Electric fan options well suited to 2.9's

I've been scrolling through some old posts on here, and I'm really close to putting an electric fan in my truck. The tech article with the Volvo fan appeals to me, cause I really like the Volvo relay and it's two speed capability. But! I don't like how much surface area is taken up by shroud... Like almost a third! That scares me with a 2.9.
Which is why I'm liking the twin "pusher" fan from a Mercedes that @PetroleumJunkie412 mentioned in a few posts.
Would it be possible to run that Mercedes unit on a Volvo relay? Does the Mercedes one have it's own relay unit that doesn't rely on it's ecu to function?

Seriously just two fans with two wires each. Any type of thermostatic relay is possible, and you can control them as two separate units.

Sweet! I'm guessing I could pig tail them together, and run them off the same unit...
What year and model was the twin fan unit from?

C230 Kompressor. Think they were built 1998-2003
