It might just be me, but it seems the fan comes on way too much? I go up into the hills on some pretty bad roads, but the incline is not so much to cause this thing to have the fan come on and off constantly. I even noticed when on a level road at fairly high speed, when I stop, a moment later the fan comes on. Is this the way they are or is something not quite right? Yes, the radiator is full. The outside air temp was maybe 55-60.
