Default MSI gtx570 water block

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?

I have a EKFC 580 block installed on my msi gtx 570 card and it fits perfectly, my card was bought earlier this march when MSI still went with the reference pcb. Just check the back of your pcb, if it is shorter and has cut outs for vents, it is the newer revision that MSI introduced and is probably not compatible with reference 570/580 blocks. You're completely right, the shorter stubbier card with a different cooler is a 470 pcb and the longer version is a 580 pcb. Like I said all you need to do is flip the card to its back and see if there are cut outs for vents since that's a sure fire tell that it's a 470pcb.

The shorter one is a 470 PCB. The 570's are pin compatible with the 470's, so at launch MSI used a 470 PCB to speed up production (and perhaps use up PCB stock). I had one, and got rid of it before I found out that GTX470 blocks would fit on the shorter card.

If you have the 10.5" card, it should be a ref 570 PCB and be able to take the 570/580 blocks on the market.

Ok thanks. Thats pretty much what I thought.

The EK site said the model was compatible with the 470 block and the pcb they had pictured was definitely not my cards.

I'm looking at picking up two EK-FC580 GTX

Download the EK manual for the FC580 GTX, there's a good black and white picture of the face and back of the cards. It'll be obvious if yours doesn't match.
