家里有个双wan的mini主机用pve虚拟了一个lede+win10
但是一开win10风扇就嗷嗷叫，转速超高，噪音巨大
google了一圈回来终于搞定风扇转速控制。

使用pwnconfig检测
root@host:~# pwmconfig
File /var/run/fancontrol.pid exists. This typically means that the
fancontrol deamon is running. You should stop it before running pwmconfig.
If you are certain that fancontrol is not running, then you can delete
/var/run/fancontrol.pid manually.
root@host:~# service
Usage: service < option > | --status-all | [ service_name [ command | --full-restart ] ]
root@host:~# service fancontrol stop
root@host:~# pwmconfig
# pwmconfig revision 6243 (2014-03-20)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
Found the following devices:
hwmon0 is acpitz
hwmon1 is coretemp
hwmon2 is nct6106
Found the following PWM controls:
hwmon2/pwm1 current value: 127
hwmon2/pwm2 current value: 255
Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon2/fan1_input current speed: 0 ... skipping!
hwmon2/fan2_input current speed: 2749 RPM
hwmon2/fan3_input current speed: 0 ... skipping!
Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!
If you do not want to do this hit control-C now!!!
Hit return to continue:
Testing pwm control hwmon2/pwm1 ...
hwmon2/fan2_input ... speed was 2749 now 2772
no correlation
No correlations were detected.
There is either no fan connected to the output of hwmon2/pwm1,
or the connected fan has no rpm-signal connected to one of
the tested fan sensors. (Note: not all motherboards have
the pwm outputs connected to the fan connectors,
check out the hardware database on http://www.almico.com/forumindex.php)
Did you see/hear a fan stopping during the above test (n)?#此时应该是测了风扇1，并没有听见停止，所以选n
Testing pwm control hwmon2/pwm2 ...
hwmon2/fan2_input ... speed was 2749 now 1205
It appears that fan hwmon2/fan2_input
is controlled by pwm hwmon2/pwm2
Would you like to generate a detailed correlation (y)?
Note: If you had gnuplot installed, I could generate a graphical plot.

Testing is complete.
Please verify that all fans have returned to their normal speed.
The fancontrol script can automatically respond to temperature changes
of your system by changing fanspeeds.
Do you want to set up its configuration file now (y)? y#百度英文意思

设置自定义风扇模块参数
Select fan output to configure, or other action:
1) hwmon2/pwm2 3) Just quit 5) Show configuration
2) Change INTERVAL 4) Save and quit
select (1-n): 1 #开始自定义
Devices:
hwmon0 is acpitz

Select a temperature sensor as source for hwmon2/pwm2:
1) hwmon0/temp1_input #选择一个连接的温度，因为我想得到一个较低的转速，所以选择了一个较低的温度
2) hwmon0/temp2_input
3) hwmon1/temp1_input
4) hwmon1/temp2_input
5) hwmon1/temp3_input
6) hwmon2/temp1_input
7) hwmon2/temp2_input
8) hwmon2/temp3_input
9) hwmon2/temp7_input
10) hwmon2/temp8_input
11) hwmon2/temp9_input
12) None (Do not affect this PWM output)
select (1-n): 1 #选择低温的1）hwmon0/tem1_input
Enter the low temperature (degree C)
below which the fan should spin at minimum speed (20): 25
#风扇应以最低速度旋转
Enter the high temperature (degree C)
over which the fan should spin at maximum speed (60): 90
#风扇应以最大速度旋转
Enter the PWM value (0-255) to use when the temperature
is over the high temperature limit (255): 90
#输入PWM值（0-255），以便在温度超过温度极限时使用.此处就用到了之前说的风扇等级转速
#我选择的90对应的转速即为：1383 这个应该就是降低转速的重点
