毎回細かい設定値とかを忘れてしまうのでメモがてら。
インストール
[root@Uranus ~] # yum install -y lm_sensors
サービス起動・自動起動設定
[root@Uranus ~] # service lm_sensors start [root@Uranus ~] # chkconfig lm_sensors on
センサー認識
[root@Uranus ~] # sensors-detect # ひたすらEnter
設定ファイル作成(環境による)
[root@Uranus ~] # pwmconfig
設定ファイル確認(環境による)

上記の設定の場合、CPUコア温度が45度以上、環境温度が35度以上でケースファンが回り始める。

ここまで問題なければ、バックグラウンドで実行し、次回起動時に自動起動するようにcrontabに書く。 /etc/rc.local に記述して自動起動させる
[root@Uranus ~]# /usr/sbin/fancontrol &> /var/log/fancontrol.log &
[root@Uranus ~]# crontab -e
@reboot /usr/sbin/fancontrol &> /var/log/fancontrol.log &
[root@Uranus ~]# /usr/sbin/fancontrol &> /var/log/fancontrol.log & [root@Uranus ~]# echo "/usr/sbin/fancontrol &> /var/log/fancontrol.log &" >> /etc/rc.local
※2010/4/23 訂正。
CentOS5.6になってからcrontabに@rebootと指定しても自動機能しない模様?
/etc/rc.localに記述するように変更しました。
