C++ code for CPU load and CPU temperature
提问by Sara
I want to see CPU temperature and CPU load in Windows. I have to write it myself not using software like Core Temp. How can I access this information?
我想在 Windows 中查看 CPU 温度和 CPU 负载。我必须自己编写，而不是使用Core Temp 之类的软件。我怎样才能访问这些信息？
I read a similar question to mine, but there was no useful answer:(.
我读了一个与我类似的问题，但没有有用的答案:(。

Recently I have started a similar project. I needed to read the cpu temperature and to control the fan in Linux and Windows. I don't know much about C++ and VS and DDK but I figured how to write a simple kernel driver and a simple program with winring0. In my laptop (and most other) the temperature and the fan is controled by the embedded controller. You have 2 choices, either you can write a kernel driver or you can use a library to access the embedded controller. It's because Windows protect the ec from being accessed with normal user rights. A good (and working) library is winring0 (WinRing0_1_3_1b). A useful program to check the ec and everything else in Windows is the RW tool.
最近我开始了一个类似的项目。我需要在 Linux 和 Windows 中读取 CPU 温度并控制风扇。我不太了解 C++、VS 和 DDK，但我想出了如何用 winring0 编写一个简单的内核驱动程序和一个简单的程序。在我的笔记本电脑（和大多数其他）中，温度和风扇由嵌入式控制器控制。您有两种选择，可以编写内核驱动程序，也可以使用库来访问嵌入式控制器。这是因为 Windows 保护 ec 不被普通用户权限访问。winring0 (WinRing0_1_3_1b) 是一个好的（并且可以工作的）库。在 Windows 中检查 ec 和其他所有内容的有用程序是 RW 工具。

Take a look at Getting CPU tempfrom MSDN forums, there are a few approaches.
从 MSDN 论坛查看获取 CPU 温度，有几种方法。
As to the sane way, you can use Win32_TemperatureProbeclass, that gets its intel from SMBIOS.
至于sane way，您可以使用Win32_TemperatureProbe类，该类从 SMBIOS 获取其信息。
