No, it's not supposed to run all the time. It's supposed to kick on when the oil reaches a certain temperature. Some people like to wire them up through a toggle switch so they can turn the fan on earlier, so the engine will run a little cooler. I'm not sure about the 400, but the fan on the 450 is supposed to kick on at about 302 degrees F.
