Well i plugged the Extra fan into the CPU fans plug, and the CPU fan plug is plugged into the molex (Which i did not realize until after looking to see if the CPU plug that the extra fan was connected to was also connected to anything, (Which it turn out was connected to the molex) so i think alls i did was complete the circuit and make a short and thats why the sparks came out? Still too afraid to mess with it untill i know for sure where to plug it into
