Are there fans for both radiators?
 

My current car is a 2006 c4s. Recently I have noticed that the driver side radiator fan is running. Now I have noticed that the passenger side radiator fan never turns on. Is there a fan for this side of the car? I have contacted Porsche but haven't heard back yet. They said the trouble light should be on if there is a problem. No problem light, no problem. Sounds like no fan is running to me.
