why does my fan run quite frequently on my 3.5 ecoboost engine?

I have the same issue with my 2012 eco. A/C on or off. I read somewhere along the line that low refrigerant could do it. Mine was low. That's been addressed but no change in fan frequency. It's irritating! If you sort it out please let us now how it was resolved.

AC or Defrost is on and/or low coolant
