heat sink and fan.
I also have the water cooling parts if you so desire to purchase them for another $50 dollars. It is the full back plate and cooler from EKWB, EK-Quantum Vector TUF RTX 3080/3090 D-RGB - Nickel + Plexi, and EK-Quantum Vector TUF RTX 3080/3090 Active Backplate D-RGB - Plexi. The water cooling setup comes with all the required parts and screws needed. You'll want to source new thermal pads and paste for yourself.
Feel free to ask if you wish to see the card in action when you contact me.
