A Steam Deck software update significantly reduces fan noise

Valve’s latest SteamOS update is big for Steam Deck fans – and I’m literally talking about the portable gaming PC fan. A common complaint about the Steam Deck is its sometimes loud, high-pitched fan whine, even when playing light games. Some, including my colleague Sean Hollister, have tried a DIY fix to fix the whine, and iFixit’s Steam Deck replacement fans are already sold out despite having been on sale for less than a week.

With SteamOS 3.2, however, Valve introduced a new OS-controlled fan curve that aims to improve things. “That means overall it’s smarter, more responsive to what’s happening on and inside Steam Deck, and quieter — especially in low-use situations,” the company said in a blog post (emphasis added by Valve).

To see if I could notice a difference, I installed the update on my Steam Deck and tried out a few games. In my short and extremely unscientific tests, I feel like Valve has made some big improvements.

I first started Rogue Legacy 2, a side-scrolling roguelike that isn’t too graphically intensive. I immediately noticed that the fan was dramatically quieter – I could only hear it sporadically – and with the speakers on I couldn’t hear the fan at all. I had a similar experience with vampire survivorsalthough I haven’t had time to get to a typical endgame, where the whole screen is filled with enemies and weapons – I’m curious to see if this will push the fan further.

In Sekiro: Shadows Die Twice at settings pushed to the max, the fan is still audible, although it’s generally much quieter compared to the old fan behavior, which you can revert to in the settings menu if you wish. With the new update installed, I also didn’t hear the fan idling on the Steam Deck menu screen, which was one of my biggest pet peeves with the device.

SteamOS 3.2 also lets you change game framerates on the fly right from the three-dot menu button. “The default is 60Hz (which can be limited to 60, 30, and 15fps), but now you can drag it up to 40Hz (with frame limits at 40, 20, and 10fps)” , says Valve. Reducing the refresh rate is a lever you can pull if you want to improve battery life.
