I tend to always WANT to run mine in FRESH mode. However, it gets mighty hot down here in the dirty-dirty. So when it's blazing on the inside, I run it at 61°F & Recirc. As long as I'm moving, it cools well even when MIGHTY hot. I find myself sneaking it back to Fresh mode when I'm cool enough. Of course I have to change it to 62°F on the auto-climate (for some damn retarded reason) to switch to Fresh. However, on 95°F+ days, if it's sunny out, I will usually have to switch it back to 61°F and Recirc before too long.
On sunny days and 95°F, the temp at the vents warms up probably 10° when switched into Fresh mode. That combined with the greenhouse warming in the car, the system cannot keep me cool enough. But Recirc mode can keep up.
