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.
The APU is on a 6nm node instead of 7nm. It’s more efficient at the same performance level: less power, less heat. They’ve also pretty dramatically changed the layout of the internals in the OLED model, and it has better airflow now, as a result. That’s why.
