CTC duel Extruder layer Cooling



So, having been printing with my CTC for a while now, it was pointed out that the main issue with my prints was caused by the lack of layer cooling, I have no idea how I would go about adding the fan, with very little experience with soldering, and a nervous disposition when the thought of opening the machine to add wires and other components, I was wondering what the easiest way is to add an active layer cooling fan to my machine? Im guessing its as easy as getting a battery powered fan and simply placing it targetting the print? XD

Any advice would be greatly apprecieted!!

thanks guys
