Hi guys! I have managed to finish a golden build on a tricky laptop, and I’m very satisfied with the result as I’m running nearly vanilla and everything is working veeeeery good and fast.


I am unable to tweak fan speeds via DSDT, I see there are some devices in it related to temperature control but I am not able to reverse-engineer them.


I’m attaching here my DSDT, would someone be so kind to have a quick look and point me in the right direction?


Is maybe fan speed controlled by a microcontroller? I’ve read something once, about talking to the microcontroller via DSDT.


Thank you so much.  :)
