I doubt the difference in height from the top to the bottom of the PSU leads to much of a differential in pressure. Since the top case fan is probably more than adequate removing hot air from the top of the case, the PSU fan is probably functioning primarily to cool the PSU. In this case, convection is probably helping the process.
