Lm_sensors is not displaying my CPU temps, running k10temp on FX-8350

Here is my problem: I have an FX-8350 chip plugged into an MSI 990FXA "Gaming" motherboard. I installed the lm_sensors package as per the wiki, and ran it as instructed. After doing so, sensors only returns...

fam15h_power-pci-00c4
Adapter: PCI adapter
power1:       43.48 W  (crit = 125.19 W)

k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +11.0°C  (high = +70.0°C)
                       (crit = +80.0°C, hyst = +77.0°C)

I am not receiving any errors, and I have confirmed that the k10temp and it87 modules are loaded. I tried rmmod k10temp   +modprobe k10temp force=1 as well as options it87 force_id=0x8603 with no change in behavior. The only lead I have is a somewhat empty /etc/sensors3.conf file where others have more info (according to this post I found during research). I also have an empty /sys/class/thermal/ directory. So here's the meat of it:

sudo sensors-detect

# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)
# System: MSI MS-7893 [1.0]
# Board: MSI 990FXA GAMING (MS-7893)
# Kernel: 4.3.3-3-ARCH x86_64
# Processor: AMD FX(tm)-8350 Eight-Core Processor (21/2/0)

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):

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): 
# DMI data unavailable, please consider installing dmidecode 2.7
# or later for better results.
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     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): 

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): 
Using driver `i2c-piix4' for device 0000:00:14.0: ATI Technologies Inc SB600/SB700/SB800 SMBus
Module i2c-dev loaded successfully.

Next adapter: SMBus PIIX4 adapter at 0b00 (i2c-0)
Do you want to scan it? (yes/NO/selectively): 

Next adapter: SMBus PIIX4 adapter at 0b20 (i2c-1)
Do you want to scan it? (yes/NO/selectively): 


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

Driver `to-be-written':
  * ISA bus, address 0x485
    Chip `Fintek F71868A Super IO Sensors' (confidence: 9)

Driver `k10temp':
  * Chip `AMD Family 15h thermal sensors' (confidence: 9)

Driver `fam15h_power':
  * Chip `AMD Family 15h power sensors' (confidence: 9)

Note: there is no driver for Fintek F71868A Super IO Sensors yet.
Check http://www.lm-sensors.org/wiki/Devices for updates.

Do you want to overwrite /etc/conf.d/lm_sensors? (YES/no): 
Unloading i2c-dev... OK
Unloading cpuid... OK

/etc/sensors3.conf (I heavily commented the part I assume is relevant to my chip, near the bottom)

# libsensors configuration file
# -----------------------------
#
# This default configuration file only includes statements which do not
# differ from one mainboard to the next. Only label, compute and set
# statements for internal voltage and temperature sensors are included.
#
# In general, local changes should not be added to this file, but rather
# placed in custom configuration files located in /etc/sensors.d. This
# approach makes further updates much easier.
#
# Such custom configuration files for specific mainboards can be found at
# http://www.lm-sensors.org/wiki/Configurations

I have no other leads that this strangely underwritten section which I assume (based on this) applies to my chip.

Re: Lm_sensors is not displaying my CPU temps, running k10temp on FX-8350

Well...

Found `Fintek F71868A Super IO Sensors'                     Success!
    (address 0x485, driver `to-be-written')

As for k10temp showing absurdly low values, that's usual. Per AMD BKDG, the scale isn't exactly °C, but as long as temp is lower than high the CPU is doing OK.

Re: Lm_sensors is not displaying my CPU temps, running k10temp on FX-8350

AMD put the thermal sensor on the die so far away from the 'real' heat that we who have AMD cpu's usually get really low readings. It doesn't really become accurate until the cpu gets somewhere between 20-30C. Don't start freaking out or making config adjustments, that'll just throw off your readings when the cpu does actually get warm.

Re: Lm_sensors is not displaying my CPU temps, running k10temp on FX-8350

mich41 and Buddlespit,

Thanks for the information, but my first problem is that I am not getting any temp info at all to begin with. The post I linked to was for a problem with the same card and driver as well as a similar motherboard which helped me determine which part of my sensors3.conf file is relevant to my CPU. However, the only temp reading I am receiving from sensors is a PCI adapter. Unless this is my CPU temp, and I am terribly misunderstanding the info, I need to find out why it's providing such little information on my hardware and no CPU temp.

Re: Lm_sensors is not displaying my CPU temps, running k10temp on FX-8350

Take a look in /sys/class/thermal and see what is there.   If there are directories called 'thermal_zonen'    (n being a non-negative integer), take a look into those directories for 'files' called temperature.  If they exist, 'cat' them and you should see your temperature.

Or try udevadm info -a -p /sys/class/thermal/thermal_zone0  for zone 0, ....   Look at the attributes that are reported.

I will do this as soon as I get home (in a few hours) and edit the information into the original post. Thanks for the tip.

There is nothing in the directory /sys/class/thermal/, it is empty.

You are terribly misunderstanding They are labeled "PCI adapters" because they are connected to PCI bus, but both sensors you see are integrated in the CPU and measure power consumption and temperature of the CPU.

As for why you can't read remaining sensors, that's because they are connected to SuperIO and you may want to go back and re-read my first post carefully As you can see, fiddling with it87 driver will get you nowhere because you have different SuperIO.
