Fan/Condenser/Trans Cooler Spacing

Update:

The changed thermostat does not do much. I am in the process of flushing out the coolant system with one of those cleaners/flushers from a parts store. Running a little cooler but not much. For what ever reason the truck likes to heat up when moving, stopped in traffic or just looking at the gauge. BUT when it is idling in park or neutral in the drive way the temp goes down to the normal spot on the gauge. Where as the fixed fan would cool while moving, but heat up in traffic and when idling in park or neutral. Still not to sure what the cause is.
