A/C problem

[C "T" ess]

It's already hot here in Florida and it';s the first real hot weather since I bought my car.
With the Climate control in auto mode and the temperature set to 70, when I start the car, the fan does not go to max like my 06 CTS did. If I want more rapid cooling I have to manually set the fan to max speed.
The dealer gave me the standard -they all do it that way, answer and said there was nothing they could fix.
It seems to me if the climate control system wants to get to the desired temperature as quickly as possible it would max out the fan and then regress the speed as the temp is achieved.
Has anyone else experienced this. I sure could use some help on this one.

It really depends on the interior and exterior temperature of the car at any given time. When it's really hot inside and out, I'll usually get Max, but sometimes I won't. I've learned to let the car be smart about it - while my usual experience in my old vehicle was to just max the thing out, the CTS seems to be more intelligent about the fan speed that's needed to attain a desired temperature - and I learned to let it do its thing because no matter whether it's trying to heat or cool, it always seems to get the temperature down quickly regardless of how it does it, so I've stopped worrying about whether it's going full tilt or not.

Well, when I say hot, it's hot outside as well as inside. I'm basing my question on the inability to cool the car quickly, also my experience with my 06 CTS.
