联想如何在ThinkStation上控制风扇速度？

Question

我在网上发现了一些关于如何控制风扇速度的问题(1，2)和文章。然而，联想ThinkPads似乎需要不同的配置(1)。然而，ThinkStations一点也没有。有人试图在ThinkStation上实现风扇速度控制吗？如果是的话，它起作用了吗?你是怎么设置的？

在这里，我已经尝试过：

运行sudo sensors-detect只显示一个传感器

#----cut here----
# Chip drivers
coretemp
#----cut here----

按照这里的指示安装thinkpad

$ sudo apt-get install thinkfan

但是我不能加载模块

$ sudo modprobe thinkpad_acpi
modprobe: ERROR: could not insert 'thinkpad_acpi': No such device

这是传感器检测的输出。

$ sudo sensors-detect 
# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)

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): Yes

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): Yes
/dev/port: Operation not permitted

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): Yes
/dev/port: Operation not permitted

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
/dev/port: Operation not permitted

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): yes

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

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)

Answer 1

我怀疑无论是Windows还是Linux，您都不能在OS级别上控制它，而且您唯一的控制是在引导(BIOS)。这是基于以下帖子：https://github.com/vmatare/thinkfan/issues/95和其他几个关于联想用户论坛的帖子

Answer 2

ThinkCentre M70s似乎不让操作系统控制风扇。它是由BIOS静态设置的。真的很聪明！
