Every fan controller and MB header is only capable of measuring one fan per series string. It measure "pulses per unit of time", so adding more pulses to that wire would screw up the signal and you get weird readings. There is no way to really fix that other than get more channels or make sure all the fans on that one channel are the same so you assume they are all about that one RPM.
Gotcha. Thanks!
