Power the Hubby via the PSU, and set the control mode to PWM, and you'll have no issues running 1 full rad's worth, (8) per channel, and there'll be virtually no load on the A6.

Thanks for your input everyone, much appreciated! I have actually considered doing just that, powering the splittys/fans directly from the power supply, and just using the Aquaeros for control.

I am going to shorten the current pigtails on each fan, and change the sleeving. My plan is to make a custom fan wire harness for each channel, and not use any splittys. I would like to keep the fan wiring as clean as possible. With custom fan harnesses I'd just have one cable for each channel plugged into the Aquaero, and less wiring clutter. I have eight channels available, so I have enough channels to pull it off.

Here's how:
Channel 1 - Left top and front push fans - 6 fans
Channel 2 - Right top and front push fans - 6 fans
Channel 3 - Left top and front pull fans - 5 fans
Channel 4 - Right top and front pull fans - 5 fans
Channel 5 - Left bottom fans - 4 fans
Channel 6 - Right bottom fans - 4 fans
Channel 7- HDD cage fan and rear fan - 2 fans
Channel 8 - reserved for a something I haven't shown yet

The EK 140ERs are 2.3 watts each, and the EK 120ERs are 2.16 watts each. So that would have 50.6 watts on the Aquaero XT and 22.7 watts on the Aquaero LT. The Aquaeros are rated for 30 watts per channel, so they should be able to handle that. I could also rearrange the channels to even out the power distribution more evenly between the two Aquaeros.

I do have four splittys if I decide to power the fans from the power supply. The only really good place I have to put the spittys is under the top cover, or mounted to the back/center divider next to the Aquaeros where there is not going to be a lot of room. If I go this route I'll make custom length fan extension cables to go from the fans to the splittys.

Here's how I could set up the channels then:
Channel 1 - Top push fans - 8 fans
Channel 2 - Top pull fans - 6 fans
Channel 3 - Front push and pull fans - 8 fans
Channel 4 - Bottom fans - 8 fans
Channel 5 - HDD cage fan
Channel 6 - Rear fan
Channel 7 - reserved
Channel 8 - extra

Once I get the all the fans and radiators mounted up again I'll figure out which way to go.
