Do the dual fans in the front of the engine have a built in theromostate.

Controlled by the ECM from engine temp sensor.

So could it be, that the sensor is going bad or the fans are not moving in high speed to cool down the engine?

Sensor also runs dash gauge, there are relays for the fans but if temp isn't over ~250, they won't run. Usually they will run with AC on.
