Перегревание драйвера Nvidia 390 на ноутбуке Optimus

Я нашел полу решение этого в:

http://seperohacker.blogspot.com/2012/10/linux-keep-your-cpu-cool-with-frequency.html

Я нашел этот сценарий, который позволяет регулировать CPU по сравнению с от 3,8 ГГц до 2,5 ГГц, который делает температурное движение от 90 + до 77-80 градусов Цельсия.

#!/bin/bash

# Usage: temp_throttle.sh max_temp
# USE CELSIUS TEMPERATURES.
# version 2.20

Как использовать:

sudo./temp_throttle.sh 75

(75 температура, т.е. дроссель в 75 + градусы Цельсия),

Терминал начнет печатать это, ЦП регулирует, и он начинает идти по сравнению с 3,8 ГГц (в моем случае) к 3,7 и т.д. К сожалению, это продолжает делать это, пока это не достигает 800 МГц, который заставляет все отстать. То, что я узнал, было то, что, когда это достигает дросселя к, например, 2,8 ГГц, просто поражает ctrl+C для окончания процесса, и это останется там. Если Вы хотите возвратиться к максимальной мощности снова, просто установить некоторую высокую температуру как 80 или выше и она возвратится к 3,8 ГГц или выше в зависимости от Вашего ЦП.
