Swiftech GPU Waterblock or Nickel EK and WC Questions

post #1 of 14
Thread Starter 
Hi!

SO, I am building my first computer, and also doing my first watercooling system... So far things are making sense, I have been reading nonstop for weeks, and I think I am getting the just of it.

I have 2 Powercolor 6950 2GB, these to be exact.

http://www.newegg.com/Product/Produc...tent-_-text-_-

Now, I have been reading about the new PCB designs on some 6950 boards and how they are not reference. So companies have come out with V.2 versions of their waterblocks to accommodate, is this true for my card? The EK compatibility calculator says that their EK 6970 V2 fits the same model number as my cards, but for the 6970s. Will they also fit on the 6950? As that is not an option from them.

Edit: to clarify, EK says they have waterblock compatible with "HD6970 2GB GDDD5 (AX6970 2GBD5-2DH)" my card is a "HD6950 2GB GDDD5 (AX6950 2GBD5-2DH)"

http://www.frozencpu.com/products/12...rds.html#blank

Also, I was looking into other options. How well do the swiftech waterblocks work? They are fairly new, and I read some lengthy threads about the anticipation of them coming out, does anyone know how well they work? You have to buy the heatsinks, and then the VGA block (as you can see on the below ling), would these not work as well as it is not fully watercooling everything? Rather heatsinks on some components, and water on others? Or am I not understanding it correctly. They are significantly cheaper, and all together 2 will come out to 150 vs 230.

Thank you for your help, it is much appreciated.

Sorry can't help directly.

My best advice would be to e-mail the manufacturers directly.

Good idea. I'll figure that one out, unless someone has personal experience with these cards.

Do you happen to know anything about the swiftech waterblock/heatsink?

Different card, but I just recently installed an EK 6990 Nickel Wb and backplate on a Powercolor AX6990 and it fit perfectly.

You need to take the coolers off and do a visual match on coolingconfigurator.com. Don't call the manufacturer unless you want your warranty voided (this is in the case that they don't allow waterblocks). Btw, most makers are not kosher with this. Anyways, after the visual, order the right block. Your cards... off the top of my head will probably use the 6870 blocks, not the 6970 v1 or v2. Revised 6950 2gb cards typically use the 6870 pcb, SINCE that is the revised AMD reference design.

Revised AMD reference 6970 pcb uses the 6970 v2 block! Beware, do a VISUAL match before.

If you do end up with an EK card, I'd advise against the nickle plated version. They are very nice blocks with dealing with temps, but they've had a lot of recent flaking issues exposing the copper below. If I did it again, I'd still get EK (so far until they deny my RMA request) but get the copper version

I don't have any direct advice outside of -> stay away from Swiftech. It's cheap garbage. Even with some reported nickel flaking from EK, I'd still not hesitate to buy whichever EK suits you. IMO, this is happening because people are using different mixtures of biocides and anti-corrosions etc. causing some sort of reaction which ends up getting underneath the nickel plating.

You have to understand that in this hobby, none of the manufacturers nickel plating is going to be absolute industry top-of-the-line. Just make sure to wash out your block before installing it and pay attention to the cleanliness of your loop. Whatever chemical base you use, use less than you think. Much less. It takes extremely little of it + good distilled water to keep a clean loop. Doesn't matter what you use IMO. They all have their + and -'s.

While I agree that generally speaking, EK blocks are top-notch, I have to harshly disagree regarding this comment. I opened my GPU block after a mere 2 weeks running on nothing but Distilled to find I have missing nickle plating. There were no additives in my loop what so ever!

This, and to add to it, the whole pt nuke issue has been debunked.

...and in case someone from EK read my post and will refuse my future RMA request based on me "opening" the card, let me rephrase my statement. I removed my card from the system and can see the exposed copper through the acrylic cover!
