UDM Better Fan Speeds

Github Repository: UDM Better Fan Speeds

What It Does

It stops the build in service that monitors the thermal values, fan speed and connection of a HDD/SSD. After that it sets the thermal/fan chip (adt7475) to automatic mode. Once that is done it changes the thermal and fan threshold values specified in the script. If you like, you can change the values to your own preferences.
