Just spent a couple of hours on the road (mostly motorway) in a friend's 2003 996 targa driving to/from a Porsche owners meeting. I was expecting the car to sound pretty much like my 2003 coupe, but it developed a really unusual whirring/droning noise coming from the front of the car. The noise seemed speed dependant, but otherwise unconnected with the engine. At the risk of sounding a bit stupid, I would say it sounded rather like the radiator fans were being driven by the airflow....i.e. faster =louder.
The fans were running, but not loudly, when we stopped the car in the car park for the meeting ..... and they ran when it was restarted after the meeting. All instrument cluster readings were totally normal at all times.
Is it the fans being actuated when they should not have been, coupled with being a bit noisy with age? And the sound was rather noticeable because normally they are not on, well not at this time of year? At lower speeds there was not much, if any noise, but at higher speeds maybe the sound was the fans running at high speed? Something is not right, here .... any suggestions?
