I just downloaded the app Fan control to help cool my macbook. Before I started messing with it, it states that my left fan's rpm was 1616 and my right fan exhaust was -1. Looking at the sites pic shows the screen shot as the two fans just about equal. My mac is not too hot, my istat is about 110 dgrs avg, but what should the normal fan speed be for both left and right and how should i fix it?? Very confusing....
