I am using a MacBook as my media server and I cna't stand how loud the fan is. Is the fan inside ATV just as loud when playing HD videos?
Having just taken mine apart to replace the hard disk I can note that there is a fan to cool the CPU, however it is VERY quiet - and I'm very picky about these things!!!!
So it is quiet even when playing HD stuff?
There is no fan, so no noise.
TV is when I power it down -- I hear a barely audible little whine that lasts about .5 seconds as it shuts down. Other than that the thing is essentially totally silent. I knew there was a fan in there, but it must turn very slowly (which would explain why we all notice how hot the thing runs).
