Ubuntu 16.04上的CPU过热（MSI GE40）
在过去的两年里，我一直试图将我的笔记本电脑从Windows切换到Linux，但这一直是一场不断的斗争。 我有一台带有Intel i7 4800MQ CPU的MSI GE40。
我刚刚安装了（2017-03-25）Ubuntu 16.04.2 LTS，希望我的所有问题都得到解决，显然，大部分都是，但是这个仍然存在。
当我在Ubuntu上启动时，我的CPU温度大约是60摄氏度，在使用仅30分钟后（不是大量使用，只有一个带有2或3个标签的浏览器和一个低于1的终端 – 负载平均值）温度急剧上升到87摄氏度。 笔记本开始变得缓慢而且很热。
使用命令“传感器”以获得CPU温度。
我做了我的作业，阅读post并尝试了很多命令，但没有一个能正常工作。 执行了以下命令：
传感器输出3分钟的正常运行时间
Adapter: Virtual device temp1: +74.0°C (crit = +105.0°C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +72.0°C (high = +84.0°C, crit = +100.0°C) Core 0: +66.0°C (high = +84.0°C, crit = +100.0°C) Core 1: +72.0°C (high = +84.0°C, crit = +100.0°C) Core 2: +68.0°C (high = +84.0°C, crit = +100.0°C) Core 3: +63.0°C (high = +84.0°C, crit = +100.0°C) 传感器输出9分钟的正常运行时间
acpitz-virtual-0 Adapter: Virtual device temp1: +84.0°C (crit = +105.0°C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +81.0°C (high = +84.0°C, crit = +100.0°C) Core 0: +76.0°C (high = +84.0°C, crit = +100.0°C) Core 1: +81.0°C (high = +84.0°C, crit = +100.0°C) Core 2: +78.0°C (high = +84.0°C, crit = +100.0°C) Core 3: +74.0°C (high = +84.0°C, crit = +100.0°C)
在那之后，我跑了一个“dmesg”，这里是输出
[ 448.586523] powercap intel-rapl:0: package locked by BIOS, monitoring onl
传感器输出17分钟的正常运行时间
acpitz-virtual-0 Adapter: Virtual device temp1: +89.0°C (crit = +105.0°C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +85.0°C (high = +84.0°C, crit = +100.0°C) Core 0: +85.0°C (high = +84.0°C, crit = +100.0°C) Core 1: +85.0°C (high = +84.0°C, crit = +100.0°C) Core 2: +84.0°C (high = +84.0°C, crit = +100.0°C) Core 3: +80.0°C (high = +84.0°C, crit = +100.0°C)
另一个“dmesg”输出：
[ 993.126316] intel_powerclamp: Start idle injection to reduce power
突然，loadaverage上升，我得到了“顶部”：
3372 root -51 0 0 0 0 S 54,8 0,0 1:04.68 kidle_inject/0 3376 root -51 0 0 0 0 S 54,8 0,0 1:09.30 kidle_inject/4 3378 root -51 0 0 0 0 S 54,8 0,0 1:10.24 kidle_inject/6 3374 root -51 0 0 0 0 S 54,5 0,0 1:08.29 kidle_inject/2 3379 root -51 0 0 0 0 S 54,5 0,0 1:10.29 kidle_inject/7 3375 root -51 0 0 0 0 S 53,1 0,0 1:07.95 kidle_inject/3 3377 root -51 0 0 0 0 S 49,8 0,0 1:06.50 kidle_inject/5 3373 root -51 0 0 0 0 S 47,2 0,0 1:02.87 kidle_inject/1
几分钟后，loadaverage恢复正常，温度下降了一点点，但14分钟后，温度再次boost：
acpitz-virtual-0 Adapter: Virtual device temp1: +87.0°C (crit = +105.0°C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +84.0°C (high = +84.0°C, crit = +100.0°C) Core 0: +80.0°C (high = +84.0°C, crit = +100.0°C) Core 1: +84.0°C (high = +84.0°C, crit = +100.0°C) Core 2: +80.0°C (high = +84.0°C, crit = +100.0°C) Core 3: +80.0°C (high = +84.0°C, crit = +100.0°C)
关于“dmesg”的消息很多：
[ 1471.283752] CPU4: Core temperature above threshold, cpu clock throttled (total events = 1) [ 1471.283753] CPU0: Core temperature above threshold, cpu clock throttled (total events = 1) [ 1471.283765] CPU1: Package temperature above threshold, cpu clock throttled (total events = 1) [ 1471.283766] CPU5: Package temperature above threshold, cpu clock throttled (total events = 1) [ 1471.283766] CPU0: Package temperature above threshold, cpu clock throttled (total events = 1) [ 1471.283769] CPU7: Package temperature above threshold, cpu clock throttled (total events = 1) [ 1471.283770] CPU3: Package temperature above threshold, cpu clock throttled (total events = 1) [ 1471.283771] CPU2: Package temperature above threshold, cpu clock throttled (total events = 1) [ 1471.283772] mce: [Hardware Error]: Machine check events logged [ 1471.283773] CPU6: Package temperature above threshold, cpu clock throttled (total events = 1) [ 1471.283779] CPU4: Package temperature above threshold, cpu clock throttled (total events = 1) [ 1471.283780] mce: [Hardware Error]: Machine check events logged [ 1471.284740] CPU4: Core temperature/speed normal [ 1471.284741] CPU0: Core temperature/speed normal [ 1471.284742] CPU4: Package temperature/speed normal [ 1471.284743] CPU0: Package temperature/speed normal [ 1471.284757] CPU1: Package temperature/speed normal [ 1471.284760] CPU2: Package temperature/speed normal [ 1471.284761] CPU3: Package temperature/speed normal [ 1471.284762] CPU6: Package temperature/speed normal [ 1471.284762] CPU7: Package temperature/speed normal [ 1471.284803] CPU5: Package temperature/speed normal [ 1473.935935] intel_powerclamp: Start idle injection to reduce power [ 1759.514479] perf: interrupt took too long (2523 > 2500), lowering kernel.perf_event_max_sample_rate to 79250
之后，kidle_inject进程返回并且永远不会消失：
load average: 5,79, 5,18, 3,12
由于笔记本电脑开始冻结，我在Windows上重新启动，令我惊讶的是，在正常运行2或3分钟后，“核心温度”输出如下：
Core Temp截图
OpenSource或专有CPU“驱动程序”也会出现相同的行为。 我也试过“rmmod intel_powerclamp”，但这只是让kidle_inject再次发生，温度仍然很高。
任何帮助表示赞赏。

即使您的房间没有尘土飞扬，我建议您每年至少清洁笔记本电脑中的通风路径和风扇。
有时默认的/etc/thermald/thermal-conf.xml不会很快做出反应。 保存你原来的地方并尝试这个，注意它有一个非常低的阈值温度，只是为了测试。 一旦您对解决问题感到满意，可以将阈值温度提高到更合理的水平，也许是步骤：
