The only disadvantage,
With the LL fans you could connect 2 channels with 2 controllers to one USB on the mainboard,
Now I need an extra USB on the mainboard for 7 fans. Do I see that right? And if so, what were they thinking?

Accepted Answer

I am running 9 QL fans on a mainboard USB... 

The prerequisite is that you either: 
- Corsair Commander Pro (you have to connect all the fans somewhere).
  -> I use 2 Commander Pro and 2 Lightning Node Pro to be able to address each of the 9 fans and 5 LED strips individually. You can connect the Commander Pros "in series" and the Lightning Nodes Core and LED strips to the LED connections of the Commander Pro. I have everything on 1 USB header of the mainboard. Works perfectly.

or alternatively: 
- PWM and RGB splitter cable, then they run on the same channel.
