Well first off, your grammar needs some work :D
Second, There is no picture, Try to fix that please.

Third, It sounds like you reversed the order they go in. I did that once and it sparked a bit.

Whisper fans come with an adapter to work in both the 4 prong and 3 prong xboxs.

Please get a picture of your wiring setup and the chip so I can further help you.

never solder with the box or anything on. it could permently damage you box. if theres a black wire on the 3pin then thats the wire you put to ground and any of the other wires are positive.

You COULD wire your fans directly to the PSU, which would be called the 12v mod because it would run at 12v

Your fans will get louder.
