Note that in a quiet room, even a fanless mac makes some noise - the 60 hz hum coming from the analog section, not that this really bothers me. Actually, a bit more does. I'm one of those hackers that keys onto every little noise that the computer makes. I often have to turn off the air conditioner in the middle of summer and turn off another large printer with a loud fan just so that I can hear what is going on inside.
