SteamOS 3.2 update adds refresh rate settings, quieter fan curve to the Steam Deck
Got a Steam Deck? Lucky you. Anyway, if you haven’t already, you should install the SteamOS 3.2 update that just released, which quiets down the noisy fan and gives you more options to extend battery life along with other improvements.
With version 3.2 the Steam Deck can be switched from the default 60Hz display refresh rate to 40Hz. Then you can set a frame limiter, typically to something like 40, 20 or even 10fps. These settings are per-game so you can keep action-packed games at 60fps, but limit puzzlers to something lower that won’t impact gameplay much.
Here’s an interesting note...
