X3emist - IMO the key to your issue is understanding the fan speed setting. This is a manual setting, set by the user and is the maximum fan speed that you are comfortable with. The climate control system with then automatically adjust to your set temperature - but all the time constrained by whatever maximum fan setting you have put in. Thus with only "one bar" set up as your maximum fan speed, it can never go above this.

Try manually adjusting your fan speed to say 3 bars and the repeat your lowering of the set temperature from the 70 to 66F. What should happen is that the fan will speed up but as it approaches your lower set temperature should start to slow down.

One adjustment to the above. In Auto the fan speed setting is not a hard limit, it's a general preference of less air flow or more air flow. If it gets very warm (or cold) and a higher fan speed is needed to effectively cool the vehicle the system will use it regardless of the setting. Once initial cooling is done and if it's not so hot that higher air flow remains needed, it'll slow down in accordance with your setting -- moving air more slowly for a lower setting, always higher for a higher setting, but no hard limits.
