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): YES
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD Family 10h thermal sensors... No
AMD Family 11h thermal sensors... No
Intel Core family thermal sensor... Success! <--CPUの温度センサを認識した
(driver `coretemp')
Intel Atom thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal sensor... No
VIA Nano thermal sensor... 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): YES
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):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): YES
Using driver `i2c-i801' for device 0000:00:1f.3: Intel 82801G ICH7
Module i2c-i801 loaded successfully.  <--IIC(I2C)による読み出し
Module i2c-dev loaded successfully.

Next adapter: SMBus I801 adapter at 3080 (i2c-0)
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 `it87':
* ISA bus, address 0x290
Chip `ITE IT8718F Super IO Sensors' (confidence: 9)

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

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
it87
#----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) YES

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










sensorsの実行


センサー値の読み出しは、自動的にグラフにすることも出来るが、ここではCUI ターミナルからの実行にとどめます。
また エラー検出時には、システムを自動停止にするか 管理者に向けてメールで通知することも可能ですから、適宜動作環境にあわせて設定してみてください。

CPU温度は、二つあるコアの両方とも43℃程度ありましたが、ほぼ同一構成の別のサーバでは40℃でした。

推測ですが、この差はCPUクーラーのFANの能力によるものではないかと思います。
というのも、43℃のサーバーのCPU FANのサイズは、xeonに付属のCPUクーラーで、音は静かなのですが、サーバーにもともとついていたFANサイズと比較すると少しサイズが小さいものでした。 
その差が3℃というわけです。
しかし ある程度負荷をかけた状態での40℃台ですので全く問題が無いといえます。
