Fan sound

The cooling fan on my @002 S Jaguar stays on for about 1 to 3 minutes after I turn off the motor. We also hear it while we are driving. Two dealers say it is normal and 2 dealers say bring it in for a check. An excellent mechanic scoped it out and stated it is fine. Whom do I trust?

The two dealers who said it is normal and the mechanic who stated it was fine.

The fan runs when it needs to run, whether the engine is running or not. Sounds normal to me.
