Once the computer commands the fan on, will it ever shut it off? At what temp would it do so?
 
Computer fan temp depends on what is programmed in the chip. The fans are also controlled by a fan delay relay that often fails allowing fans to operate even when car is not running. There is also a switch on the intake manifold that will turn the fans on if the temp is over 200+ degrees that will sometimes go bad causing fans to run constantly.

Not chasing down a problem, just want to know if once the fan turns on, will it ever turn off. Was thinking of driving something else off the ecm fan trigger.
