Her is what I picked up

That variable resistor will change from 0 ohms to 5000 ohms. And can handle 2W.
You'll need a small "project box" to mount your new dimmer to, and you could get away with crimp connectors, although the soldering job for this need not be pretty! Just clip the 12v+ line going to your fan and insert this pot. (potentiometer.) Drill some holes into your enclosure to let air circulate. CHeck the heat of the resistor after running for a while. If its to hot to touch, discontinue use, and search for a higher wattage variable resistor.
