Are you looking for hardware support?

Octopus Pro v1.1 STM32H723ZE
4 Fans for Electronic Box
1 Fan for Part Cooling

Describe the feature you want

Marlin only gives us the option to define 2 controller fans in the Controller Fan section under the Configuration_Adv.h
Octopus Boards and other BTT large boards can support up to 6 cnc fans and it would be nice to take advantage of those fans.

In my case, I have 4 Fans in the electronics box. But marlin only gives me the option to define 2.
