An integral ceramic casting core includes a base portion with a plurality of rods extending therefrom and a plurality of apertures formed therein. The base portion defines a passageway for the passage of a cooling media within a cast component. The plurality of rods forming cooling media inlet passages to the passageway and the plurality of apertures are adapted to receive molten metal therein and form heat transfer pedestals within the passageway.
