I've heard that the water pump impeller can come loose from the 
shaft, causing overheating.  Another more common problem is to 
replace the thermostat.  If the fan belt that turns the water pump is 
too loose it could overheat (I don't know if you have a/c or power 
steering).  The radiator could have a blockage.  A real unusual thing 
could be a over-soft radiator (upper or lower) hose collapsing and 
cutting off water circulation.

That should give you enuff ideas and hopefully lead you to a 
solution.  As far as the fan only running after the motor's off, it 
could be that the sensor is faulty and needs replacing.  It should 
come on before the engine overheats, not after.  You may want to get 
a low temp switch so it turns on quicker.  If you have a/c, you 
could turn it on when it starts getting hot and that will make the 
fan run.  Not a solution, but a way to get thru till you find the 
real problem.  HTH
