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 watched bunch of reviews of the oled version (probably tad too many, but hey, hype). some reviewers tested temps and noise. they all said: it’s running cooler (oled less demanding than lcd; bigger/better fan) and quieter under load. noticeably.
they also said (few of them actually) they have never before seen a revision like this, in a positive way. compared to what nintendo did with switch (screen only really) and ps with ps5 slim now, valve is praised for the amount of work they put into this. the list of upgrades is really something if you go through it.
my bet is valve improved fan, tested with new screen and all and said ‘yes, this is good now, improved a lot’
