I have a FirstD FD9238U12D 12v 1.2AMP fan with newer AMD RADEON logo on the front, works fine in any reference radeon 5k/6k/7k series card with blower style fans. The fan itself works 100%, was bought from a chinese ebay seller for the purpose of replacing broken fans of my own, but never needed to use it. I plugged it into a 12v power supply, works fine.
It appears that one of the wires was pulled loose from the fan's PCB and resoldered back in place at one point, maybe due to haphazard storage, and a nick in the blue PWM wire's insulation, but I can cover that up with some black wire heat shrink.
Can do probably 12 bucks, or equivalent on in BTC according to preev.com, shipped via first class with tracking in USA. International will be on your dollar.
