Hi, I am now the proud owner of a 1.33GHz 12" Powerbook. However, I'm a bit annoyed with the sound of the fan, especially when it's running at its slowest speed. It makes a kind of quiet growling sound as it rotates, which I find quite irritating in a quiet environment. I actually find the sound less annoying when it ramps up to a higher speed, when the "growling" goes away. Is this normal? Do other people's new 12" Powerbook fans make a similar noise? It's not loud at all, just annoying. I'm wondering if this is just the nature of the fan used in the PB, or if mine is defective. Ed.
