When my after-run system kicks in (usually requires parking after engine
has been hot enough to make the fan come on while running, AND continued
under-hood heat in an environment like the 94 + degrees F here today), you
can hear the fan from several car lengths away.  I always assumed this was
"hi" speed.  Today, I heard it come on twice after I had shut the car
down.  I didn't note the length of time between "on" cycles, but it was
like 10-15 minutes between the two times I heard the fan.  Usually, the fan
runs for a minute or two in the after-run mode.
