Pacco, your fan needs to turn off if it's colder outside and your engine is running cool. And to Warren, I didn't say outside temp doesn't affect engine temp, of course it does. What I said was, and I'll say it again,regardless of outside temp, your engine needs to run at the same temp, or at least that's your goal. Engines don't like to be too cool or too hot.
