Setting Fancurve on Thinkpad T480

Hey guys,

I have a Thinkpad T480 running Sonoma with Opencore and the YogaSMC.kext. Now YogaSMC displays the fan speed and I can manually adjust whether the fan should spin faster or slower. Unfortunately however, it doesn't seem to work with the apps I tested which can set a fancurve depending on the temperature and inside the app I couldn't find anything to set this curve. Now on occasion the T480 gets really hot (80+ degrees Celsius) and it's cumbersome to manually adjust the fan speed. Is there a way to set a fan curve either via YogaSMC or third party apps?
