如何使用C ++在Windows Vista Ultimate中控制CPU风扇速度？
我想使用ACPI。
ACPI： b
$ b
您需要了解并使用WMI - Windows系统管理界面。以下是一些资源，可以为您提供从何处开始的线索：
请注意，某些主板不支持风扇速度更改，即使那些主板也不能将此更改为WMI。在最好的情况下，您可能仍然需要检测主板类型，并直接与风扇管理控制器通话。
没有ACPI： >
如果你不想使用ACPI，那么你必须编写自己的代码访问主板上的SMBUS，然后控制风扇控制器芯片。 / p>
查看程序主板显示器，了解如何开始使用的线索。这是不平凡的，因为每个主板和bios是不同的。
How can I use C++ to control CPU fan speed in Windows Vista Ultimate? I would like to use ACPI.
ACPI:
You need to learn about and use the WMI - Windows system management interface. Here are a few resources that will give you clues on where to start:
- SetSpeed Method of the CIM_Fan Class
- WMI C++ Application Examples
- Example: Calling a Provider Method
Note that some motherboards don't support fan speed changes, and even those that do may not expose this to the WMI. In the best case you may still have to detect the motherboard type and talk to the fan management controllers directly.
No ACPI:
If you don't want to use ACPI then you're going to have to write your own code to access the SMBUS on the motherboard, and then control the fan controller chips.
Check out the program motherboard monitor for clues on how to get started. It's nontrivial, since every motherboard and bios is different.
