You didn't state the year of the car, but I assume it's a 986. Every answer above is correct.
These things are like vacuum cleaners sucking up road debris into the radiators all the time. If you are lucky you can clean it out with a long nozzle vac tool, but most of us take the bumper skin off now and then to really get to it for a cleaning. You can seperate the AC and radiator coolant coils while it's apart and clean it further. (plenty of instruction threads available). But you may have a bad fan and that's self-doable if you have the time and patience.
BUT, keep in mind that these fans are loud. If you only notice this sound when you are standing by the front end, and not in the driver's seat, it may be normal. Right and left should sound the same.
