Any opinions whether the cooling would be more effective with the flow

This is a classic example where testing trumps theory. All the things
you said about convection, the hood being hot, etc. are true. But they
may be "feathers on the scale" that have an insignificant effect. And
there are other "feathers" that come into it as well (wind blowing
around under the hood, fans that lose performance if their intake side
is restricted, etc).
Put a thermometer of some kind on the heaksink, and try it both ways.
Position the fans to provide the lowest temperature.
