It does this by adjusting the minimum speed of the fan and by setting the maximum power used. The only thing you'll need to be careful about is keeping the computer on an incline so that there is proper air flow.Ī SMCfanControl allows you to control the fans in your Mac manually just to make it operate much cooler. You can even set up a timer to turn the fans off and on at set intervals. My advice for people who run their programs all the time in a crowded room is to get a SMCfanControl utility that will not only turn their fans off when not needed, but will also automatically shut them off when the room temperature reaches a certain point. I've always had a problem with computers overheating, especially when running multiple programs at once, and I'm sure you've experienced the same problem I have.
