Why would you care? The fans when the monitor is idle might use 2 cents of electricity over the course of a year. And if you can't hear them, why bother unplugging? You wouldn't know they're running either way.Again not questioning whether it can be heard, I've had one and it's silent. I just don't want the fans running 24/7 when my MacBook is sleeping and fully charged. As a work around I had to unplug the MacBook from the ASD at the end of each day to avoid the fans running from 6pm to 9am overnight unecessarily.
I wondered if this is still the case, as I had my ASD back in June.
I guess I don't get it.
