Man of Honour
No only the early gen QD-OLED panels are as they have 1 or 2 fans depending on variant (Gsync Ultimate models have their own fan for the GSYNC module and the QD-OLED panel then has a fan too) . Even the 1 fan version (AW3423DW) has an audible fan. It's not distracting, it's just //there// if that makes sense which is obvious in a completely silent room with a completely silent PC but I learned to kind of ignore it though now I'm in total silence again.Are all ultrawides noisy? I had my eye on one for a while now.
Other brands like MSI/Asus etc use different methods on their panels like a custom heatsink. The current 3rd gen QD-OLED models don't seem to have any noise, even though they have a single fan.
