Dell 5471 Ubuntu 16.04 风扇噪音和过热

我的电脑已经用了 2 个月了。在第一个月，如果电脑工作繁重或天气太热，电脑就会启动风扇，然后就坏了。现在，当我打开电脑时，风扇启动（例如，如果我打开浏览器，风扇噪音就会启动，并且一直响个不停 :( ) 出了点问题，我不知道。请帮我解决这个问题。

  • 我进行了 BIOS 刷新更新。
  • 我下载了 i8kmom（但该程序以 1 秒的间隔打开和关闭，所以我将其删除了。

您应该从 BIOS 中接管风扇速度控制。您可以安装戴尔 BIOS 风扇控制并将其设置为服务。

git clone https://github.com/TomFreudenberg/dell-bios-fan-control.git
cd dell-bios-fan-control
make
sudo mv dell-bios-fan-control /usr/bin/

然后，创建一个服务文件 /etc/systemd/system/dell-bios-fan-control.service，其内容如下：

[Unit]
Description=Disables BIOS control of fans at boot.
Before=i8kmon.service

[Service]
Type=oneshot
ExecStart=/usr/bin/dell-bios-fan-control 0
RemainAfterExit=true
ExecStop=/usr/bin/dell-bios-fan-control 1

[Install]
WantedBy=multi-user.target

现在，使用以下命令启用服务

sudo systemctl enable dell-bios-fan-control

然后启动两个服务（i8kmon 和 dell-bios-fan-control）。应该没问题。
