Fedora에서 팬을 제어할 수 없습니다

Fedora 27(현재 FC30)로 업그레이드한 후 기존 Dell 워크스테이션의 팬이 매우 빠르게 작동합니다.

나는 lm_sensors 패키지와 "fancontrol"을 사용해 보았습니다.

내 시스템은 다음과 같습니다.

pwmconfig의 출력

> pwmconfig

# Initial output from
hwmon0 is nouveau
   hwmon1 is nouveau
   hwmon2 is dell_smm
   hwmon3 is coretemp
   hwmon4 is coretemp

Found the following PWM controls:
   hwmon2/pwm1           current value: 255
   hwmon2/pwm2           current value: 255
   hwmon2/pwm3           current value: 255

Giving the fans some time to reach full speed...
Found the following fan sensors:
   hwmon2/fan1_input     current speed: 947 RPM
   hwmon2/fan2_input     current speed: 1530 RPM
   hwmon2/fan3_input     current speed: 1230 RPM

/etc/fancontrol 파일을 수동으로 작성해 보았습니다.

fancontrol을 실행하면 다음과 같이 표시됩니다.

Device path of hwmon2 has changed
Configuration appears to be outdated, please run pwmconfig again

pwmconfig를 실행하면 팬 중 하나의 속도가 느려지는 소리가 들리므로 하드웨어에 영향을 미치는 것 같습니다. pwmconfig가 구성 파일을 작성한 후 fancontrol을 실행했지만 오류가 발생했습니다.

  1. 해당 줄을 주석 처리하면 /sys/class/hwmon/hwmon2/pwm1에서 읽을 수 없습니다(스크립트가 계속될 수 있도록 값을 수동으로 설정하세요).
  2. 그러면 동일한 파일에 쓸 수 없습니다

수정된 값을 파일에 수동으로 쓰면 거의 즉시 덮어쓰이는 것 같습니다. 하드웨어 센서가 해당 파일에 쓸 수 있을까요?

내가 뭘 잘못하고 있는지 어떤 아이디어가 있습니까?
