Problem using WMI statements (C# code)

[MrSeanKon]

For example the Win32_Fan, CIM_Fan etc.........
When I use these "references" I don't receive any results.
On the other hand CIM_Processor, Win32_Process etc work and I can post CPU's frequency, the number of current process etc...
I think that Visual Studio 2005 does not implement some WMI statements.
Am I wrong??
Any ideas???

Sorry gentlemen here it is:

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.Management;

public class Form1 : System.Windows.Forms.Form

	private Label label1;
      private Label label2;
	private System.ComponentModel.Container components = null;

      #region Initialization and dispose
      public Form1()
	{
		InitializeComponent();
	}
	[STAThread]
	static void Main() 
	{
      	Application.EnableVisualStyles();
		Application.Run(new Form1());
	}
	protected override void Dispose(bool disposing)
	{
		if (disposing)
		{
			if (components != null) 
			{
				components.Dispose();
			}
		}
		base.Dispose(disposing);
      }
