我每小时收到几次以下错误信息：

硬件规格：

ThinkPad X1 Yoga 2nd
N1NET33W (1.20 )
Intel(R) Core(TM) i7-7600U CPU @ 2.80GHz
Production date 2017.11

软件：

Distributor ID: Ubuntu
Description:    Ubuntu 17.10
Release:        17.10
Codename:       artful
Linux 4.13.0-36-generic #40-Ubuntu SMP Fri Feb 16 20:07:48 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

个人简介：

我在BIOS设置中将电池和交流电都调至性能模式，并且BIOS已经更新到最新版本。

问题是什么

问题是CPU温度达到了一个相当早的阈值，大约在75°C左右，即使CPU允许达到100°C。温度从未超过85°C。因此，CPU的功率被迅速降频。

我不知道是否存在制造商硬件问题，比如散热膏不足，或者这是与软件相关的问题。在将其送给联想之前，我希望确保这不是一个自己制造的问题。

统计数据

当我运行压力测试时

stress -c 4 -t 300

错误信息几乎立即发生。

i7z给出以下输出：

正如所说，它从未超过85度的温度，但是CPU却被限制了。显示以下输出

Core 1:        +58.0°C  (high = +100.0°C, crit = +100.0°C)

但是高设置可能没有任何效果。

热管理软件（thermald）。

所以我对热管理软件进行了一番调整。

这是我在这里找到的调整配置：

<?xml version="1.0" encoding="UTF-8"?>
<ThermalConfiguration>

         </CoolingDevice>
      </CoolingDevices>
   </Platform>
</ThermalConfiguration>

这没有真正的区别，但至少我可以看到阈值设置（最后几行）：

最后的想法/问题

是否可以设置CPU温度阈值？
是否需要设置，还是与BIOS/硬件有关？
我的硬件（导热膏）可能有问题吗？
或者我可能完全分析错了什么？

更新 #1

在深入研究这个主题并阅读了关于Intel CPU降频的几篇文章以及其他操作系统和内核遇到类似（或稍微不同）问题的帖子之后，我得出结论，我的笔记本电脑可能并没有像我想象的那样表现异常。

虽然内核消息仍然很奇怪，但原因可能是错误的内核printk级别或其他什么。当我的CPU包温度约为+52.0°C，CPU频率只有1200MHz时，我也会收到这些消息。这根本没有任何意义。

当我用压力测试测试我的笔记本电脑时，我可以看到错误消息，但实际上CPU并没有被限制。

如果我只测试一个核心，我可以获得最大的3,900 MHz的Turbo Boost速度。

测试所有4个核心会将最大频率降至约3,300 MHz。

这是预期的行为。

所以我会把这个问题放在一边 - 除非这里有人能够提供更多的内部信息。

更新＃2

系统更新后没有变化：

所以我最后的假设是日志很有可能是伪造的，或者日志级别配置错误。因为我的笔记本电脑工作正常，也没有被限速，也没有过热。

不过，如果有人有什么想法可以解决这个问题，请随意回答 :-)

我仍然收到阈值限制的消息。

更新 #5

在全新的19.10安装中得到相同的结果。

我刚刚发现一篇帖子，说这个问题甚至在全新的X1 Extreme 2nd Gen上也没有解决。

为了那些考虑购买我所拥有的笔记本电脑的人，以下是我面临的一些问题：

- 触摸屏无法正常工作 - 指纹识别不起作用 - 休眠只有偶尔成功 - 切换不同的工作环境（办公室和家庭办公室）通常由于图形问题而无法正常工作 - 多显示器普遍存在许多问题 - 即使有大量可用的内存，硬盘交换仍然发生 - kscreen和xrandr存在各种一般性问题

所以，我想我现在会放弃，转向惠普或戴尔。对于一台价值约2500欧元的笔记本电脑，我真的不想遇到这些问题 :-(

我现在既无言以对又懒散无精。我猜我以后就不再查看我的日志了 :-( 案件结束。

虽然我已经试过了提到的工具，但这篇文章仍然是一篇很好的帖子，对热力学主题提供了一个很好的概述！你提到了Powerclamp的阈值为85摄氏度。你能弄清楚这个值是否可调吗？ - Christopher Will

我认为可以通过 tlp 配置文件进行调整，但我从未更改过。安装了 tlp 后，我的过热问题都解决了。 - WinEunuuchs2Unix

很遗憾，这些文档中没有提到与温度相关的任何内容。您可以在此链接找到有关TLP配置的更多信息：http://linrunner.de/en/tlp/docs/tlp-configuration.html。 - Christopher Will

不幸的是，如今的ThinkPad与几年前完全不同。它们似乎被设计成在几年后就会磨损 - 我有一些仍在使用的ThinkPad，所有的T6x都处于完美状态，而大多数使用了2-3年的T4xxs则出现了各种过热问题，比如银膏蒸发。这些问题要么是CPU或GPU过热（在高强度3D使用下），要么是各种机械问题。我肯定会寻求切换PC硬件供应商。 - Pawel Debski

1@PawelDebski 谢谢，但请记住我的笔记本电脑现在不超过9个月。 - Christopher Will

@ChristopherWill 你最终做了什么呢？ - L0j1k

@L0j1k 我已更新我的帖子，我在18.10版本中也遇到相同的问题。所以，嗯，我可能只能接受它 :( - Christopher Will

可能是联想的一个bug，这个github补丁可能会为您解决问题：https://github.com/erpalma/throttled - WinEunuuchs2Unix

还可以通过直接查看温度来验证传感器是否损坏：

paste <(cat /sys/class/thermal/thermal_zone*/type) <(cat /sys/class/thermal/thermal_zone*/temp) | column -s $'\t' -t | sed 's/\(.\)..$/.\1°C/'

。在我的设备上，最后一行温度 x86_pkg_temp 73.0°C 是合理的。 - WinEunuuchs2Unix

@WinEunuuchs2Unix

我已经创建了一个答案，以便讨论您提出的erpalma的限速工具。

我已经玩过这个工具一段时间了 - 包括几次系统冻结 :) 不幸的是，我还没有找到适合我的系统的正确配置。但是这个工具确实对我的系统产生了影响。这是我第一次看到真正改变限制/温度行为的东西。

没有这个工具，我的CPU温度从未超过85°C。一旦我安装了这个工具并启动了服务，我可以看到在压力下温度上升到98°C，核心频率约为3300MHz（而不是3187MHz）。

erpalma推荐了s-tui工具，我也强烈推荐。

1. 在安装所提及的油门服务之前 2. 在激活服务后

我会监控我的系统几天，并会回报情况。暂时先谢谢！

- Christopher Will

我今晚会安装这个工具。谢谢你的信息！ - WinEunuuchs2Unix

之前的回答都没有起作用，但是SuperUser上的这个回答给了我一个想法，去寻找相关的BIOS设置。

我在我的联想E590 Ci8 BIOS中禁用了速度调节功能，这解决了我的问题，以上的错误都消失了。 编辑：真正的解决方案 我正在安装ARCH Linux，在安装的过程中遇到了这个问题，通过安装最新的英特尔处理器微码来解决。

当日志显示温度超过阈值时，那一刻的温度确实超过了阈值（95摄氏度）。英特尔CPU具有短期的Turbo Boost功能，可以在非常短的时间内（不到1秒）吸取大量功率。如果监控使用1秒内的平均温度来测量最高温度，通常无法反映出真实情况。这对硬件来说并不好，但这是为了使CPU更加响应而做出的努力。

评论 #18 说：

try running thermald in a window from command line.
systemctl stop thermald
#thermald --no-daemon --loglevel=info
Then do what triggers this, and attach the output of the above command.

如果您认为这个错误报告适合您的情况，您可以订阅电子邮件通知。

在我的机器上，我无法复制加载了thermald和tlp的问题。我打开了五个终端，并在每个终端中输入了以下内容：

while true ; do : ; done

发生的一切就是五个内核以100%和3100 MHz运行。没有出现任何限制，但它确实使两个笔记本电脑风扇以低速运转。通常在Linux中它们是关闭的（或者至少我听不到它们）。系统温度为88摄氏度，键盘仍然可以响应并输入这个答案。客厅感觉有点暖和...
