The advantage of an electric fan is that you are no longer dependent on engine RPM, for example, stopped in traffic when you need the most air flow, the mechanical fan is not very effective.

Also, above about 4000 RPM, the mechanical fan is disengaged to protect it, no need to do that with an electric, although at 4000 RPM the car is probably going fast enough to not need any help from the fan. On a W124 MB, after about 25 mph, no fans are needed.

With two electric fans, one or both can be turned on as needed.

But in an MB, you will probably have to upgrade the alternator as well. Do a search and you will finds some discussions on this topic.
