Sorry for the confusion. I think I figured it out.
So I have a bunch of Lian-Li unifans connected to their USB hub. This USB hub is connected to the motherboard sysfan 3 connector.
However, the cable that connects is only a single wire to the PWM pin, so it is not reporting a fan speed and thus HWiNFO isn't showing the sensor.
So only question I would have is, is it possible to get readings from the Lian Li fan hub like it is able to get readings from the Kraken?
