I adapted Accelero x2 for my X800XL card But my card has original fan with 2 pin and I think 6 V instead Accelero is 3 pin 12 V fan I connected Accelero to motherboard 12 v case fan but it won't increase rotations following video card temp detector cause it follows case temp detector. What can I do to adapt 2 pin 6v to 3 pin 12 v on my video card?
