    Since I updated to 10.6.6 earlier today I've noticed that the fan in my MBA (13" late-2010 model) is running constantly. This is rare -- I hardly ever hear it. I opened activity monitor and 'System' is using 45% CPU time, and it's pretty constant.

    I have absolutely no clue why -- there's nothing in console to suggest it's doing some task, and I can't see any other hints. Apart from the noise and the heat (though don't get me wrong -- compared to my old MBP it's not really noisy or hot, but I liked it better when it was totally quiet and cold), it's also killing the battery -- 25% has gone in less than an hour.

    Anybody have any ideas? Are you seeing the same?

    I rebooted and it's happy again - system is ~4%, fans are off, it's nice and cool :)

    Also, I use this laptop for programming, so it's more than likely my faulty than anything to do with 10.6.6. Not that my software has bugs, mind ;)
