Get hardware temp from OpenHardwareMonitor

Question

I'm trying to use OpenHardwareMonitor to get a reading on the diagnostics of my hardware. If you've ever tried using OHM you know that there is very little documentation on it yet to my knowledge there is no other open source library that is as accurate and robust.

I've been able to get load and clock speed from the CPU but not the temperature. I also don't receive any information about the hard drive (temp concerns me most).

Here's my implementation, it should return everything it has but so far I only get limited information about the RAM (no temp), CPU (no temp) and the GPU.

CPU Temperature is my most important stat to track.

using OpenHardwareMonitor.Hardware;

namespace OHMWrapper
{
    public class MySettings : ISettings
    {
        private IDictionary<string, string> settings = new Dictionary<string, string>();

        public MySettings(IDictionary<string, string> settings)
        {
            this.settings = settings;
        }

        public bool Contains(string name)
        {
            return settings.ContainsKey(name);
        }

        public string GetValue(string name, string value)
        {
            string result;
            if (settings.TryGetValue(name, out result))
                return result;
            else
                return value;
        }

        public void Remove(string name)
        {
            settings.Remove(name);
        }

        public void SetValue(string name, string value)
        {
            settings[name] = value;
        }
    }

        private static OHW m_Instance;
        public static OHW Instance
        {
            get
            {
                if (m_Instance == null)
                    m_Instance = new OHW();

                return m_Instance;
            }

I've been looking at the source code since it's the only way to get any info on it. It's been a slow process but I'd really appreciate any help.

Answer 1

I had to run this code with administrative priviledges to get all the information I wanted. I added a manifest file that requires the code to run with those. Thank you for all your helpful posts.

Answer 2

I also got stuck with this and I just wanted to share my experiences...

So running this with administrative priviledges is mandantory. Nevertheless it still may not work when running from a networkshare.

The Settings stuff (MySettings) and the cpu strings are not necessary... I just used

myComputer = new Computer() { CPUEnabled = true };

That's all ;)
