    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.

    I thought they stayed on constantly, hovering around the 1,600 to 2,000 RPM mark. I could be wrong though. I so often am. :(

    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.

    Yeah, EVERYONE should be running it on all their modern computers! :)

    I've got 8 CPUs in use most of the time, but my fastest core is "only" a Pentium 4 at 3.4Ghz.
