Fan Not Working Properly under high temps on Linux (Swift SFG14-73), No control, Need BIOS/EC update

Hello, I am using an Acer Swift SFG14-73 with BIOS version V1.13. While the fan works correctly in Windows, it does not spin up under high temperatures when I use Linux (Fedora 42). I’ve tested this by running CPU stress tools — temperatures exceed 100°C, but the fan remains silent, suggesting it is not controlled properly by the firmware under Linux. Fan control interfaces are not exposed to the OS, and no PWM sensors or control modules are available. I would like to know if there's a firmware or EC (Embedded Controller) update available to improve fan compatibility with Linux or allow BIOS-level fan configuration. Thank you.

    Hi, no Acer BIOS updates yet but have you considered these third-party tools:
    CoolerControl: A Linux tool that provides a GUI for monitoring system sensors and creating custom fan profiles.
    Fancontrol (lm-sensors): A command-line tool that allows manual fan speed adjustments, though it may require additional configuration.

    It's unlikely Acer will do a BIOS update to support Linux issues, since they don't ship any of those models that I know of with Linux pre-installed. Since the BIOS control of the fan is OS independent, your issue is more likely with the kernel. It often takes the Linux developers about a year to fully support new system designs, and your SFG14-73 is only about six months post release. The chipset itself though is just over a year old, so I would have thought they would have the fan control handled by now.
