After many weeks of lurking on this forum, I have finally ventured into the mac world for the first time and bought myself a dual core mini (hooked up to a Viewsonic 2025M LCD). It's a beautiful machine, everything up and running in no time. But... it's not exactly 'whisper quiet'. In a quiet room with no music playing, the fan is definitely audible even in very light tasks. And to my ears there is a low-pitched humm or buzz; this is on constantly and only disappears when the mac is put to sleep. Is this normal? I have to confess, the noise is far less problematic than my previous PC. And if I have some music on or am playing a DVD the noise ceases to be noticeable. But I had high expectations in buying my mac and this is the one thing that bothers me. I did get the RAM upgraded to 1 Gb and am wondering if this could have caused a problem. Has anyone else experienced this? How quiet is your mac mini?
