笔记本风扇如何启用最高速的级别

chen05_20 · July 31, 2021, 11:43am

用了一段时间的4k显示器，发现了一个问题，风扇好像不管怎么吃cpu,都无法开启最高级别的转速，正常情况下看一个1080p的电影，win下是可以听到风扇呼的很大的声音的，但是arch下就是一般的风扇转速，要仔细听才能听到声音，而且就算画面掉帧了，风扇也不会加速，感觉这样对散热很不好啊，有什么办法解决呢？

你用 sensors 命令看一下温度？
另外注意一下掉帧的时候是不是 CPU 用满了。看一下内核日志，是不是因为过热降频了。

我这是集显，不知道什么情况下用满，总之cpu到了500%多之后就不行了，然后画面卡住，掉帧

依云 · August 1, 2021, 3:48am

从日志可以看出，你的 Google Chrome 连不上网了……

luxni · August 1, 2021, 4:54am

不是大佬，斗胆回答。

首先，笔记本的风扇一般是不归CPU管的，它被规划到了笔记本的另一个芯片上，它的名字叫EC，它是一个独立于CPU工作的芯片。
具体的控制方式，嗯…，太过于复杂，不懂。

再次，貌似thinkpad的风扇控制在wiki上有写:
Fan speed control for ThinkPad_laptops

仙子大人不是也用thinkpad的么？

依云 · August 1, 2021, 5:02am

是啊，但是我的没感觉有什么问题啊。我也不喜欢风扇使劲转，太吵了。

chen05_20 · August 2, 2021, 2:12pm

驱动4k的显示屏，没有独立显卡的话，确实会很吃cpu，当然这个时候笔记本已经远离自己了，声音大点我还可以接受

依云 · August 2, 2021, 2:27pm

我也4k显示器，UHD 630，挺安静的呀。浏览器播放视频会比较吃 CPU，用 mpv 就好了（开启硬件加速）。

chen05_20 · August 3, 2021, 2:26am

怎么说呢，昨天对比了以下浏览器播放高清视频，win下确实流畅度要比linux下要高，而且除非一些弹幕特别多的视频，win下就没有发现掉帧问题，而二者最明显的区别就是2者的风扇转速不同

依云 · August 3, 2021, 3:53am

你配置了视频硬件加速没有？

chen05_20 · August 4, 2021, 10:39am

没，具体怎么配呢？我主用谷歌浏览器

chen05_20 · August 4, 2021, 12:44pm

额，有点没看懂我显卡是 Intel® Xe Graphics 应该是装intel-media-driver 这个把，完了我应该如何验证我看该视频是硬解还是软解呢？

依云 · August 4, 2021, 1:17pm

sudo intel_gpu_top 看看有没有在使用「Video」功能。

chen05_20 · August 5, 2021, 6:04am

e,好像没有用啊，intel-media-driver和libva-intel-driver 都装过了 vedio一直是0% 是有什么地方还要再配置下么？

依云 · August 5, 2021, 6:07am

ArchWiki 都有写呀。不光要装，还要配置的。

chen05_20 · August 5, 2021, 12:38pm

你好，我先用mpv试了下，发现还是没有启用硬件加速啊,请问是驱动装的有问题么？

你是 wayland 啊。使用 --hwdec=auto 和 --gpu-context=wayland 试试？
