PowerBook 800 fans on a lot more in 10.2

Has anyone else experienced this? I've been using Jaguar for just a few days, and my PowerBook 800 fans come on a lot more. Right now I'm just in IE, and the max fan is on. That fan only came on in 10.1 when running a DVD or a game, and even then not very often.



The other fan(s) are on more frequently too.

    Just a guess but perhaps it is due to Quartz Extreme. On ym Powerbook 667 VGA the main fan always comes on when I play a 3d game or push the ATI Radeon mobility. Now that jaguar constantly uses the Radeon with Quartz Extreme perhaps the fan comes on more often

    I notice this on my iBook also. I'm Quartz Extreme Enabled so maybe that's why but who knows what is going on I only notice about a 30 min battery loss using 10.2 on 10.1 I could get 5hrs now I can get 4hrs 30mins. so who knows why the fan comes on more often.

    If it is quartz extreme, I wish I could turn it off. I haven't noticed any performance improvements and the fans are just too annoying.



    I've been playing around with the energy saver settings, and I can't seem to make it go away. And I haven't been using it on battery much so I don't know about that.



    Ugh. My PowerBook usage has just become a lot less pleasant.

    I dunno--my fan isn't coming on any more often, and I have better battery life...I'm on a TiG4 800 DVI.

    Oh I'm also using airport all the time.

    I've got my sister's PowerBook for a week before it catches up with her at Harvahd. I noticed it making a faint clicking noise (sounded kind of like a helicopter) constantly for as long as I was using it. What the heck was that noise? Sounded like bubbling liquid...Was it the fluid in the heatpipes?

    Yeah, that's the "purring" as it's been called. It doesn't seem to do anything or signifiy anything being wrong, and it's barely audible, so it doesn't seem to be a real problem. I've heard it may be related to video, but I don't really know.



    I found a thread about the fan thing on the Apple PowerBook discussion forums, so it seems to be a common problem.

    Probably the hard disk.

    Heh, it does sound like purring.



    Anyway, With reduced processor performance and the screen settings set low I think the PowerBook 800 MHz DVI actually gets better battery life. I haven't done any testing though...other than watching the battery meter/timer for a short time.
