Normal
A few years ago it was pretty common for people to remove the heatsink/shroud/fan from their video cards in the NCASE and either use the Accelero3 or Morpheus2 cooler with Noctua fans. Most people that did this found that having the two 120mm fans as exhaust lead to better temperatures. I'm currently running a Vega56 with Morpheus2 and 120x15mm Noctua fans in this exhaust configuration with good results, but I did not do extensive testing. It is CERTAINLY quieter and better performing than the stock blower heatsink and fan combination that came with the card.
