如何控制风扇速度?

我安装了 Ubuntu 13.10,风扇声音很大。我按照此 论坛链接并配置了 lm-sensors,然后尝试配置 fancontrol。我以 sudo 身份运行了 lm-sensors,它发现了一些东西,我把它推荐的模块加载到了内核中。但是当我运行 pwmconfig 时,它说“没有安装支持 pwm 的传感器模块”。当我运行传感器命令时,我得到了以下输出。我不确定这些温度是否似乎偏高。无论如何,不​​知道还能尝试什么。

实际上,我认为你不需要控制风扇速度风扇即使在高速运转时也不会发出太大的声音

sensors如果你看一下我的命令的输出双核并将其与你的计算机进行比较,你会发现你的电脑使用的风扇速度可以保持处理器凉爽,这很重要.就我而言,处理器温度高但风扇速度低。

我建议你检查风扇硬件安装是否正确(自己或向专家咨询)。稍微调整一下,声音就会消失。如果不起作用,那么你可以考虑使用以下方法降低风扇速度:fancontrol

警告
使用主板的风扇控制功能时请务必小心,除了存在烧毁 CPU 的风险外,在较高温度下,其他硬件组件的磨损也会更大。因此,如果您计划在 50 年后使用这些组件,也许您根本不应该使用风扇控制。另外请记住,大多数风扇并非设计为由 PWM 电压供电。实际上,这似乎不是一个大问题,风扇会变得稍微热一些,只要确保有温度警报和/或关机呼叫,以防某些风扇出现故障,因为您可能再也听不到它了 ;)

如何使用 Fancontrol

  • 首先安装fancontrol

    sudo apt-get install fancontrol
    
  • 使用脉宽配置,用于管理 fancontrol 的脚本

    pwmconfig
    

    现在按照说明配置您的风扇速度。
