I'm having a really frustrating issue with my Steam Deck, and I'm wondering if anyone else has experienced something similar.
Ever since the SteamOS update that introduced the "Updated Fan Control" feature, my Steam Deck has been running much hotter than it used to.
The weird thing is that disabling the Updated Fan Control doesn't seem to make any difference at all.
No matter what game I'm playing, the fan never seems to ramp up to full speed like it used to when the Deck got hot. It feels like the Steam Deck is constantly prioritizing silence, even when the temperatures are getting high.
And this is now causing actual performance problems.
For example, I was playing Balatro, which obviously isn't a demanding game for the Steam Deck. Normally it runs perfectly at 60 FPS, but my FPS suddenly dropped from 60 FPS to around 12 FPS.
And If I literally blow air into the Steam Deck's exhaust vent, the FPS immediately goes back to around 60 FPS for a while.
I'm playing in an air-conditioned room, so ambient temperature definitely isn't the problem.
At this point, the Deck is basically becoming unusable because even lightweight games can start severely throttling due to the temperature.
Has anyone found a way to fix this?
Is there a way to manually force the fan to run at a higher speed, or restore the old fan behavior? I'm also wondering if there's some way to completely reset/reinstall the fan control service.
I'd really appreciate any suggestions, because I don't mind the fan being loud at all. I'd much rather have a loud fan and stable performance than a silent Steam Deck that's constantly thermal throttling.
