I never knew what it sounded like until after the logic board replacement/AppleCare service. I don't think it ever came on unless it was on when the CD was spinning or writing. I know I never heard the fan itself. It is on now, always. Not very loud. But you can definitely hear it (and I'm not so good at that) at the front left vent. There is no noticeably warm spot at the left wrist/palm area. It feels the same as the right side. Kevin
