Question about be quiet! Pure Base 500 FX

Are the three included front panel fans airflow or static pressure? I was thinking about potentially buying "be quiet! Pure Loop 360 Liquid CPU Cooler" and using it as frontal intake by taking case fans and putting them onto the radiator since the ones which come with the radiator are not rgb. (Putting a smaller AIO for CPU on top is not an option since I already have my GPU AIO there).
