Set fan speed to C #

Question

I know this was asked before, but I just can't get it to work. I called the following:

using System.Management; using System.Management.Instrumentation; using System.Runtime.InteropServices;

And I tried this (I know this is a pity, but its the best I have found):

  [DllImport("Cimwin32.dll")] private void button1_Click(object sender, EventArgs e) { uint32 SetSpeed( //??? [in] uint64 300 ); }

How to set computer fan speed using C #?

Shouldn't your PInvoke be like this:

 [DllImport("Cimwin32.dll")] static extern uint32 SetSpeed(in uint64 sp); private void button1_Click(object sender, EventArgs e) { SetSpeed(300); }

The C ++ method is also used here. You can put this in a DLL and call it from your C # code
