But there's the rub: it has to be available, and I doubt fan speed is. There'd have to be some sort of sensor on the fan. I've never seen that.

I believe my truck does have a fan speed sensor. I found some info over at the Cummins forum where somebody posted the diagnotic procedure to check and see if the clutch is working properly and it involves the technician hooking up a diagnistic tool and reading the fan speed and different engine rpms, so I take it it is and OBD II parameter.
