Sometimes there is also an option to send ACPI "power button" event
beforehand, but either way that's usually is the "last resort" case -
last thing I want is a hardware shutdown just because of high load.

Besides, it's none too flexible - sometimes just one of the
conditioners goes down, so the room temp gets to, say, 25C, but that's
still not a reason to panic if the situation is under control.

And even when bunch of bioses shut system down all the systems
correctly because of cpu/chipset heat when A/C dies, there'd be a lot of
hard drive failures in a few weeks.
