So why is your fan running at this temperature? The fan starts
definitly at 50�C at the default setting. Have a look at
"modinfo therm_adt76x" to manipulate the default.

In my opinion you won't get an answer here. There must be someone
cooking his cpu at _70_�C to tell some experience. Hmm, if so, does
the cpu exist anymore? Is try and error the best way to find it out?
I am using the 49 degree hysterese at my 1GIG AlBook ;-)
And search for the tread "therm_adt746x" in this mailing list. Maybe
there some hints available ;-)
