Cooling fans were first used and primarily intended for Touring Cars and Buggy's, whose aerodynamics and/or body design inhibits any air getting to the electronics.
So keep in mind that a cooling fan in your case is really just a quick-fix, that in many cases if you're running that hot to use a fan to keep it running you're really just applying a band-aid. Optimally, an ESC/motor should be able to operate just fine without an excessive cooling measures.
