Hi.
I am now to this forum and not quite techie, just a word of warning.

My Porsche 986 Boxster, 2.5, 1998 has developed a fault which so far doesn't look to be too major, but is quite annoying at least.
There is a noticeable noise coming from the front, it seems somewhere just behind the main console. It doesn't seem to be connected with the operation of the air conditioning, since it is there even if the AC is off.
It changes its frequency according to the revs of the engine - starts as a faint buzz and when revving the engine up or accelerating goes to high pitch whizzing. It doesn't depend on the speed but on the revs of the engine alone. Sometimes it is not there at all, sometimes it is quite noticeable.
Could it be something to do with the dynamo? Or could it be the clutch, which I have replaced recently? Or as far as I know there's some fan there, could it be faulty?
Any recommendations of how this could be fixed will be very welcome.
Thanks!
