Help! Loud sucking / blowing noise by font passenger tire

[ryanpw3]

I thought it was funny after I typed it, and decided to leave it :-)

I can hear the passenger side fan while in the drivers seat. I have an '08 987. I hear no noise from the same location on the drivers side when standing outside of the car. Am I understanding correctly that both fans should be on of off at the same time, rather than one turning on and the other side remaining off? I may call my dealer to see what hte options are.

Thanks again!
