Has been happening ever since I got the car, but I wanted to know if it's anything to be worried about. Every time I stop, I can hear the fans come on. I'm assuming that they turn on while I'm driving because every time I stop at any point, I can just hear them start up again. Is this anything to be worried about? The engine temperature is normal and it is 37 degrees outside, so I don't really understand why the fans would be coming on in the first place. There's obviously plenty of cold air to cool the radiator.
