First time watercooling. Can someone explain the difference between these two waterblocks?

post #1 of 6
Thread Starter 
Hi everyone. I'm looking to watercool the 290x. As of right now, these are the only two waterblocks on the market:

EK Acetal/Nickel
EK Acetal

What is the difference between the two? Which would provide the best performance? Also, does anyone know if Koolance or Swiftech or anyone else is going to release waterblocks? How are EK waterblocks compared to competition? Can I look at results of, say, the 780 across the manufacturers and compare the results?

The only difference is the obvious visual one. One is Nickel plated copper and one is all copper.
As far as performance any difference between the two is far too small to measure.

The Titan / 780 blocks have been tested here;

Whether the results would be the same if the 290X blocks were tested is doubtful but you can at least compare the build quality of each major brand from the disassembled pics.
EK, Heatkiller and Aquacomputer are the best makers by far in my opinion.

Thanks a lot for your reply! That's exactly what I needed.

I have another question. Dose it make a difference if I get a completely reference 290x vs a non-reference that is compatible with the waterblock? Which would give me more overclocking headroom?

It needs to be a reference design with that block. It will not fit a smaller card.

Well, what I'm asking is that there are different cooling solutions for the same exact PCB design. Like the 7970 twinfrozr, the only difference is the cooler and it can fit a waterblock on it since it uses a reference PCB. Would that type twinfrozr, which can come factory overclocked, be be better for watercooling since you'll be able to push it further?

And regarding the copper vs nickel, does it even make a difference in terms of looks? The copper/nickel side of the waterblock will be facing the PCB so no one is going to be able to look at it and tell that its copper or nickel.

A graphics card with a reference PCB is the same as any other, any difference is only going to be luck of the draw.


Copper and Nickel are pretty easy to spot normally.


Not all brands completely cover the front too, Heatkiller and Aquacomputer blocks you can see the difference from the front easily even if they aren't clear acrylic versions.
