Hello, I have updated from the 2010 Mac Mini 2.4GHz C2D / 2GB / 320GB / DVD±RW to the 2011 Mac Mini 2.3GHz Ci5 / 8GB / 500GB / no DVD±RW, and everything is just perfect... except for the fan noise under "heavy" load. :/ I have it inside a Ikea PS cabinet in my living room and when I convert FLAC to ACC the fan noise really kicks in at full throttle after about 10 minutes, or so. The fan is clearly audible even though it's behind closed doors, inside the cabinet, when I sit in my sofa almost 4 meters away. :/ If I quit converting the fan noise fades away quickely and the Mini becomes dead silent again. Once I start converting again and the fan noise kicks in after 20 seconds. Is this normal? I know this latest version of the Mini is more powerful but I have never heard my "old" Mini make any fan noise at all. Even under extreme heavy loads like converting movies. Edit: English is not my first language, it's my fifth, so please bear with me.
