The library reference you quote: "tach signal

" is not a "DC signal"... any more than it is a "tach voltage"
DC = direct current = a continuous electric current flowing in one direction.
Signal = a function that conveys information
We can have DC powered signals... but that is not a DC signal.
There is no "DC signal" going to the Phanteks hub from your MoBo fan header.. It is DC voltage. There is a tach signal coming from fan motor to your MoBo fan header.. it is not a DC signal.
Tach signal is tach receiving a signal
DC signal is not direct current receiving a signal.
Direct current / signal has no similarity to "engine / motor" or "potato / potahto, tomato / tomahto, pyjamas / pyjahmas".
As I see it you made a simple mistake when you wrote:
"I am running 10 DC fans off the Phanteks Fan Hub with one DC signal
from the MoBo."
I think you were saying that you are powering 10 fans with DC voltage
on the Phanteks fan hub supplied from your motherboard fan hub.
That is what I have been trying to find out.. and if you are able to adjust the fan speed using variable voltage control from MoBo header.
