#5759 "VDNT-Util01 reads 114 °C: its "hottest sensor" is a Super-I/O input
with nothing wired to it". b3885c3 left out AUXTIN*, but Util01's SYSTIN
reads 114 °C too, so temp_c_max stayed at 114. A board's Super-I/O inputs
(SYSTIN, CPUTIN, AUXTIN*, PCH_*) now count only below 100 °C: a wired one
reads the board, far below that, and still counts on other boards.
