Yes, I think that is exactly the problem. Looks like the board uses a multiplexer
to connect multiple fans to the same fan sensor input. Which makes it all but impossible
for third parties (like Linux) to implement working fan control. Really annoying,
especially since the NCT6776F has really a lot of fan sensor inputs available.
At least some of the other boards from the same vendor have lots of fan connectors.
Did you try all of them ?
