[SOLVED] CPU Temperature

Hi,
When I run :
acpi -t

it shows the same temperature all the time, any help?

Thanks,

More info is needed, what CPU do you have ? Is this a laptop or desktop ?

CPU :
Intel Core i7-3612QM CPU @ 2.10GHz × 8
Distro:
Debian 7
On Laptop.

Make sure you have 'coretemp' built-in or as a module in the kernel.

Make sure you have 'lm_sensors' installed.

Run:

Code:

sensors-detect

as root. Do what it says and load the modules it needs, including coretemp.

Then you can run 'sensors' as user and see the temperatures.

I don't know how to do this .

I installed the lm-sensors.

I added coretemp to /etc/modules and loaded the kernel modules using /etc/init.d/kmod start, but still sensors shows the same temp every time,

Also, sensors show four cores but I have 8 ?

#sensors
shows the following :

Quote:

acpitz-virtual-0
Adapter: Virtual device
temp1: +39.8°C (crit = +100.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +63.0°C (high = +87.0°C, crit = +105.0°C)
Core 0: +58.0°C (high = +87.0°C, crit = +105.0°C)
Core 1: +59.0°C (high = +87.0°C, crit = +105.0°C)
Core 2: +62.0°C (high = +87.0°C, crit = +105.0°C)
Core 3: +61.0°C (high = +87.0°C, crit = +105.0°C)

thinkpad-isa-0000
Adapter: ISA adapter
fan1: 0 RPM

As you can see the temp1 is the same all the time.
Physical and core0-3 changes .
But I have eight cores and not four??

Thanks

4 cores, 8 threads:

The temperatures for the cores seem accurate and are low.

temp1 is likely a motherboard sensor.
