如何获得CPU温度? [英] How can I get the CPU temperature?

问题描述

我需要为我正在开发的应用程序收集一些系统信息.可用内存和 CPU 负载很容易使用 C# 获得.不幸的是，CPU 温度并不是那么容易.我曾尝试使用 WMI，但我无法使用

I need to gather some system information for the application I'm developing. The memory available and the CPU load are easy to get using C#. Unfortunately, the CPU temperature it's not that easy. I have tried using WMI, but I couldn't get anything using

Win32_TemperatureProbe

或

MSAcpi_ThermalZoneTemperature

我该怎么做?我想知道作为 SiSoftware Sandra 的监控程序如何获取这些信息...

How can I do this? I'm wondering how monitoring programs, as SiSoftware Sandra, can get that information...

这里是类的代码:

public class SystemInformation
{
    private System.Diagnostics.PerformanceCounter m_memoryCounter;
    private System.Diagnostics.PerformanceCounter m_CPUCounter;

    public SystemInformation()
    {
        m_memoryCounter = new System.Diagnostics.PerformanceCounter();
        m_memoryCounter.CategoryName = "Memory";
        m_memoryCounter.CounterName = "Available MBytes";

        m_CPUCounter = new System.Diagnostics.PerformanceCounter();
        m_CPUCounter.CategoryName = "Processor";
        m_CPUCounter.CounterName = "% Processor Time";
        m_CPUCounter.InstanceName = "_Total";
    }

    public float GetAvailableMemory()
    {
        return m_memoryCounter.NextValue();
    }

    public float GetCPULoad()
    {
        return m_CPUCounter.NextValue();
    }

    public float GetCPUTemperature()
    {
        //...
        return 0;
    }
}

推荐答案

我很确定这取决于制造商，因为它们将通过 I/O 端口访问.如果您尝试使用特定的电路板，请尝试查看手册和/或联系制造商.

I'm pretty sure it's manufacturer dependent, since they will be accessed through an I/O port. If you have a specific board you're trying to work with, try looking through the manuals and/or contacting the manufacturer.

如果您想对许多不同的主板执行此操作，我建议您联系 SiSoftware 之类的人员或准备阅读大量主板手册.

If you want to do this for a lot of different boards, I'd recommend contacting someone at something like SiSoftware or be prepared to read a lot of motherboard manuals.

另外要注意的是，并非所有电路板都有温度监视器.

As another note, not all boards have temperature monitors.

您也可能会遇到从内核获得特权访问的问题.

You also might run into problems getting privileged access from the kernel.
