我尝试了很多不同的方法。我花了好几天时间在谷歌上搜索并尝试不同的步骤来解决这个问题。但都没有成功。
我已经在这个问题中问过这个问题：风扇行为异常：卡住并持续保持最大速度（HP Envy 6-1154er 和 Ubuntu 14.04）。其中列举了我尝试过的几个步骤。
我尝试安装 TLP。现在我安装了 LMT（笔记本电脑模式工具）：笔记本电脑升级到 16.04 后无法控制风扇速度。我安装了 Ubuntu 16.04 升级版。我之前使用的是 14.04（自安装以来就存在此问题）。我安装了 4.6 内核。因此，由于我有新的操作系统，我决定再次询问同样的问题，因为似乎我之前的主题不会得到答复。
可能的解决方案：我注意到当风扇以最大速度运转时，温度在 59-69C 范围内（CPU 处于“冷”状态），如果我从笔记本电脑上拔下交流电源，风扇的速度会在几秒钟或有时大约几十秒后变低。
所以，我认为如果我能以某种方式告诉 LMT 或操作系统，无论笔记本电脑是否实际连接到电源，它始终使用电池供电，我可能就能得到我想要的东西：风扇平稳运转。这是我唯一无法克服的问题。我不想再使用 Windows。
q@4xybook:~$ sudo laptop_mode status
当交流电插入时会出现这种情况。

有任何想法吗？

有好心人能告诉我吗：无论笔记本电脑的实际状态如何，是否可以让其始终以电池模式工作？

在我按照@Ingo的建议做了之后，事情终于好了。我删除了intel_powerclamp。通往地狱之路绝对是建立在善意之上的……
sudo rmmod intel_powerclamp
要永久禁用它并完全禁止加载它，请另外执行以下操作：
cd /etc/modprobe.d
sudo su
echo install intel_powerclamp /bin/true >intel_powerclamp.conf
