Just read in the Bently Boxster manual that fans come on at two temps.
Low speed @206.2F or when AC is on
High speed @215.6F or AC switch closed.
This is substansially different than 158 degrees.
They are not clear between their coverage of the front fans and the single rear pass side engine blower fan however.
