    So I was looking at the pics I took from the quick undressing of my XFX 6950 1gb cards and looking for some after market cooling when it hit me. The PCB from the XFX 6950 and the PCB from the Reference 6870 look almost identical. I can't see too much of a different except for two Crossfire fingers and a BIOS switch.

    I looked a little harder and there are a couple of very small other differences but nothing that tells me that I couldn't use anything that was designed for a reference 6870 in terms of after market cooling?

    So my question is.... Could you guys look over these pics as well and let me know if you think I should take the risk in ordering a water block made for a 6870 for my 6950 1gb card.

    Here they are let me know what differences if any you might see....

    Looking at this more length might be the only difference.... Maybe this will idea will be stopped before it's begun.... But still an interesting thought... I can't help but notice the striking similarities.

    Still would like other opinions

    Well guys sorry for starting this thread prematurely but I got excited there for a second. You see I am looking for water cooling for my cards and I thought this would work.

    It would with the exception of one thing after more research..... There is whole at upper part of the reference 6870 that is not present on the 1gb models of the 6950's. So this would make it not be able to work. Everything lines up exactly after looking into it except that one whole. So answered my own question..... But if anyone has thought on how to get past this or if it would be safe not to use that one mounting whole please let me know.

    Other wise thread dead :)

    It might not matter. I'd try contacting someone who has seen both blocks. From my experience, Gary at Sidewinder Computers is very knowlegeable and helpfull. He usually repiles to email the same day, if not the same hour. I'd ask him. Although they look to be the same price, so I can't really see an advantage of using one instead of the other.

    its not much of a risk ..... both of them are same "PCB & hole spacing".

    They are quite a similar & if u intend to buy a water block it will fit ur 6950.

    no screws on that hole shouldn't affect performance one bit, and that one hole shouldn't affect the blocks mounting as well...

    Sorry to take for ever to get back to this thread honestly I forgot about it..... But what I wanted to point out here is the difference that I am talking about....

    The first pic is the 6870 PCB.... the top hole is where I am talking about

    2.jpg

    The Second Pic is on mt 6950 1gb card and the missing top hole.....

    3.jpg

    The reason I say it might now work is because of this hole.... and in most full cover water block there is a Standoff looking thing going through this hole on the 6870 water block. That is why I am saying it might not work. Now I know a few people said that I should be able to use it anyway.... If I can use it with out that hole explain it to me because I would love to the experiment for everyone.

    Heres the pics of the 6870 water block reference and the standoff I am talking about....

    ****Edit****

    After further examination maybe I could just leave this hole unscrewed considering this standoff will not travel through the PCB. I wonder then if it would still allow enough pressure to attach it to the card with leaving that one hole undone.

    What about the EK Radeon HD 6870 VGA Liquid Cooling Block

    You know you bring up a good question...l I guess it depends what the back plate looks like. If it is just screws that mount into it holding it on.... then yeah maybe it would work.... otherwise it all depends if that standoff towards the back will cause a porblem. Right now I am using Swiftech MCW80 Universal blocks.... but I always wouldn't mind going for a full block.
