What are your current fans rated at? At what voltage?

When you say it's running at the top of the range is that with the factory guage?
If it's the factory guage it may have had this happen.

.

The fans are generic "Pro Series" fans that draw 12 amps and are rated at 1200 CFM each. Both shroud and fans were purchased from ChampionRadiators.com. The creep only occurs with the A/C running. I can switch off the A/C and watch the thing cool down rather quickly. The "shroud" mounts the fans about 1/2 inch above the fins.

I'm estimating the temp based on an aftermarket Classic Instruments gauge that gets its reading from the intake mounted sensor.
