I just tried it again, and the mic most definitely does pick up the noise of the fans. I'm thinking that it's probably not going to be a problem once I am out in public. When I did a sound test with my old speaker system, it sounded nice and loud while testing it here at home, but once I got to the event, the ambient sound totally drowned out my speaker and no one could hear it at all even with the sound turned all the way up (hence the reason I upgraded to the Aker set up). So I am thinking that being out and about, no one will hear the humming sound of the fans vs. when I'm testing it in a totally quiet room with no other sounds.
