I'm no fluid dynamicist or whatever, but it seems that because air moves from a higher pressure area to a lower pressure area, it depends on whether the pressure is higher above the coolers or below them. Once that is determined, run the fans in the direction that will enhance airflow through the coolers.

One way to assure the pressure is lower under the coolers would be to use an air dam of some sort. This would tend to rob the intercooler and radiator of some flow, but I seriously doubt an air dam would be so efficient that it would cause them to be starved for flow, especially if thought was given to the size and shape of it.
