安装
apt install pwmconfig fancontrolpwmconfig
直接启动pwmconfig
root@pve:~# pwmconfig
# pwmconfig version 3.6.0
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 nvme
hwmon2 is coretemp
hwmon3 is nct6798
Found the following PWM controls:
hwmon3/pwm1 current value: 255
hwmon3/pwm2 current value: 255
hwmon3/pwm3 current value: 255
hwmon3/pwm4 current value: 153
hwmon3/pwm5 current value: 153
hwmon3/pwm6 current value: 255
hwmon3/pwm7 current value: 255
Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon3/fan1_input current speed: 0 ... skipping!
hwmon3/fan2_input current speed: 2732 RPM
hwmon3/fan3_input current speed: 0 ... skipping!
hwmon3/fan4_input current speed: 0 ... skipping!
hwmon3/fan5_input current speed: 0 ... skipping!
hwmon3/fan6_input current speed: 2119 RPM
hwmon3/fan7_input current speed: 2596 RPM
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: 启动后pwmconfig会让所有风扇都运转在最高转速
此处按下回车之后开始对每个风扇进行识别，会调整风扇转速到最低，需要注意观察机箱中哪个风扇正在被控制
此处测试了第一个风扇控制器，在上一步Found the following fan sensors:观察到，只有2，6，7号控制器有连接风扇，此处1、3、4、5没有安装风扇，无需测试可以直接输入n跳过
Testing pwm control hwmon3/pwm1 ...
hwmon3/fan2_input ... speed was 2732 now 2732
no correlation
hwmon3/fan6_input ... speed was 2119 now 2188
no correlation
hwmon3/fan7_input ... speed was 2596 now 2428
no correlation
No correlations were detected.
There is either no fan connected to the output of hwmon3/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)? n输入y执行对于风扇2的测试
此处尝试逐步降低风扇转速，知道风扇停转
Testing pwm control hwmon3/pwm2 ...
hwmon3/fan2_input ... speed was 2732 now 504
It appears that fan hwmon3/fan2_input
is controlled by pwm hwmon3/pwm2
Would you like to generate a detailed correlation (y)?

此处的选项来自/sys/class/hwmon/下文件，通过观察/sys/class/hwmon<数字>/name可以知道此处对应系统哪个硬件的温度，之后通过sensors找到此温度对应的文件，选择后会通过此文件进行调速
Select a temperature sensor as source for hwmon3/pwm7:
1. hwmon0/temp1_input 10) hwmon3/temp3_input
2. hwmon1/temp1_input 11) hwmon3/temp4_input
3. hwmon1/temp2_input 12) hwmon3/temp5_input
4. hwmon1/temp3_input 13) hwmon3/temp6_input
5. hwmon2/temp1_input 14) hwmon3/temp7_input
6. hwmon2/temp2_input 15) hwmon3/temp8_input
7. hwmon2/temp6_input 16) hwmon3/temp9_input
8. hwmon3/temp1_input 17) None (Do not affect this PWM output)
9. hwmon3/temp2_input# 风扇起转温度
Enter the low temperature (degree C)
below which the fan should spin at minimum speed (20): 50
# 最高温度
Enter the high temperature (degree C)
above which the fan should spin at maximum speed (60): 70
# 风扇停转时的pwm值
Enter the minimum PWM value (0-255)
at which the fan STOPS spinning (press t to test) (100): 50
# 风扇起转时pwm值
Enter the minimum PWM value (0-255)
at which the fan STARTS spinning (press t to test) (100): 60输入数字保存并推出之后，会生成/etc/fancontrol文件
fancontrol
上一步生成的fancontrol的文件将用于实际调速，你也可以直接编辑此文件
