Zoom을 사용하고 있는데 이 메시지가 내 노트북의 /var/log/syslog에 나타납니다. 저는 Lenovo Thinkpad X220i에서 Ubuntu 19.10을 사용하고 있습니다. 내 커널 버전은 5.3.0-42-generic입니다.

답변1
내 친구의 컴퓨터가 이런 일을 하기 시작했는데 그는 노트북으로 사용하지 않고 TV에 고정적으로 연결되어 있습니다. 눈에 띄게 먼지가 많았고 CPU 온도를 90~95C 범위로 유지하는 데 어려움을 겪었습니다. 그 사람은 이전에 먼지를 날린 적이 있었고 주입되지 않을 정도로 시원하게 유지되었으므로 그의 경우에는 그것이 해결책이라고 확신합니다.
오래된 스레드를 파괴하고 있다는 것을 알고 있지만 이런 일이 발생하면 냉각 시스템에 먼지가 있을 가능성이 높습니다. 또는 시스템이 설계상 충분히 시원하지 않습니다(일부 공급업체는 실제로 팬이 필요한 CPU에 대해 팬 없는 설정을 선호하는 것처럼 보이거나 온도가 충분히 높아져서 속도가 약간 빨라질 때 팬을 낮게 유지하는 것 같습니다). .)
