There is a bug in the upstream driver affecting the number of fans
detected for NCT6776F. You can try a possible fix by loading and
installing the driver from
https://github.com/groeck/w83627ehf/archives/testing.
No idea if that helps, though. The bug has always been there, so I have
no explanation why it might have worked with archlinux 3.0 LTS.
