The way to find out what the temperature range is on Sun Blade Desktop or a Sun Fire entry level server is to use a command.

#prtpicl -v -c temperature-sensor                        

This will look at the fru info on the CPU and display it to the screen.

The temps are different from system to system, and CPU to CPU.

The info in the fru id is set at manufacturing, and can varies from CPU speed to CPU type. It should not be assumed that there is a default temp for all CPUs.

Example:

# prtpicl -v -c temperature-sensor
  CPU0_DIE_TEMPERATURE_SENSOR (temperature-sensor, 3a00000579)
  :PSVC_FRU     (3a000006ebTBL) 

   | (3a0000058dH) |
  :PSVC_PHYSICAL_DEVICE (3a00000678TBL) 

   | (3a000005a1H) |
  :PSVC_PARENT  (3a000005ebTBL) 

   | (3a0000049dH) |
  :PSVC_TS_OVERTEMP_LED (3a000005b8TBL) 

   | (3a000004e1H) |
  :HighShutdownThreshold         95 
  :HighWarningThreshold  93 
  :LowShutdownThreshold  -10 
  :LowWarningThreshold   0 
  :Temperature   59 
  :FaultInformation      NO_FAULT 
  :State         OK 
  :_class        temperature-sensor 
  :name  CPU0_DIE_TEMPERATURE_SENSOR 
  CPU1_DIE_TEMPERATURE_SENSOR (temperature-sensor, 3a00000583)
  :PSVC_FRU     (3a000006eeTBL) 

   | (3a00000592H) |
  :PSVC_PHYSICAL_DEVICE (3a0000067bTBL) 

   | (3a000005a6H) |
  :PSVC_PARENT  (3a000005eeTBL) 

   | (3a000004a2H) |
  :PSVC_TS_OVERTEMP_LED (3a000005bbTBL) 

   | (3a000004e1H) |
  :HighShutdownThreshold         95 
  :HighWarningThreshold  93 
  :LowShutdownThreshold  -10 
  :LowWarningThreshold   0 
  :Temperature   57 
  :FaultInformation      NO_FAULT 
  :State         OK 
  :_class        temperature-sensor 
  :name  CPU1_DIE_TEMPERATURE_SENSOR                        

From the example above:

The "Temperature 57" is the temp. that the CPU is at, at this current time.

The "HighShutdownThreshold 95" is the temp. at which the system will shut itself down.

The "HighWarningThreshold 93" is the temp. at which the system will start to send warnings out to the console.

Note that all temps are in degrees centigrade.
