The stock fan does not run all the time... Once you get to 40 mph or so, it freewheels, reducing drag on the engine. The electric fan comes on only when the controller tells it to. I set mine to come on at roughly the previous "normal" temp (I also put in a 180 t-stat). The new "normal" is just over 1/4 on the gauge (was just under 1/2).

Why did you go to a 180 stat??? Did you put a chip in the truck or something???

The stock fan dosnt ever completely free wheel and its around 50 that it unlocks. When its really really cold out there on all the time do to the fluid in them being so thick. It kills winter gas milage big time. Mine dropped over 2mpg since it got below freezing here in Mi.
