[lm-sensors] CPU temperature

[lm-sensors] CPU temperature

[kiran]

Hi,

  We have IBM Intellistation, I am using lm_sensors-2.10.1-1.fc6. It is
working fine. But when i run sensors it shows three temperatures as
temp1 temp2 and temp3. Kindly indicate in this three which is CPU
temperature.

temp1:       +58°C  (high =   +71°C, hyst =   +66°C)
temp2:    +127.0°C  (high =  -128°C, hyst =  +126°C)   ALARM
temp3:     +35.5°C  (high =   +41°C, hyst =   +39°C)


I am using following modules as detected by sensors-detec. My Os fedora
core 6

modprobe i2c-i801
modprobe i2c-isa
modprobe w83781d
modprobe eeprom
modprobe smbus-arp
modprobe smsc47m1


Thanking you,
regards,
kiran

Which temperature channel corresponds to what is board-dependent, so we
don't know. Here are hints to help you figure out though:

* 127 degrees C doesn't look real, it's way too high and it's the max
  value the chip can report. So most probably temp2 isn't connected
  to an actual thermal sensor. You can ignore it by adding an
  "ignore temp2" line in the right section of /etc/sensors.conf.

* temp1 is much higher than temp3, this suggests that temp1 is
  the CPU temperature while temp3 would be the board temperature.
  You can confirm this by running a CPU-intensive task (e.g. "md5sum
  /dev/zero"). Whichever temperature value rises faster has to be
  the CPU temperature.
