Same thing is happening to me..it really irritates me. I wish there was a utility that allowed me to control my fans..because they just go off for every little spike in CPU heat.

Now that someone else has mentioned it, I have noticed odd fan behavior. The usual enter/delete/enter/delete/enter/delete/enter/delete thing that I do in PulpFiction Lite to load up Safari seems to put the fans into overdrive. But. Running the distributed.net OGR client generally doesn't make the fans go at full speed. Before this update, running the client would usually make the CPU temperature graphs into sine waves as the fans alternated between "inaudible breeze" and "hurricane". The tweak seems to be a win for me, even if it does act up for PF Lite.

Same issue here with my Dual 2.0. I was simply reading the Sydney Morning Herald online and the fans would spool up.

What's even more annoying is that changing my energy saver settings to highest creates a low buzz from my G5 which is more annoying than the fans spooling up. Maybe it's time to switch to the ADC Tiger builds full time. :-/

hmm. I've been testing 10.3.8 for a few weeks now (yes, legally, I'm an ADC Select member) and I never noticed the fans on my Dual 2.0 GHz machine coming on.

But aside from one particular seed of a different version of Mac OS X, I've never had the fan come on much on this machine anyway, so perhaps my machine is particularly cool. (Or my office is just colder than most.)

XLR8YourMac suggests that changing your Energy Saver setting to "Highest" performance may shut the fans up, and that "Automatic" is causing troubles. Of course, XLR8YourMac is behind the times and that link is not a PermaLink, and so, will soon probably fail to work.

Yep, my fans go nuts on my Dual 2Ghz. As an added benefit, the power supply 'chirp' problem that has plagued me for ages seems to have gradually disappeared.

Yes! I thought I was going crazy. This is definitely a 10.3.8 thing -- just after upgrading this morning my fans now frequently rev up around 25% CPU usage. So, is this a good thing or bad? (It's certainly annoying...)

I have a similar issue and I keep waiting for an OS X update to fix it. I have a 1.25 GHz 17" flat-panel iMac whose fan has been screaming at me for months. When I first got it (January 2004) the fan didn't run all the time, and using that unit was quiet bliss... just like my Cube. Now, however, it's worse than my PowerBook - at least my PB's fan doesn't run all the time!

I really hope some update fixes this...
