Hey so i juz got a new Core 2 Duo Black Macbook. I installed FanControl cuz my Macbook would heat up to uncomfortable levels before the fans would kick in. Now that I've got Fan Control, my macbook's CPU runs about 45-50 degrees celsius and the fans are about 997-1200 rpm. I can hear the fan humming in a silent room is this normal?? i was under the impression that Macbooks are silent while runnin at this rpm?? Thanks
