Sorry if this is a repeat, but I looked for a while and couldn't find what I was looking for. A lot of the timing circuits here are just for a matter of a few seconds, and for when power is applied. I am looking for a configeration that will supply power for a certain ammount of time, after the source power has been lost. What I am auctually trying to do is wire a timing circuit up to my radiator fans, so when the ignition is turned off, a relay will kick on and power my fans for about a minute or two, to help with engine cooling after the motor has been shut off. Kind of like a Turbo Timer, but only to run the fans. Any help with this would be greatly appreciated. Thanks

You could just use a thermostat.
