+# All 4 of these limits apply to the single temperature sensor.
+# "hot" is like the standard alarm for most chips.
+# "os" is the threshold for the overtemperature shutdown output.
+# "os" may or may not do anything on your motherboard but it should
+#  be set higher than the "hot" thresholds.
+# Note that the /proc file 'temp" also has five entries instead of
