So after researching water blocks for my gpus for a while today I'm thoroughly confused as to what PCB design my cards are.
I have two N570GTX-M2D12D5 both the same design but sources around the interwebs have conflicting messages. Some say its a reference 580 PCB, some says its a reference 470 PCB.
I finally found a picture of what all the confusion is about, there are two version of this card both with the exact same model number. (I have two of the longer 10.5 inch ones)
I'm suspecting the short stubby one is a 470pcb with the vent cut out in the back of the PCB and the longer version is a reference 580 pcb.
Can any experts confirm for me?
