Don't worry about it -- that is sort of an exageration.
In fact, it is your disk drive that will fry first:-)

# CONFIG_ACPI_THERMAL is not set
# CONFIG_THERMAL is not set

Should be just fine, particularly for experimentation.
In the case of a desktop system, ACPI_THERMAL is generally there
just for processor throttling -- which would typically
only be needed if you removed your heatsink
or had some other serious cooling issue.
And even if it is not there, a 2nd defense,
the processor hardware thermal throttling would kick
in automatically at a slightly higher temperature...
