據我所知，某些惠普筆記型電腦無法啟用風扇控制服務或類似服務，我正在使用這樣的一個。在 kdenlive 中渲染 6 分鐘長的剪輯時，sensors讀數幾乎從未低於 80 度：

在執行 5 個風扇冷卻甲板上的環境溫度約為 22 度。

編輯1：

我已經在 kdenlive 中再次嘗試了另一個 18 分鐘長的影片，製作大約需要 11 分鐘，而且溫度有幾次上升到 100 度。

我正在使用這個。它是集成的 Intel HD 530 和專用的 NVIDIA。

通常，當我閱讀或編寫文件、執行 C#/Qt 程式碼時，它會保持在 35 度左右，而當我看影片時，它幾乎不會低於 45 度。

編輯2：

shotcut如果我使用 GPU 加速而不是 CPU 並行，它不會做那麼多kdenlive，渲染相同的 18 分鐘影片只需要不到 2 分半鐘shotcut，這裡是讀數的快照：

我不知道實際上做了什麼iTCO_wdt，iTCO_vendor_support但如果我啟用那些（nmi 和軟）看門狗，CPU 溫度達到 100 度的頻率似乎會降低！

CPU 在 95 度的平均溫度下可以執行多長時間？

編輯3： 執行sensors-detect

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):

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 `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' 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):

再次查看相同的 18 分鐘影片kdenlive，這裡有 4 個快照：

接下來做什麼？

有選項

假設風扇全速執行，手動控制速度不會有更好的效果。一般來說，您有以下三種選擇：

1. 增加熱流
2. 增加冷卻面積
3. 減少熱量產生

對於筆記型電腦，您對 1 和 2 的選擇非常有限。您可能需要檢查氣流。冷卻風扇中可能有污垢。導熱膠也有磨損的可能。如果發生這種情況，CPU 會變熱，但從設備中吹出的空氣很冷。

我建議探索選項 3。使用CPU 頻率縮放或（如果存在的話）BIOS 的超頻機制來降低CPU的頻率。渲染過程顯然會花費更長的時間，但係統會保持涼爽。

對於 nVidia GPU，您還可以選擇性能配置文件，有時還可以選擇時鐘速度。
