Snapmaker J1 "s" upgrade Control the fan help

Hello! Could someone please help with the control of the print cooling fan? I’m using Prusaslicer. Jade’s post (Snapmaker J1 Print Cooling Fan Upgrade Kit & J1s Model - #17 by Jade) mentions using the Dynamic Fan Speeds (Overhang) but I’m not clear how to use these settings. Any help would be appreciated. :slight_smile:

Do you mean this?
