Wierd ARGB/Fan Hub issue
Got 2 of these ARGB/Fan Hubs and have encountered a strange problem:
I don't use the ARGB cable, just use the remote. That part works fine.
Both fan hubs work fine in two PCs but neither of them will control fan speed in one other PC. The fans always run at full speed in it, as though the PWM is not connected. In the PCs that the hubs work in, disconnecting the motherboard fan plug make the fans run full speed. The ASUS M5A97 R2.0 motherboard has 4 X 4pin fan ports and the fan hub doesn't control fan speed in any of them, RPM is displayed in SpeedFan app though, it reads the speed of the fan that's plugged in to the red fan jack.
Every one of those 4 ports controls fan speed and displays RPM when I plug fans directly in to them.
The 4 pin fan plug from the hub only has 2 wires connected, PWM and RPM, there is no power or ground connection.
Should be a plug it in and it works deal, it is on two PCs but not the third. Anyone ever seen an oddball problem like this?

Thanks admin, for moving this, wasn't sure where it belonged.
