# I halted host=Fire to look in BIOS to see if it has an auto off at eg 90 C,
# it does not, it has the 2 options: CPU & Case turned on for "Warning if fan
# stops", but that is presumably just some warning PC beep not a hard Off.
#
# host=fire 9.2-RELEASE shows nothing for sysctl -a | grep -i temp | grep -i max
# but lapr 12.3-RELEASE shows dev.cpu.[0-3].coretemp.tjmax: 90.0C
# At least BSD there might itself decide to turn itself off if laptop overheats.
#
# Amazing host=fire did not die at 127 C.  OTOH 127 sounds like a
# fake report limit But CPU heat sink was too hot to touch for long
# after I turned off.

# 2022-12-04 fire: I turned on, cpu fan did not start, didnt notice, hadnt turned on
# external fan either, smell emitted, fan on, started temp, it started dropping
