There is already a thread about this, but it is around 10 months old and I thought it would be beneficial to create a new thread with a more specific focus.
Anyway, setting all that aside, I think I will open up the back panel of the printer to see if there is enough space after printing out an outline of the 120x120mm footprint. One thing though, I believe the NF-F12 iPPC 24V 3000 PWM has a lower max RPM than the stock chamber exhaust fan, so I’m not sure how the PWM signal will respond to the slower tach signal.
Hopefully I can get some research done this afternoon.
