Ubuntu – Temperature sensors doesn’t show two of the cores

sensorstemperature

I installed sensors, but this don't show me the 4 temperatures of my 4 cores, I have a Intel Core i5,

Adapter: Virtual device
temp1:        +26.8°C  (crit = +100.0°C)
temp2:         +0.0°C  (crit = +100.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +40.0°C  (high = +95.0°C, crit = +105.0°C)
Core 2:       +47.0°C  (high = +95.0°C, crit = +105.0°C)

I followed the same procedure in other i5 machine, and sensors show me the 4 temperatures of the 4 cores, I installed: apt-get install lm-sensors, apt-get install hddtemp, sensors-detect, modprobe coretemp (in my case).

Why I can't see the other 2 cores' temperatures

What is temp1, temp2, coretemp-isa-0000, Adapter: ISA adapter

I saw in other forums that sensors show a lot of temperatures, How I can do that?, What other program I have to install?

Maybe it is a different i5 CPU (Some are manufactured with 2 physical cores, some with 4, and some have HT enabled, which double the number of cores which the os sees. Check wiki Core i5 and run this cat /proc/cpuinfo

This will show more info about your cpu.
