Hello Luca,
Glad to get your message.
Do you have the PCB photo of this card?
We have the water block (BP-VG3080TIGXH) for GALAX GeForce RTX 3080 Ti HOF.
But we are not sure if it is compatible or not.
So if you have the PCB photo of this card, we will check and reply to you.
Here is our email address.
