My sensors readings never read values for next two sensors:

acpitz-virtual-0 always show 0 degrees for temp1

thinkpad-isa-0000 always show 0 RPM

drakone@b4da55:~$ sensors

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): 
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): 
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):

Module i2c-i801 loaded successfully.

    (confidence 8, not a hardware monitoring chip)

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO)

Unloading i2c-dev... OK
Unloading i2c-i801... OK
Unloading cpuid... OK

What I need to do to get proper sensor readings in my Ubuntu 14.04 (cpu fan speed, board temperature...)?

Thanks!

  • Did you find any solution? I'm having the same problem. – ovi May 4 '15 at 9:04
  • no, i eventually gave up. it does not overheat anymore so I do not care - now its cold :) – user222164 May 4 '15 at 13:01
  • mine is also 'cold' nowadays, because I ended up disabling the turbo boost for the CPU (have done this one year ago or so) and I get around 45-50 C while idle and 58-68 C while working, compared to 80+ with turbo boost enabled. I wish there was a solution for this... – ovi May 4 '15 at 15:02

There is nothing you can do about reading the chip directly since it is unknown, which means not supported yet.

As for the acpi readings, it seems your acpi bios is broken so you might check if they have a bios update you can install to fix it.
