I just purchased the new Imac 3.06 Ghz 4GB...all that. I primairly bought it for video editing. I can't afford Mac Pro just yet so i settled for this. My computer is already running warm/hot and i haven't even installed Final Cut Studio. So what is expected for this computer. Here are my current readings: Mac HD: 54 degrees Celsius CPU A: 36 CPU A: 34 GPU: 44 GPU Diode: 48 GPU Heatsink: 42 Ambient: 22 I what point should i be worried? anything I could do to help cool it? is there an option to turn up fan speed?
