Summary0002059: Maximus V Formula mobo only handles 4 of 8 fans
DescriptionOn my Asus a, there are 8 fan headers.

Speedfan sees 5 of them, and can control 4 of the 5.

It finds a Nuvoton NCT6779D at $290 on ISA, with 5 fans and 2 temps.

Fan control on 4 of the 5 seen by Speedfan is good... smooth and can stop them.

The 5th does not report speeds from any of the 8 fan headers on the mobo.
