Maybe we are just confusing the semantics. Fan clutch and clutched fan mean two different things to me.
The fan clutch is the center section that provides the variable connection between the actual fan and the belt driven wp.
If you say the clutched fan explodes, yes, if the fan blades hit something they will probably shatter. The clutched fan assumes the whole assmebly.
Understand that there are two completely sepeate parts being discussed. The actual clutch and the seperate fan blades/hub. Together they could be properly referred to as the clutched fan, or engine driven fan, as opposed to and autonomous electric unit.
Fan clutches though, do not explode.
