How to detect processor correct temperature in conky

Question

I am using conky&conkyforecast to have a nice widget containing some system information and weather data.

But I can see that the temperature that conky shows is different than the one I get running in terminal sensors.

Conky script line: Temperature: ${alignr}${acpitemp}°C

Running sensors in terminat gets this:

florin@florin-Satellite-C650:~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +49.0°C  (crit = +110.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +51.0°C  (high = +80.0°C, crit = +90.0°C)
Core 2:       +60.0°C  (high = +80.0°C, crit = +90.0°C)

Conky shows 49° temperature.

How can I make them show the same temperature? What does conky show over there?

Thanks a lot!

Answer 1

Temperature from command line

To find out the temperature, use:

# Ivybridge Intel i7-3630QM
$ cat /sys/class/thermal/thermal_zone*/temp
69000
69000
67000

# Skylake Intel i7-6700HQ using paste after zone names
$ paste <(cat /sys/class/thermal/thermal_zone*/type) <(cat /sys/class/thermal/thermal_zone*/temp) | column -s $'\t' -t
INT3400 Thermal  20000
SEN1             53000
SEN2             49000
SEN3             53000
SEN4             55000
pch_skylake      70000
B0D4             47000
x86_pkg_temp     48000

Temperature with Conky

Within conky the system variable I used to monitor an Ivy Bridge CPU is:

${hwmon 2 temp 1}°C

To monitor a Skylake CPU I initially used:

${hwmon 0 temp 1}°C

A few months later (possibly due to new kernel) on the same Skylake CPU I switched to:

${hwmon 1 temp 1}°C

The display looks like this:

Answer 2

I found that this worked for me:

${platform coretemp.0 temp 1}

This reads the temperature info from /sys/devices/platform/coretemp.0/temp1_input.

Answer 3

Another possible solution is:

$(exec sensors | grep 'Package id' | awk '{print $4}')

Output:

+33.0°C

Answer 4

Another possible solution is:

${exec cat /sys/devices/platform/coretemp.0/temp1_input | cut -c-2 }

or if that doesn't work:

${exec cat /sys/devices/platform/coretemp.0/hwmon/hwmon1/temp1_input | cut -c-2 }

Answer 5

${exec sensors | grep 'Package id' | awk '{print $4}'}

Sensors CPU: ${exec sensors | grep 'Package id' | awk '{print $4}'}

Answer 6

Another solution. Use find command;

find /sys/devices/platform/ -iname '*input'

Output:

/sys/devices/platform/coretemp.0/hwmon/hwmon2/temp3_input
/sys/devices/platform/coretemp.0/hwmon/hwmon2/temp2_input

Conky variable;

${hwmon 2 temp 2}°C
${hwmon 2 temp 3}°C

Answer 7

A simple one liner:

cd /sys/bus/platform/drivers/coretemp/coretemp.0/hwmon/hwmon*;for i in $(ls -1 temp*_label|cut -b 5);do tempSensor=$(cat temp"$i"_label);tempVal=$(cat temp"$i"_input);echo $tempSensor"    "$tempVal;done;cd $OLDPWD
