Is the AIO pump PWM controlled? Is the fan PWM controlled? If the pump and fan are both PWM controlled you need to buy a Gelid VGA PWM adapter and a PWM fan splitter w/ molex power source so you can plug the pump and fan into the video card. If the fan is not PWM it is probably best to buy one that is or plug the fan into a 3-pin to molex adapter. If the PUMP is not PWM it is probably best to plug it into a 3-pin to molex adapter.
The motherboard has no clue what temp the video card is at so you should either run everything at 100% or buy the proper parts to run the fan or the fan and pump from the video cards fan controller.PWM FAN ADAPTORPWM Splitter that gets the 12v from molex (doesn't use power from graphics card).PWM Splitter that does not supply power from molex.
It is likely that you card would be perfectly fine running an AIO PWM pump and fan from it's own power source but it is always best to play it safe so the 3-way PWM splitter that has the molex plug on it is the best way to ensure you don't damage the video card in any way. It also can handle 3 devices so if you decide to go push pull it can run both fans and the pump (if the fans and pump are PWM).
Also if you are going to run off the cards PWM controller it is best to build a custom fan profile that enabled 100% fan speed at a much lower temperature (45-55C) and it is usually best to have a fan that gets some airflow over the card so that the cards VRM heatsink doesn't get too hot so either a fan that is in the case panel that is directing air over the card or a fan directly over the VRM or a fan blowing from the end of the card (right side) towards the beginning of the card (left side). If that fan is PWM it can be connect to the PWM splitter so that the speed is controlled by the video card. If it isn't PWM it is best to find a constant speed for it to run at all times.
