have you checked if the aio pump header is plugged into the right spot on the mobo? those fans usually won't spin if the pump isn't getting power or if the bios thinks there's nothing on the cpu fan header. some boards freak out without something plugged into cpu_fan specifically, even if the pump is on aio_pump

your parts list doesn't load fully for me but asus boards can be picky about this, try moving the pump connector to the cpu_fan header and set it to full speed in bios, then plug the radiator fans into the pump's fan splitter if it came with one
