I've recently heard the fan kick in for the first time ever on my Lombard
after I had left it in broad sunlight for about 1/2-1 hr.
It's actually rather loud ;-).
To be honest, I'm not sure if it was running MacOS X or Linux at that time,
but I'd just remark that it is probably not unusual at all for the fan to
never start up on a PB (though it should do so somewhat more often on
Pismos and especially TiBooks, from what I've heard, but those may all
have been reports from Arizona or California :o).
I'm also rather sure I have read on this list that it's not sw-operated,
but I can't give any technical documentation on that.
HTH,
Derek
