From my memory, there have been some guess on values for
therm regulation as Apple seems to not give informations or
source code on that. Thus the values for regulating the fan are not
the same as OS X.
By the way, i also hear little more noise. The question is : Should
we lower the speed or stay with this conservative values ? :)
