I just noticed the Envoy uses a clutch fan, what were they thinking?

Anyhow, this system will totally replace the clutch fan system?
What means is it using to know the engine needs more cooling, aka where are the sensors going etc etc....

I really want to get the clutch fan off this engine and go to fans.
