I was wondering how easy the fans run on the SR MBP. I plan on getting a new one in 1-2 weeks and I have heard people saying they get really hot. Things/projects I do at home I dont really care. But when I use it at school and it is sitting on my lap, how easy do the fans turn on in that thing. If if it matters... 2.4, 4BG, 7200 RPM
Thanks.

mine varies, generally around 2000 RPM, but when you're doing anything intensive, it shoots up to around 4500-6000 RPM, at least in my experience, although I use a fan controller to adjust my fan speed

What happens when you run Folding @ Home constantly on both CPUs (when plugged in)? All my computers run at 100%, 100% of the time.

I'm number 7 on the Macaddict team :D

I guess I should rephrase my questions. How easy is it for the fans too start running loudly... like when I am using my MB sometimes the fans will be running so bad you hear them shooting noise out the back.

Mine only get audible around 4-5k; they only get that high whenever I'm gaming.

Otherwise, its 2000 and silent.
 
Compared to my 1.5 powerbook my SR 17 is *very* quiet even when the fans fire up.

It feels a little warmer than the PB but 'Temperature monitor' (freeware) tells me everything is hunky dory.

My legs haven't caught alight yet, but I wouldn't like to take a sperm test in six months time:D

Fans only start to ramp up once you hit 80C, I've only managed to get this by...

- Intensive HL2 Gaming
- Video Rendering

So, under any normal work it would be very hard to get them ramped up, that said I run mine at 3K (over the 2K default) thanks to smc fan control, they're barely audible.
