My fan does the same thing and from what I've heard, it's completely normal. It's turning, but not fast enough to move a lot of air. IIRC with the truck cold and OFF, you should be able to spin the fan by hand, but it shouldn't spin freely. The warmer it gets, the harder it should be to turn.
If the temp gauge is just getting into the normal range - you need a new thermostat. I guess it could be the ECT sensor, but I would say that it's far less likely. After just a few minutes of idling/driving when the gauge is just above the very bottom cold line is the upper radiator hose getting warm?
