I had thought about it, hadn't figured out an answer (yet).
The fans I see used in these are slimline sealed units with electrical wires run through a bung in the back/bottom of the duct after the radiator. I haven't looked too hard into their ability to survive rain/weather... I had initially wondered/worried about snow and foreign objects. As far as water pooling up, if you tilted your radiator just a smidge to the front, the water could drain out into the front ducting and maintain a relatively small puddle that I assume would be ejected the minute you got some air coming through the duct. But if I'm not mistaken, some land speed guys set their core in a box of water to assist with cooling in the absence of appropriate airflow... Of course I'm sure these aren't your average radiators and inter-coolers though!
Just add this to the list of things to figure out
