Thanks for taking a look at this. I guess that I will just splice them into the hot wire of the fan and see what happens.

Hi, I am new to the forum and I have what I hope is a simple question. I have acquired a couple of simple Thermaltake VR Fan Speed Controllers, which just seem to be variable resistors that fit in a card slot opening on the back of the case. What is weird is that the cable coming off of the controller ends in a 2pin connector that looks like it would fit onto a fan plug on the motherboard. It would seem that to work, that they somehow need to be in-line with the fan, which ends in a standard 3-pin motherboard connector. I dont see how this is going to be able to control a fan. I can plug this into the motherboard, but that would do no good, because then it wouldnt be connected to the fan in any way. I seem to be missing how this is to be used with a standard fan. I have attached 2 pictures of the controller. I suppose that I could splice this into the hot wire of the fan lead, but it seems like there should be a simpler solution. Any help would be appreciated.
