A turbine airfoil (12) includes pressure and suction sidewalls (18,20) extending in chord between leading and trailing edges (22,24) and in span between a root (26) a nd a tip (28). A septum (30) is spaced between the sidewalls to define two cooling circuits (32,34) on opposite sides of the septum which converge between the leading a nd trailing edges. An array of pins (44,46) extends inwardly from the pressure sidewall (18) at a discharge end of the circuits, and the pins decrease in length to conform wi th the converging circuit.
