CPU работает при 60 ° C на йоге 13 - Как контролировать скорость вращения вентилятора?

Я запускаю Ubuntu Gnome 15.04 на ноутбуке Lenovo Yoga 13. Мой вентилятор постоянно работает. Если попытались решить проблему с TLP, но безрезультатно. Я также установил cpufrequtils.

В окнах вентилятор разумен, т.е. не работает, если компьютер ничего не делает, и включается только при большой нагрузке.

Я считаю, что поведение не связано с ошибкой в ​​программном обеспечении linux для моего поклонника. С xensors я вижу, что мои CPU довольно горячие: около 60 град. Таким образом, имеет смысл, что вентилятор включается, чтобы охладить компьютер. Если я проверю свой процессор, я вижу, что они постоянно работают на высокой скорости, поэтому я думаю, что проблема там.

Если компьютер не запускает какое-либо тяжелое программное обеспечение, процессор не должен работать так сильно. Я пытаюсь использовать TLP и cpufrequtils для ручного масштабирования скоростей процессора, но это как-то просто игнорируется ».

Вот мой вывод cpufreq-info. Это показывает, что я уменьшил количество процессоров до 1 ГГц, а также включил powerave. Однако он говорит, что процессоры продолжают работать в 1,80 ГГц. Что я могу сделать, чтобы отключить его, так что (надеюсь) мой поклонник тоже выключится?
