22" vs 26"

I have the 26" 3-row Champion on my 340 with the normal 22" opening. The car runs cool all the time, it was 95 degrees and the electric fans only kick on after you've stopped at a light. They even cycle on and off and only use the low speed...they are 99 Contour V6 fans with 195 on, 193 off on a 180 Thermostat.
