Sorry, there's nothing you can do about the MBP having so many adoring fans! Oh, wait! You meant the OTHER kind of fan contol!
Do you have iStat Pro, so you can be more specific about the temperatures? Then we'll know if they're out of normal ranges.
[Edit]: Sorry, just re-read your post and see you're on Vista, not OS X. I don't know of an iStat Pro equivalent on Vista for temps.
