In cases where your car won't engage the starter at all AND the engine fan warps up to high speed, it is usually a case of a failed "Engine Control Relay" output from the RCM.
In cases where the car runs fine, but the fan runs very fast, the RCM is not implicated at all. I must disagree with the advice about changing the RCM.
ONE MORE NOTE:
Putting so many issues from more than one car in one thread will not get you help as well as creating two threads: One for each car.
