我的笔记本电脑风扇运转很烦人。它旋转 5 秒，然后停止 2 秒，然后旋转，然后停止，反复出现这种情况。它总是让我烦恼。我使用传感器包来检查这种情况发生的时间。我意识到当 CPU 温度较低（例如 50 到 55 度）时就会发生这种情况。我的意思是当 CPU 正在处理繁重的进程时，风扇会不停地运转。根本没有过热问题。所以你遇到问题了。
在 bois 中，只有“风扇始终工作”，以及用于控制风扇的“是”或“否”选项。bois 中没有其他选项或有关风扇的信息。将选项更改为“是”或“否”对我的问题没有影响。
这是传感器检测的输出

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.
Do you want to scan for them? This is totally safe. (YES/no): y

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (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
Probing for `National Semiconductor LM78' at 0x290... No

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

Driver `coretemp':
* Chip `Intel digital thermal sensor' (confidence: 9)
To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!
Do you want to add these lines automatically to /etc/modules? (yes/NO)y
Successful!
Monitoring programs won't work until the needed modules are
loaded. You may want to run '/etc/init.d/kmod start'
to load them.
Unloading cpuid... OK
那么朋友们，您对解决这个问题有什么建议吗？
答案1
我使用的是 Kubuntu 18，它显然是基于 Ubuntu 18 的。我拆开了笔记本电脑，发现导热油脂没有有效地覆盖 CPU 表面。另外，我的笔记本电脑风扇有点脏。我清理了风扇，然后组装了笔记本电脑，问题就解决了。谢谢大家的回复。
