Simulating pin-fin heat sink?

I’m looking for a way to simulate a pin-fin heat sink in Flow Simulation, but the only thing I see is for the integral fan-cooled heat sinks.  My application is force-air cooled, but the fan isn't mounted to the heat sink itself.  I can define a heat sink in the database using curves for pressure drop and thermal resistance, but I can’t see how to include it in a model without selecting a fan?  Is there a compact way of including this heat sink performance without actually modeling the pins?

Thanks!
