[DonT-FeaR]

hey guys i just bought 3 fans and i tought it would be easy to make them to 4 pin molexs but i have no idea how to .... can some one help please...


2 fans are the same and have a yellow a red and a black and the other

has an rpm 4 pin connection (blue red yellow and black) and a 3 pin with a yellow and a black


tried to cut and shut the 2nd fan a little bit but have no clue any ideas???

For the four pin one, disregard the blue wire, just forget about it. The blue wire is just for supported motherboards to control it. Also, forget about the yellow wires on all of them, those are just to send the fan speed to the motherboard. Connect the red wire from the fan to the yellow wire from the PSU, and connect the black wire on the fan to the black wire next to the yellow one on the PSU. I don't think it really matters which black wire you connect it to.
