I have the 2080XC in the Case and can say the NF-A12 working fine. I have only a bit "noise" when I torture the graphics card over a long time. Then the EVGA fans are spinning up to 1600 rpm and they are loud.
Overall, you will need fans underneath it, because of the airflow through the case. Else you will reuse the hot air from the card.
