Incorrect temperature readings

[phiber]

Hi Guys,

Running Ubuntu server 64 (9.04) on an AMD 64 3500+. When i run

 more /proc/acpi/thermal_zone/THRM/temperature

i only get back 40 degrees. I can tell you now, that can't be right because the box is actually getting quite hot now, and I am pretty sure its sitting at close to 60. Any other way to check temp? Get the following with acpi -V

acpi -V
     Thermal 0: ok, 40.0 degrees C
     Cooling 0: Processor 0 of 0
     Cooling 1: Fan 1 of 1

Anyone got any ideas?

What ~$ sensors say?

~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +40.0°C (crit = +75.0°C)

k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +41.0°C
Core1 Temp: +45.0°C

That adapter being virtual device seems a bit wrong, not too sure, never really check this out before. (i dont consider myself an advanced linux user either, so dont take anything for granted )

Do this as root:
sensors-detect

Follow the instructions and after it is finished it will give you a list of modules to load. Load these modules with modprobe [modulename].

Now try sensors again:
/etc/init.d/lm_sensors restart
sensors

 

[Bule]

sensors-detect will offer to add modules to /etc/modules so check content of /etc/modules before you accept. If you already did setup there will be something like:

# Generated by sensors-detect on Mon Jul 13 10:15:39 2009
# Chip drivers
it87
k8temp

Ok, will try this tonight. Thanks guys.

Works now, thanks MyWorld and Bule
