They improved the cooling system but why there is still one fan setup.Dual fan setup -> much more less noise and more cooling.I didn’t test it OLED model yet but currently old steam deck is not usable at 15W because of noise.
People are using at 10W mode, little performance loss and noise down to acceptable level.I hope we don’t have to do this in new OLED model.
I use Honeywell PTM7950 and the new ysaux vented backplate and I don’t have noise at 15w it still keeps cool and quiet.
