TT has made things easy. They took a step back and went with a molex connector that uses both 5v and 12v instead of Sata like almost everyone else. The best part of that is the power ability of molex far exceeds Sata.
The software itself is capable of handling upto 80 fans, 16 boxes with 5 of the riing fans each. Because they are ARGB, not RGB. Important distinction. With ARGB, there's 1 addressable controller chip that sends power through the 3 color diodes in varying amounts, so all that's needed is power + signal, in affect a pwm fan, power source isn't a worry, just the signal source . With RGB, there's no controller chip, the motherboard sends the power through the diodes, vary the power, varies the color. In affect a DC fan, power is limited to the header.
So the molex supplies the 5v, the software supplies the signal. The 12v comes into play with regular fan control, same as any other pwm hub. There's switches on the box so you can set whichever you want to control, the exact settings will be included with the directions.
Basically, you setup 1 box per header, in whichever series you want, can be 5-1, 4-2 or 3-3 depending on how you want to set the fans up. With 3x intakes and 3x exhaust, that's 1 box for each etc.
The individual fans and lighting all going back to 1 program where each is addressed and addressable. Plug and play.
Being like pwm fans on a powered splitter, the 72 led limits of the header don't apply, might as well be just a single led, the signal being the only factor, which is nothing more than a series of addresses. The only time that limit would apply is for fans lighting hooked directly to the header be it a fan or strip (exactly the same thing, different shape) through an unpowered splitter.
