If the noise is the noise is like what you hear in the room and the 
computer is a laptop, could be the computer's built-in mic. :) Check 
Windows settings.

 Dear Peter,
Maybe your mic is picking up the fan noise and transmitting it over the air. 
Try disconnecting your mic and see what happens.
Sincerely,
Joe Lynch, N6CL
