An oil cooler is always a good idea. Unknown to most your highest oil temperatures are at Interstate speeds when the most air is blowing through the oil cooler
It's it's why just about every brand bike out there that it's rare a fan is ever on a oil cooler.
The only help a fan would do is if you were stuck in traffic and were concerned about your oil temperature but lowering your oil temperature is not going to cool your engine so if you were concerned about the engine overheating an engine fan would be best.
On on the Rushmore bikes 2014 and later I know for a fact the bottom of the Pistons are sprayed with oil at high speeds and that is why the high oil temperatures at high speeds and why Harley-Davidson included oil coolers on these bikes.
Once you slow down to slow-moving roads your oil temperatures drop even though there's less air going through the oil cooler.
I have intensely followed my oil temperature for the last 2 years on my 14 Road King and know for fact oil temperatures run 252 265 degrees 2 up, 90+ degree weather at 80 miles per hour and I have a 10 row jagg oil cooler on my bike which I swapped out from the 6 row Harley-Davidson
Once off the interstate oil temperature drops rapidly because the Pistons are not being sprayed anymore the only time temperature will rise to what they are on the highway is at if you're stuck in traffic, at that point though an engine fan would be better for traffic because oil is not going to cool your engine.
True there is nothing wrong with having a fan on an oil cooler but if you want to have a fan the best choice at that point would be an engine fan.
I don't know the behavior of the pre Rushmore bikes as far as if the Pistons are sprayed to cool them down but if you're looking for a fun project for me personally I would go for it.

Oil coolers and head fans have been discussed a lot on Harley tech talk. There have been a few comparisons and some testing between both methods. In every circumstance, the head fans cooled the oil more than the oil coolers. It was also found the fans used, Love Jugs Mighty Mites, will have some sort of cooling effect up to 50mph. Speeds over 50mph, heat shouldnt be a problem anyways unless something is wrong with the bike.
I have a pretty good defense against heat. Baker +1.5qt oil pan, stock oil cooler, and Mighty Mite head fans. Even at 11.1 to 1 compression, my EITMS does not kick on at stop lights and in slow construction traffic. When my bike was at stage 1, I could count on it kicking down to 1 cylinder quickly even at stock compression. A friend of mine with a similar build but in a 124 configuration does not see over 210-degree oil temps since installing the fans. My bike is a Road King so I cant see oil temps on a dash. I didnt care for the looks of the fans, so painted them granite to match the motor. Now I dont even notice them anymore. What I love, is that they also cool the heads, not just the oil. Some dont realize head temps and oil temps are two separate things.
I purchased an Oil Bud oil cooler a few weeks ago and had to send back because of a fitment issue. It may have been a blessing in disguise as I dont think it was really needed with my current setup. Those little fans are kicking ***.
