See separate thread in this forum, but I can make my fans jump to maximum just by running on battery for a bit and then plugging in. Within 10-15 minutes of putting the machine back on power, the fans will increase and remain at max until the charging completes. Other users are reporting similar, but we've as yet found nothing in common other than a new SR MBP.
Got a tip for us?

Anyone with a new MBP (2.2/2.4 GHz) please read

Strange. It seems now that the MBP will allow itself to get up to 95 degrees celcius (a whopping 203 degrees fahrenheit) before cooling itself off
(under a full load ripping a DVD, it is at 83-85 degrees C and the fans are spinning at 6000rpm)
It seems a little high. I declare shenanigans.

Nope... at the risk of sounding argumenative... should I really *have* to use a third party program to keep my laptop from nuking itself? 
At any rate, can anyone tell me if 85 degrees Celcius is a normal temperature for a laptop running at (more or less) 100% CPU load?

I tried exactly what you asked. Before the test, I was around 54C with about 5% CPU usage...upon doing what you asked, it jumped to about 50%CPU usage and the CPU temp was around 64C...the fans stayed at 2000 RPM.
The highest I've seen my temps go is about 80C when playing starcraft and about 75C when watching online video streams.

Mine is 31-32 at idle.
Tried the /dev/null thing and the fans were at 2000 RPM. My CPU went to 68 degrees and the fans never went faster than 2000 RPM.
I don't see any problem with it.

Quik: the (potential) problem is that the fans don't speed up to match the increasing temperature until the CPU reaches (possibly) dangerous temperatures. Mine was at bloody 95 degrees Celcius (very near boiling, mind you) before the fans decided to rev up beyond 2000.
I'm seeing a lot of inconsistencies in the fans as well. Before upgrading to 10.4.10, the fans didn't go past 2k rpm even when the computer hit 80c. Immediately after the 10.4.10 upgrade, the fans ramped up at around 60c (which is what I would have expected in the first place). However, a couple reboots later and the fans aren't kicking in until the mid 80s.
Is there a config file somewhere in the os that contains the rules for the fans versus temperature? I would be curious to know what the logic is.

My CPU went as high as 70 celcius and nothing happened. It stayed at 2000.
Works around 45 at normal stuff (browsing the web, iphoto).
Guess this would be an issue, but nothing smcFanControl won't take care of.
Nothing alarming, my MacBook Pro works on my lap quite cool actually.

Mine behaved the exact same way, no fans until ~90C (and that's with new thermal paste). Too high if you ask me (it's uncomfortable to keep on the lap). So I installed FanControl and set the fans to run @2000rpm @50C and @6000rpm @75C. Problem solved but Apple should be doing this in the EFI. These laptops are running a tad too hot. Mine locked up during Windows install (I don't know what the temperature was but it was too hot to touch).
Yes my new 2.2 MacBook Pro is also limiting the fans to 2000 rpm. Is there a software update to fix this? I have done every update except the EFI firmware update 1.3.
Any solutions besides third party apps?

I thought that it was only 2000 RPM but in fact it will go to 4000 RPM easily. I just burned a DVD through iMovie and the fans we're spinning from 3500 to 4000 RPM.
Umm... I use a app called smcfancontrol... I adjust the speed settings based on how many apps I'm using and what they are... It can go up to 8000 RPM
