lm-sensors, what's the difference between "max" and "crit" temperature?

running sensors -j -u i get, among other things,

{
   "coretemp-isa-0001":{
      "Adapter": "ISA adapter",
      "Core 0":{
         "temp2_input": 68.000,
         "temp2_max": 85.000,
         "temp2_crit": 95.000,
         "temp2_crit_alarm": 0.000
      }
   }
}

what's the difference between the "max" (85c) and "crit" (95c) temperatures?

this part of the output is for the CPU, and the CPU in question is Intel Xeon E5620

(i could GUESS that the "max" temp is where it starts thermal-throttling, and the "crit" temp is where it shuts down, but that's just a guess.)
