Water Blocks for CFX 6950s

post #1 of 22
Thread Starter 
I am looking for water blocks for my crossfire 6950s. I am deciding between the XSPC Razor and EK blocks. The problem with the Razors is it seems like no one has them. As for the EK blocks, do I go with Acetal, Nickel, or Nickel+Acetal? I would also get the parallel bridge if I went that route, but am not sure which I would need. I have the P8P67 WS Revolution and am populating the 2 blue PCIE slots. With the 3 slot dual work?

Thanks for your help!

I personally don't have any experience with the FC bridges, but I think you will need the 3-slot one. I would get the EK block or possibly Koolance. As for the Varieties of the blocks I usually get either an acetal (acetal + copper) or the copper (plexi + copper).

I've got the XSPC Razor 6970 block on my XFX 6950 2gb. I absolutely love it, as it does it's job, silence the GPU fan, and give me plenty of room for overclocking. I've got the card shader unlocked and overclocked to 880/1325 which are 6970 speeds, and my 3dmark and some game framerates are now comparable to a real 6970.

There was a thread where a guy tested an EK then the XSPC blocks on his 6950, and found lower temps with the XSPC, but I take most of what I read on here with a grain of salt, though I did appreciate his input. Either way, you'll be happy. I'm hoping to go with crossfire at some point this summer, and if I do, I'll go with another XSPC 6970 block. I'm having my doubts about crossfire though after having so much trouble with setting up eyefinity, so many compatibility issues and whatnot. I feel silly for having eyefinity for only two games (BFBC2 and Just Cause 2).

This is personal preference.. I can say one thing. EK blocks have been having nickel plating issues recently. My two 6950 blocks have already lost a lot of their nickel plating and there is exposed copper. So if this is something you don’t want look for another block or consider the Acetal version.

I would also get the parallel bridge if I went that route, but am not sure which I would need. I have the P8P67 WS Revolution and am populating the 2 blue PCIE slots. With the 3 slot dual work?
I use the FC bridges.. they’re very nice and simple to setup. If you motherboard does not support 16x on the top two ports you will need a 3 slot. The 3 slot will work just fine just make sure you buy the bridges for the cards and the “blank” bridge.

If you're going to be overvolting your card go with the EK block, the Razor block is nice but it doesn't do that great a job at cooling the VRM's.

Out of my EK & Nickel experience I would recommend you to stay away!
I know that only because there have been some incidents with EK Nickel products it doesn´t necessarily mean every product is affected but still.
It is a fact that EK has had a history of using low quality material for a vast number of their blocks without admiting or acknowledging their error.

Read this review, it drove me to buying the RAZORs, And it cooled the VRMs on my 6950's just fine even with the 6970 unlock.

That was the thread I was referring to before. I've been surprised by all of the negativity with EK blocks recently, but they've all been backed up with pics, so I'm glad I ended up with the XSPC blocks.

I am leaning towards XSPC but they are hard to find. If anyone knows where I can get them at their usual price, please, let me know

As for the EK, I may go that route since they seem to be available. With the bridge, do you mean get the 3-slot DUAL bridge, or the Triple bridge with the blank slot? I noticed they are not the same distances between the holes.
