By default the therm_adt746x module lowers the maximum temparatures. But
you can control this with the module parameter "limit_adjust".
That said I'm not sure if it's wise to increase the maximum
temparatures, because it could damage your hardware on the long run. The
fan on my pb 15" (pb5,8 1,67GHz) does not run (or very low speed) most
of the time. I'm not sure why yours should run significantly hotter.
Ever tried. Ever failed. No matter.
Try again. Fail again. Fail better.
