Well first off, your grammar needs some work
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.

its not fried it still works but the fans dont work when i plug the 3 pins in lol

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.

EDIT: The blue is ganna be your ground, Red will be your 12V and the yellow is your     Tachometric

yes but i dont think you understand .. the white plastic bit with the 3 prongs sticking out dose not work atal

is there anywhere on the underside of the power socket i can solder them ( see pic )

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.
