W126 - Dual aux fans versus Single?
I've seen very late model W126s have dual aux fans up front. Would there be any advantage to pick up two sets to stick on my SDL and the SD?
They appear to have more AC condensor coverage than the single and from a quick observation have the single harness back to the Aux Fan Switch by the AC condensor. My cars are both R12 if that makes a difference. Thanks!

In 1990 MB started improving their A/C systems in prep for the up-comming R134a refrigerant. THAT was one of the best ways that they could get better cooling at idle!

Hrm, I guess it can't hurt a thing!
Do you happen to know if the fan switch changed for when they went to dual fans? Making the aux fans come on sooner (temp wise) or the AC high side pressure switch change Thanks
