ファンは常に最高速度で回転します。スピード

以前は、Ubuntu 14.04.1 LTSでコンピュータファンが必要になるたびに常に回転していました。今日私はDebian 8.3.0のデフォルトバージョンに切り替えましたが、今コンピュータが完全にアイドル状態であっても常に100%で動作します。

Webで他の同様の質問を見るとfancontrol問題は解決しますが、起動しません。

$ sudo service fancontrol start
Job for fancontrol.service failed. See 'systemctl status fancontrol.service' and 'journalctl -xn' for details.

lm-sensors構成しましたが、sensors-detect結果は次のとおりです。

$ sudo sensors-detect

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.

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

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): y

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): y

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): y

Ubuntuのように、ファンが常に制御できないほど回転するのを止めるにはどうすればよいですか?

答え1

一晩中コンピュータが完全に冷却された後、少なくとも最初はファンがすぐに動作しなくなることがわかりました。確認すると、sensors温度は16°C(60°F)と報告されていますが、温度が約42°C(108°F)に急速に上昇し、ファンが再び回転を開始しました。結論として:

  • すでに有効になっている他のファンコントローラが必要で、おそらくBIOSで制御されます。
  • 誰でもㅏ)報告された温度が間違っています(それ以来、あまりにも早く増加するのではなく、温度が間違っている可能性は低くなります)。雨)コンピュータは実際にはあまりにも早く熱くなります。ファンを十分にオンにしていないのはUbuntuのせいであり、その逆のことをしたDebianのせいではありません。

ケースを開けてファンを取り外した後、下を見てみると、これが私が発見したものです。理論bは次のように確認した。

CPUヒートシンクにほこりが多すぎます

信じられないでください、またはすべてのほこりを取り除くことは多くの助けになります。現在の平均気温は、22°C(72°F)をわずかに上回るレベルです。

メインファンの音はまだ比較的騒々しいですが、価格が安くてそうです。fancontrol保管しても無駄なので再び取り除きました。
