Question Dual AIO (gpu and cpu) setup question

[lorddaroth]

Hello

I was hoping you guys could help me determine if this setup could work without problems.

I use a 240mm AIO cooler for the CPU, and I wanna use a 120mm one with the Kraken bracket for the GPU to push it further.
I would like to know if the connections and header setup could work in theory:

The two pump (and pumps only, no fans) would be powered from the motherboards aio header via a splitter. These would be run on the same speed all the time, lets say a constant 70% or something.

The two fans would be powered and regulated via the mobos cpu fan header.

And the 120mm and 92mm fan for the GPU would be run from the GPU fan input.

This way both the cpu and gpu cooling would be regulated based on their respective temps. I wonder, is there any errors or cons to this setup? Am I missing anything or this could work in theory?

It's not a good idea to run two dissimilar motors (in this case pumps) of one header even if you don't want/need to control speed as even reported RPM would not be accurate. You can't control their speeds independently anyway.
Same goes for fans plus CPU fan has to be controlled by CPU temps and GPU one by GPU temps.
