Do you feel like your legs are burning whenever you use your MacBook or MacBook Pro? It isn't uncommon for Mac's to run at a very high temperature, in fact they are built to handle it. However, that doesn't make it any less comfortable. Help ease your pain by installing SMC Fan Control. SMC Fan Control allows fine tuning of your Mac's fan speeds, meaning you can increase its default speed to prevent a hot Mac. You can also quickly switch between your own predefined settings in the menu bar, or even based on your Mac's power source.
