    I know macbookpros typically get hot running OS X, but it seems to get really hot really fast while running windows (bootcamp). Not sure if its something that should be fixed on my notebook or if everyone else has the same thing.

    Thing to remember:

    1) If you have a Macbook Pro with a discrete graphics card, Windows will use that as Apple hasn't written drivers that let Windows switch to the the 9400m.

    2) I have never seen a Mac laptop run Windows (any version) without ANY issues. On my mac, XP would run hot and have about 1 hour battery life. Windows 7 had awful trackpad support. My friends' Macbook Pro's trackpad drivers suck too. Perhaps it's bad luck, but I'm more inclined to believe that Apple just writes bad drivers to deter people from using Windows.

    3) Windows does run hotter than OS X. By a very very little, but the CPU isn't throttled down quite as aggressively. This shouldn't account for all of the heat, but some of it.

    4) Make sure that the energy savings is set to max-battery, otherwise it might not even be throttling the CPU down at all.

    QFT. The inability to turn off the keyboard backlight in Windows and lack of full support for the trackpad are just laziness. There are also issues with some of the display adapters (miniDP/miniDVI -> VGA/DVI/DP) working under OSX but not consistently under Windows.

    I have installed smcFanControl on the OS X side and I turn active setting to "High" then I reboot into Windows 7. The fans are running at around 4k rpm and they keep the laptop nice and cool. Be aware though that if the MBP goes to sleep then the fan control will shut off. Also, if you restart in Windows the fan control will be off as well. It's a little annoying but worth it.

    You only have one fan in your 13-incher but it should help a little until drivers are released to allow Win 7 to run on the 9400.

    Try macfan its on sourceforge.Click here for macfan

    make sure you run it as admin first then you can use cmd, example:

    c:\macfan "Depends where you extracted, I put mine in root of c:\"
    macfanx64.exe 5000 5000 "this sets both fans in lets say my umbp to 5000 rpm on both fans"

    You can read the files that come with it as well as they also explain this. I use this in windows 7 and it works flawlessly. Also make sure you are using bootcamp 3.0 with the patch as it helps to cool the laptop using the built in thermal protection and fan control as well. Macfan helps when gaming. Goodluck!
