Is this what you intended to draw?

Well, let me explain it in details if you can help me. What I'm trying to do is that I have 15v 2a transformer which I converted and got 24-36VDC. With that I want to use TIP122 and a variable resistor with other components to control the speed of the brushless fan. That is what I intended to do.

That circuit should work.
