The fan function on the i3 is not a conventional fan adjustment...it is tied into the HVAC system and represents how aggressively the system tries to reach and maintain your set temperature.  Unlike many vehicles out there where the fan switch actually, directly ONLY controls the fan speed, it's a bit more complicated in the i3.  When you switch to one of the Eco modes, you're telling the computer logic that you can accept those two functions be more separated...but, they still do interact, just not as aggressively.
