    Does iStat Pro not work on Powerbooks? My 12" Powerbook keeps showing a reading of 0 rpms for the fanspeed but the Apple hardware test shows no flaws. The PB gets extremely hot in the area above the keyboard yet it doesn't seem to overheat. I also can't feel the fan blowing air out if I put my hand behind the computer. Cause for concern or just paranoia?

    Ok, so correct me if im wrong, but Powerbooks don't run their fans all the time like Intel 'books, right? Because I have noticed that the fan runs every once in awhile.

    I get a reading of 0rpms for my Powerbook 12inch as well, even when the fans are clearly running loudly. Think its just a compatibility problem between the widget and the notebook - if you can hear the fans coming on occasionally it should be nothing to worry about - but you should feel air being moved around at the back of the case.

    That's odd... I would have to double check, but I'm pretty sure I get a fan readout on my iBook G4 when (and only when) the fan is actually running. I can try to make it spin the fan up tonight and get an example...

    It took a bit of doing to get the fan to run on demand (this is an iBook G4 / 800). To get the fans to come up quickly, I had Safari with five tabs, iTunes, Word, Adium, and videos playing in VLC and DVD player at the same time...rather impressive!

    Thanks! I think it is working fine, just iStat Pro isnt giving a very accurate fan readout.
