Does the cooler need direct air flow? I ask given I still have not decided where to place the cooler. How about a fan?
An electric fan is just another point of failure on what is, presumably, a critical component (they put that oil cooler on for a reason, right?).
Using a fan opens up a Pandora's box of related concerns to manage... thermostat(s), relay(s), fuse(s), wiring and connectors, fan reliability, fan redundancy, fan operational monitoring, cost...
I would not use electric fan in this application unless there was absolutely no other way to get the job done w/o it.
Making it work is one thing. Making it suitable for mission-critical work is a whole different ballgame.
