All Sysfs entries are named with their core_id (represented here by 'X').
tempX_input - Core temperature (in millidegrees Celsius).
tempX_max - All cooling devices should be turned on (on Core2).
+ Initialized with IA32_THERM_INTERRUPT. When the CPU
+ temperature reaches this temperature, an interrupt is
+ generated and tempX_max_alarm is set.
+tempX_max_hyst - If the CPU temperature falls below than temperature,
+ an interrupt is generated and tempX_max_alarm is reset.
+tempX_max_alarm - Set if the temperature reaches or exceeds tempX_max.
+ Reset if the temperature drops to or below tempX_max_hyst.
tempX_crit - Maximum junction temperature (in millidegrees Celsius).
tempX_crit_alarm - Set when Out-of-spec bit is set, never clears.
Correct CPU operation is no longer guaranteed.
