The D5NEXT is not a simple PWM pump, it has its own control including water temperature sensor, virtual flow sensor, fan control for PWM fans and RGBpx control. It connects to the motherboard via USB and to the power supply via SATA connector.
The control of the pump speed and the fans via the Aquaero is additionally possible via an Aquabus cable, but not necessary.
Whether it makes sense to have two different D5 in the system I can not say, I get along with one very well :-)
