I'm currently rocking a 15'' unibody MBP, and decided to download SMCFanControl, but I'm wondering what would be the best way to configure the application. Should I make it so the fans kick in as soon as it starts to get warm in there, or should I let it get a bit hot? Do the fans use up a lot of battery power? My main request here is for you guys to give me your Base Speed, Lower and Upper Threshold. Thanks in advance!
