Cooling fan sometimes wont cut off?
With many cars now days, the fan may continue to run after the car is shut off, or they may even start and run for a while after the car is shut off. An engine will actually get hotter for a short time after being shut off. Sometimes that will trigger a sensor to turn on the cooling fan. If it continually runs after being shut off, it could be a faulty temperature sensor, or a faulty fan relay, or even a bad computer.
Why would an electric motor on a 1986 300ZX keep going after the car is turned off?
the Fan motor will keep running fort a short time after the car is shut off. the motor actually gets hotter after it is shut off so the fan cools it for a few minutes before cutting off. Actually, on all the mid 80s 300zx engines, there is a fuel injector cooling fan that directs cooling air on the injectors for a specific amount of time after the car has been run at normal operating temps and then shut off. Is your car a turbo z? If so then the fan that comes on is the fan that cools off the turbo after the key is shut off. Maybe you have an aftermarket fan set up for the air conditioner, but there again they usually come on while idling with the air on, but they generally shut off when the key is turned off. The fan is not used for cooling the turbocharger. The turbocharger itself is watercooled and does not have a need for a fan. The electric fan is for cooling the fuel injectors as mentioned in the previous post.
Why does your fan motor run after the key is shut off?
The engine cooling fan will continue to run because the engine is hot. Once the engine has cooled down the fan will shut off. If it never shuts off you may have a bad temp switch or relay.

The fan is on a thermostat, causing the fan to run if cooling is required, even when the car ignition is turned off. Having said that, if you notice that the fan is running long after you've shut the engine off, you may have a problem!

No. The fan should shut off when the engine temp is to cold for the fan to be on. If its on all the time the temperature switch/sensor is probably defective.
