I have a Ender 3 Pro and I just installed a new SKR Mini E3 V3.0 as I fried my other board cleaning filament off the hotend with a wire brush. I noticed that the fan for the hotend only comes on at around 50C. I am using Marlin 2.1.x bugfix. Is there a way to have the hotend fan turn on sooner like at 30C or 40C?
