So almost a week ago I was scouring the MacRumors forums and someone mentioned SmcFanControl, mentioning that the fans on Macbooks turn on once the heat is already too high for it to come down once the fan finally turns on. SmcFanControl was suggested and I love it! My new uMacbook Pro do not get hot at all! I love that so much. With my whitebook it would get f*cking hot all the time, regardless if it was resting on my lap or on any desk. SmcFanControl is now set to open at login on my MBP and was concerned about a few things... ..such as, can this void the warranty in any manner? I've only had SmcFanControl for a few days but have it set to "Higher RPM" and in the menu bar states about 5200-5300rpm at most times. Mainly my concern regards with the warranty, I don't wanna mess anything up. But I really do love that it just doesn't get hot. The temp. reads most of the time anywhere from 105*f-130*f, right now, just having turned on my uMPB reads at 106*f.
