c# - 我如何使用 OpenHardwareMonitor 库获取 cpu 风扇速度？

Question

我用 OpenHardwareMonitor.dll 引用了我的项目然后使用此代码创建新类:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using OpenHardwareMonitor.Hardware;
using System.Diagnostics;
using DannyGeneral;
using System.Windows.Forms;
using System.Threading;

namespace HardwareMonitoring
{
    class Core
    {
        public static Form1 form1;

        private static List<float?> cpuSensorValues = new List<float?>();
        private static List<float?> gpuSensorValues = new List<float?>();
        Computer myComputer;
        Computer computer;

        public Core(Form1 f)
        {
            form1 = f;
            myComputer = new Computer();
            myComputer.CPUEnabled = true;
            myComputer.Open();
            computer = new Computer();
            computer.Open();
            computer.GPUEnabled = true;
        }

        public float? cpuView(bool pause , CpuTemperature cpuTemp , Form1 f1 , List<string> myData , float? myCpuTemp , Button b1)
        {
            try
            {
                if (pause == true)
                {
                }
                else
                {
                    Trace.WriteLine("");
                    foreach (var hardwareItem in myComputer.Hardware)
                    {
                        if (hardwareItem.HardwareType == HardwareType.CPU)
                        {
                            hardwareItem.Update();
                            foreach (IHardware subHardware in hardwareItem.SubHardware)
                                subHardware.Update();

                            foreach (var sensor in hardwareItem.Sensors)
                            {
                                cpuTemp.SetValue("sensor", sensor.Value.ToString());
                                if (sensor.SensorType == SensorType.Fan)//Temperature)
                                {
                                    sensor.Hardware.Update();
                                    cpuTemp.GetValue("sensor", sensor.Value.ToString());
                                    if (!f1.IsDisposed)
                                    {
                                        Thread.Sleep(1000);
                                        f1.Invoke(new Action(() => myData.Add("Cpu Temeprature --- " + sensor.Value.ToString())));
                                    }
                                    myCpuTemp = sensor.Value;
                                    //if (sensor.Value > 60)
                                    //{
                                        cpuSensorValues.Add(sensor.Value);
                                        if (cpuSensorValues.Count == 300)
                                        {
                                            float a = ComputeStats(cpuSensorValues).Item1;
                                            float b = ComputeStats(cpuSensorValues).Item2;
                                            float c = ComputeStats(cpuSensorValues).Item3;
                                            Logger.Write("********************************");
                                            Logger.Write("CPU Minimum Temperature Is ===> " + a);
                                            Logger.Write("CPU Maximum Temperature Is ===> " + b);
                                            Logger.Write("CPU Average Temperature Is ===> " + c);
                                            Logger.Write("********************************" + Environment.NewLine);                                            
                                            cpuSensorValues = new List<float?>();
                                        }
                                        b1.Enabled = true;
                                    //}
                                    break;
                                }
                            }
                        }
                    }
                }
            }
            catch(Exception err)
            {
                Logger.Write("There was an exception: " + err.ToString());
            }
            return myCpuTemp;
        }

线上:

if (sensor.SensorType == SensorType.Fan)//Temperature)

如果我使用温度，它工作正常并显示温度。但是一旦我将其更改为 Fan，SensorType 就永远不会 == 到 Fan

如果我正在运行原始的 openhardwaremonitor 程序，它会显示所有内容，甚至是 cpu 风扇速度。

那么为什么在我的代码中它不起作用？

编辑**

忘了在顶部的 Form1 中提到我有:

private CpuTemperature cpu;

然后在构造函数中:

cpu = new CpuTemperature(new Dictionary<string, string>
            {
                { "/intelcpu/0/temperature/0/values", "H4sIAAAAAAAEAOy9B2AcSZYlJi9tynt/SvVK1+B0oQiAYBMk2JBAEOzBiM3mkuwdaUcjKasqgcplVmVdZhZAzO2dvPfee++999577733ujudTif33/8/XGZkAWz2zkrayZ4hgKrIHz9+fB8/Iu6//MH37x79i9/+NX6N3/TJm9/5f/01fw1+fosnv+A/+OlfS37/jZ/s/Lpv9fff6Ml/NTef/yZPnozc5679b+i193//TQZ+/w2Dd+P9/sZeX/67v/GTf/b3iP3u4/ObBL//73+i+f039+D8Zk/+xz/e/P6beu2TQZju8yH8f6OgzcvPv/U3/Rb8+z/0f/9b/+yfaOn8079X6fr6Cws7ln/iHzNwflPv99/wyS/+xY4+v/evcJ+733+jJ5//Cw7/4ndy9Im3+U2e/Fbnrk31C93vrt/fyPvdb+N//hsF7/4/AQAA//9NLZZ8WAIAAA==" },

            });

也许 cpu 的风扇应该有这样的东西，但我找不到。所以我想知道他们如何在原始的 openhwardwaremonitor 中使用它。

试图在源代码中搜索:http://open-hardware-monitor.googlecode.com/svn/trunk/GUI/

但我没有找到如何获得 cpu/gpu 风扇速度。

Answer 1

对于仍在为此苦苦挣扎的任何人，您首先必须在 OpenHardwareMonitor.Hardware.Computer 对象中启用主板:

Computer computerHardware = new Computer();
computerHardware.MainboardEnabled = true;

然后您必须深入搜索 2 个硬件层。
我的意思是:

foreach (var hardware in computerHardware.Hardware)
{
    // This will be in the mainboard
    foreach (var subhardware in hardware.SubHardware)
    {
        // This will be in the SuperIO
        subhardware.Update();
        if (subhardware.Sensors.Length > 0) // Index out of bounds check
        {
            foreach (var sensor in subhardware.Sensors)
            {
                // Look for the main fan sensor
                if (sensor.SensorType == SensorType.Fan && sensor.Name.Equals("Fan #1", StringComparison.OrdinalIgnoreCase))
                {
                    Console.WriteLine("CPU Fan Speed:" + Convert.ToString((int)(float)sensor.Value) + " RPM");
                }
            }
        }
    }
}

拥有 subhardware.update() 非常重要；在那里打电话，否则你只会看到控制类型的传感器(我从痛苦的经历中知道)。

希望对您有所帮助。
