我有一台华硕笔记本电脑（X705UDR），并在其上安装了 ubuntu。但是，我遇到了一些负载过热的问题，经过一番调查，我发现，即使核心温度达到 90 摄氏度以上，它仍然会顺利地加速到 3.5-3.6 GHz（这是额定频率为 1.8GHz 的移动处理器），系统过热相当快（约 1-2 秒）。
我曾尝试安装 TLP 来看看它是否能改善问题，虽然它似乎有助于延长电池寿命，但如果我不小心，仍然会出现过热的情况。
我还注意到它有时仍会发生热节流，至少根据内核日志（来自 dmesg）：
[ 2719.863917] CPU0: Core temperature above threshold, cpu clock throttled (total events = 1)
[ 2719.863918] CPU4: Core temperature above threshold, cpu clock throttled (total events = 1)
[ 2719.863919] CPU1: Package temperature above threshold, cpu clock throttled (total events = 1)
[ 2719.863920] CPU3: Package temperature above threshold, cpu clock throttled (total events = 1)
[ 2719.863921] CPU7: Package temperature above threshold, cpu clock throttled (total events = 1)
[ 2719.863922] CPU5: Package temperature above threshold, cpu clock throttled (total events = 1)

[ 2719.864935] CPU0: Package temperature/speed normal
不确定触发因素是什么，但它表明至少可以配置内核以正确执行此操作。我还注意到，在检查温度传感器时，它报告了有问题的高限值：
Package id 0: +49.0°C (high = +100.0°C, crit = +100.0°C)
Core 0: +48.0°C (high = +100.0°C, crit = +100.0°C)
Core 1: +49.0°C (high = +100.0°C, crit = +100.0°C)
Core 2: +48.0°C (high = +100.0°C, crit = +100.0°C)
Core 3: +45.0°C (high = +100.0°C, crit = +100.0°C)
我相当确定（从观察结果来看）crit 是硬件截止温度，但是 high 有点奇怪。这是 Linux 内核用来确定是否进行热节流的数字吗？如果是，我该如何更改它。如果不是，还有其他方法可以配置内核决定降低处理器核心时钟温度的温度吗？我在旧答案中找到了一些声称可以做到这一点的脚本，但如果可能的话，我宁愿不依赖这样的脚本。
作为临时措施，我发现我可以完全禁用涡轮增压。但是，这也会带来严重的性能损失，因此如果可能的话，我希望有一个更好的解决方案。
编辑：作为临时措施，我发现我可以降低英特尔 pstate 的 max_perf_pct 来限制其加速的程度。这限制了峰值性能，但确实解决了过热问题，而不会过多地牺牲持续性能。
