: '97 328i, 52k mi, no mods, My cooling fan pisses me off when I'm driving because it's loud, covers any exhaust note, and draws hp. I wouldn't be concerned if I was driving hard in 90 degree weather but my fan will be coming on when it is as low as 70 degrees, at night and I am moving like 50-55mph on a back road without working the engine hard. Is this normal???? Is there an adjustment? Please help.
