How do I fix my GPU?
It works fine, except for the fans and lights, and it seems like it's only the 12V supply that is dead. I bought it like this, and I don't know the history.
I tested the fans with a separate supply and they work fine. Plugged a fan into the gpu but with the 12V wire pulled out of the plug and fed from an external supply and I was able to control the fan speed from the OS.
I tested the lights with a tarduino, and they work fine too. There's an MP1475 step-down converter on a daughterboard going to the LEDs, so I assume that is supplied by the same 12V supply as the fans.
I tried doing some research, but everything I find is just MUH POWER PHASES.
The fans connect at the top, and the lights on the right. More pics here:
