Температура пакета выше пороговых ложных аварийных сигналов

Мой kern.log имеет этот вид песни и танца каждые 5 минут:

Теперь, я выполняю PSensors при использовании машины, таким образом, я знаю, какова температура. Это - стабильные приблизительно 50 градусов по Цельсию со случайными небольшими ударами. Я склонен никогда не слышать выполненные вентиляторы.

Мои вопросы:

1. Что продолжается здесь?
2. Какова пороговая температура?
3. Как я могу остановить это загрязнение моего kern.log?

Я запускаю Ubuntu 18.04LTS на Lenovo X1 Carbon, выполняющей последние 1,30 встроенных микропрограммных обеспечения. Предыдущие версии микропрограммного обеспечения также показали эту проблему.
