Of course a lot of that comes from how efficiently (cool) my diesel runs.

Yes your fan clutch operates different than most gasoline engines. While yours produces almost no drag while not in use mine does. My fan still moves at water pump rpm whether the clutch is engaged or not.
I do agree with you that on your platform a electric fan would be a waste, although on my platform and every other temp driven fan clutch out there a electric fan and shroud is the way to go. Or if a electric fan isnt possible adapting a viscous fan will still be better than a standard run of the mill fan clutch.
