An airfoil includes a multi-part body and one or more thermally conductive pins. The multi-part body has an interior region and is formed from multiple pieces joined with each other at an interface. The pieces have multiple cavities and at least one of the pieces defines airfoil cooling channels disposed within the interior region of the body. The one or more thermally conductive pins are within the interior region of the body and extend across the interface. Each of the thermally conductive pins has a first segment disposed within a corresponding cavity of a first piece of the multiple pieces and a second segment disposed within a corresponding cavity of a second piece of the multiple pieces.
