sure how many wires does it have ?
4 correct?
sounds like you have cut the end off.
if i remember the color codes do not match . does it have a yellow wire?
if it has a yellow wire try:
the yellow as [pos +] and the black as [neg -]
let me know if it works for you.
Yes there are 4 wires, (black red white blue) i tried every combination and didnt worked. i also reversed the polarity. I think that this fan does not work without PWM controller. i ordered from ebay 10A PWM controller, so in one month i will see 4 correct?
