Heatkiller 7970 Ni-Bi Waterblock Help?

RoEy · 1 Apr 2013 at 16:07

Hi all,

Been out of the 'loop' for a long time with computers but now it's time to do a gpu upgrade. Looking to purchase the above block along with the Heatkiller backplate for it. I'm tempted to buy a 7970 for it but I've heard that the block also fits some 7950 pcbs.

Can someone provide a list of both 7950s and the reference 7970s that this block will fit on please?

I have a copper loop, as in radiator and heatkiller cpu block so will the 7970 block be ok to use as when I read about it, it says "All water carrying parts of the cooler are made from pure electrolytic copper or stainless steel" ? It was just the stainless steel part that threw me a little.

Also, is it worth buying a 7970 over a 7950 or just get 7950 and OC?

Any help will be greatly appreciated,

RoEy

Find the card you want then check EK cooling configurator to see it it needs a 7950 or 7970 block. There is too many to just list them all out for you

No everyone on the Titanic is dead by now.

But yea as above, check ek cooling config and see if you can use reference 7970 or ref 7950 block then purchase what you want.

also the nickel plated gpu block wont react with copper in the loop. Aluminium and copper dont mix, nickel is fine with everything I think

Ok, thanks for the advice.

Looking at this card:

http://www.overclockers.co.uk/showproduct.php?prodid=GX-297-SP

It's labelled as the Sapphire HD 7970 OC BOOST. However, on the ek waterblock config site it's labelled as the Sapphire Radeon HD 7970 OC Dual-X, yet they both have the same manufactures code - 11197-01-40G

Is it the same card or are the two different? It states on ek site that it's a reference pcb design too but on the ram chips, there appears to be some additional covering to them when the stock cooler is removed.

Any help would be great,

I'd go by the MFR code, probably just ocuk's naming that's confusing things.

It's reference design, the extra covering on the ram can be easily removed.

Ahhh right ok. I might get it then as it's on sale at the moment, £40 cheaper than normal. Thanks for your help.

It will be fine as long as your using coolant with corrosion protection (which you should be anyway). By way of comparison, stainless steel is slightly less reactive with copper than the flux used in brass/copper rads. (As opposed to aluminium which is slightly more reactive).
