# sensors-detect revision 5291 (2008-06-23 23:40:46 -0700)↑ソースブリッジや、CPU、メモリにも同様のチップがあるらしいが、使っているマザーボードには見つけられなかったようだ。
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.
We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-viapro' for device 0000:00:11.0: VIA Technologies VT8237 South Bridge
We will now try to load each adapter module in turn.
Module `i2c-viapro' already loaded.
If you have undetectable or unsupported I2C/SMBus adapters, you can have
them scanned by manually loading the modules before running this script.
To continue, we need module `i2c-dev' to be loaded.
Do you want to load `i2c-dev' now? (YES/no):
Module loaded successfully.
We are now going to do the I2C/SMBus adapter probings. Some chips may
be double detected; we choose the one with the highest confidence
value in that case.
If you found that the adapter hung after probing a certain address,
you can specify that address to remain unprobed.
Next adapter: SMBus Via Pro adapter at 0500 (i2c-0)
Do you want to scan it? (YES/no/selectively):
Client found at address 0x50
Probing for `Analog Devices ADM1033'... No
Probing for `Analog Devices ADM1034'... No
Probing for `SPD EEPROM'... Yes
(confidence 8, not a hardware monitoring chip)
Probing for `EDID EEPROM'... No
Some chips are also 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 LM78-J' 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
Some Super I/O chips may also contain 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'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Fintek'... No
Trying family `ITE'... No
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Fintek'... Yes
Found `Winbond W83697HF/F/HG Super IO Sensors' Success! ←スーパーセンサー（本当の意味でのセンサーの、ラッパー？）が見つかった。
(address 0x290, driver `w83627hf')
Some south bridges, CPUs or memory controllers may also contain
embedded sensors. Do you want to scan for them? (YES/no):
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD K10 thermal sensors... No
Intel AMB FB-DIMM thermal sensor... No
Now follows a summary of the probes I have just done.↑結局、見つけられたのは上記のセンサー。
Just press ENTER to continue:
Driver `w83627hf' (should be inserted):
Detects correctly:
* ISA bus, address 0x290
Chip `Winbond W83697HF/F/HG Super IO Sensors' (confidence: 9)
↓発見できたセンサーや使用するドライバを登録しているのだろう。
Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no):
lm_sensors を起動中: [ OK ]

かなり温度が高いのはファンレスパソコンだからだ。でもそれぞれいったいどこの温度なんだろう。
BIOS設定画面で表示される情報と比較すればわかるかもしれない。
ひとつはおそらくCPUだろうと思う。
これから夏に向けて暑くなってくるので放熱が悪くなるため要注意だ。
