Sorry, I just checked it again. I had a little mistake with your PCB number. The cooler I displayed fits for:
PowerColor Radeon RX 6800 Red Devil, 16GB GDDR6, HDMI, 3x DP (AXRX 6800 16GBD6-3DHE/OC)
However, I would not rule it out completely. Could you send us a photo of your PCB? It could be possible that the cooler fits - but we simply don't have your card type in our database yet.
