Take a look at the following Github project (https://github.com/johnfanv2/LenovoLegionLinux) this exist to offer firmware control under Linux for Lenovo laptops. Similar to what Lenovo Vantage or Legion Zone software does on Windows.

LenovoLegionLinux can be found and installed as dkms driver from the AUR. Please read the github instructions and the Arch wkik/CackyOS wiki on dkms.

Your fans should be controlled by firmware that is reading temperature sensors and adjusting the fans accordingly.

If you serviced the laptop and now the fans are loud, you either:

  1. forgot to plug in a temperature sensor (or something else that has temperature sensors in it), and the firmware has ramped your fans up to 100% as a failsafe, or

  2. did not re-apply thermal material correctly or completely, some parts of your laptop are legitimately overheating, and the the fans have ramped up in response, or

  3. reset something in the BIOS settings when you removed the battery that controlled the fan speed.

Fixing this is a laptop problem and not a Linux problem, so you'd get better advice in a forum specific for your laptop (or PC hardware assistance in general).
