4028 Part cooling Fan is not controlled correctly
Hey guys,
I tried my best to figure out what´s the problem but this is the first real self builded printer for me and I don´t get it.
I´ve connected the part cooler like the manuel did tell me. +/- on the permanent fan header on the BTT Octopus 1.1 and the blue wire on the - of the other fan port on the board. But actually my fan spins 100% when I set it to 0% in the Dashboard and 0% fan when 100% on the Dash.
How can i fix this inverted reaction.
Thanks a lot.

4028 server fans are becoming a popular option for part cooling because of their light weight and great pressure and flow rates. In this guide we'll go over how to connect one and use it for part cooling. 4-pin fans usually aren't used in 3d printers, and many boards only provide 2-pin ports, but fear not! There's always a way.
