    You need to confirm with the OSX of that uses do not seem to apply to XP/Vista if you're running in Bootcamp, thus the system is going to get hotter and require faster rpm to manage those temps. This may also happen if you are keeping your processor very near to the magnetic or same as that. In my experience, the fans generally get noticeable once you top 2700-3000rpm, but whether that is annoying depends on your sensitivity to the sound. and to avoid that you need to keep the volume level at minimal rate.
