I want to buy the CM MF120R 3-in-1 pack of fans for my radiator -- Thermaltake Water 3.0 Ultimate. I also want to buy three MF140R fans for the rest of my case. I could buy a second pack of 3-in-1 fans but 120s look a bit small in my Carbide 740 Air.

My MOBO -- Strix Z370F -- has only one ARGB header.

Is it possible to connect all six fans to the ARGB header "out of the box" ? What extra stuff might I have to buy?

Does the 3-in-1 pack come with a 3-to-1 PWM splitter so I can connect all three to the CPU Fan header?

Does anyone recommend the XSPC 8-way ARGB hub? Or ANTEC's ARGB fans and controllers?
