据我所知，对于某些惠普笔记本电脑，不可能启用风扇控制服务或类似的服务，我正在使用这样的一个。在 kdenlive 中渲染 6 分钟长的剪辑时，sensors读数几乎从未低于 80 度：
在环境温度约为 22 度、正在运行的 5 个风扇冷却板上。
编辑1：
我在 kdenlive 中再次尝试了另一个 18 分钟长的视频，大约花了 11 分钟来制作，并且温度多次上升到 100 度。
我在用着这一。它集成了 Intel HD 530 和专用 NVIDIA。
通常，当我阅读或编写文档、执行 C#/Qt 代码时，它会保持在 35 度左右，而当我观看视频时，它几乎不会低于 45 度。
编辑2：
shotcut如果我在 中使用 GPU 加速而不是在 中并行使用 CPU ，则效果不会那么大，kdenlive在 中渲染相同的 18 分钟视频只需要不到 2 分半钟的时间，shotcut这里是读数快照：
我不知道具体做什么iTCO_wdt，iTCO_vendor_support但如果我启用这些（nmi 和软）看门狗，CPU 温度达到 100 度的频率就会降低！
CPU在平均温度95度的情况下可以运行多长时间？

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):
Probing for Super-I/O at 0x2e/0x2f

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no):
Probing for `National Semiconductor LM78' at 0x290... No

Probing for `Winbond W83782D' at 0x290... No
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):

再次检查相同的 18 分钟视频kdenlive，这里有 4 个快照：
接下来做什么？
答案1
有选择
假设风扇全速运转，手动控制速度不会做任何更好的事情。一般来说，您有以下三种选择：
- 增加热流
- 增加冷却面积
- 减少热量产生
对于笔记本电脑，您对 1 和 2 的选择非常有限。您可能需要检查气流。冷却风扇中可能有污垢。还有一种可能是导热胶磨损了。如果发生这种情况，CPU 会变热，但从设备中吹出的空气却是凉爽的。
我建议探索选项 3。使用CPU频率缩放或者 – 如果存在的话 – BIOS 的超频机制降频CPU。渲染过程显然会花费更长的时间，但系统会保持凉爽。
对于 nVidia GPU，您还可以选择性能配置文件，有时还可以选择时钟速度。
答案2
温度控制是一个广泛的问题，涉及许多设置。
乍一看，你谈论的是风扇控制为了使固定温度问题。您读过这个 wiki[1] 页面吗？
然后，您可以浏览能源管理维基[2] 是起源你的问题。
