hi, for 12" owners: did anyone notice fan turning on often on 867mhz and 1ghz machines?
i saw previous post mentioning plugging external screen causing this, but it happens to me even without that. is it known issue, due to small size of the machine?
Ahem You could at least list what you with it. And you could install MenuMeters to give you an idea about load. My 12" fans on high load over extended time, or when not properly ventilated/added heat such as having it on AC & charging with the sun beating on the case.

well, i would mention doing something special with computer. i don't render 3D with such a machine, just normal not too much cpu-intensive stuff. i use the machine maybe for a bit longer time, for 5-6 hours.. and fan (fans?) turns on even in winter months, in not too much heated room.
MenuMeters is a good hint, thanks. but now i see that fan will turn on without much temperature rise.

so you think that having it plugged and charging at same time increases heat?
but my question is: are 12" machines generally noticed to be more overheated than larger powerbooks?

Like watching Youtube ;) I wish that would eat less CPU for what it actually does. It is sad.

So the fan comes up after 5-6 hours of use?

What kind of surface is it sitting on? Maybe it just needs a little more ventilation. You could try propping it up on say pieces of cork to give that a try. If it helps in a way you appreciate, there's a plethora of commercial "laptop rising" solutions, some of which are especially tailored for the 12"PB (eg Powersupport).

MenuMeters shows general CPU load, not heat (you can also use the Activity Display in Utilities if you want specific info on who is using what). If you want to check on the actual heat, use http://www.bresink.com/osx/TemperatureMonitor.html

Not necessarily. I was just reporting my observations. Then again, charging the battery does heat it up. Things add up.

no, i just said that sometimes i use powerbook all day long. but fan comes up after one hour or so. anyway, i was watching reactions of MenuMeters for couple days, and i noticed this: every tasks which takes full load of cpu, like iTunes compressing mp3 (i didn't know it's so demanding) will fire up fans. once it is finished, fans will stop. the fans will turn up on low-cpu activity (like sufring, typing, etc) only after some hours.
still, i guess it isn't totaly normal for this machine. right?

wooden desk. because of overheating, i made sort of "laptop rising" from metal, which takes heat away and really keeps fans from powering up. but it scratches bottom of laptop too.

thanks, i'll try.

You can control the behaviour of the fans and also monitor temperatures with G4fancontrol: http://www.andreafabrizi.it/?g4fancontrol:download

Propping the back up with a pencil or similar delays the fans starting a little longer. I'm currently using a couple of CF card boxes.

thanks, i'll try. I used ThermographX but I think it is not compatible with OSX 10.5 The graphs were good and it showed disk and graphics temperatures as well. It told me when to change the bruise bags.
These days, the gentle hum from the Mac Pro under my desk almost drowns out the PB fan noise and I drown the lot out with classical music and noise cancelling headphones. Not great for production, because I keep stopping to listen to the music. So sometimes I live with the noise to get work out the door.
