If you could post a picture of what you have, it may help.Thanks cmon, ah, I should've clarified. I was hoping you could explain how it's done. The thing you use to adjust the temp on mine is just plain black and it looks a bit like one of those lego pieces you use for the axles. I've noticed in other pictures, there seems to be a white capping surrounding.
I was hoping that someone could provide a written explanation of what was done, since I can't gather much from a picture.
