Aquacomputer or Heatkiller?

post #1 of 9
Thread Starter 
Hey OCN, I just bought a reference 7970 and need to choose a water block! Couldn't really find any reviews on either of these blocks for the 7970, so I'm hoping some people here have experience with either one or both. i'm sure they both perform quite similarly, cooling both the core and RAM modules, but I prefer the looks of the Aquacomputer backplate. Price is not an issue, it's just I'll go with the Heatkiller if it performs better, but if they're only 1-2 degrees apart I'll go with the Aquacomputer. Cheers!

You can't go wrong with either one, so just pick the one that looks better. thumb.gif

Doesn't matter in the slightest. When looking for VGA waterblocks always go with build quality/reliability and aesthetics. This is because most all modern graphics cards have locked voltages, so if you're overclocking them with watercooling they will always reach voltmax before thermalmax. If ones performs better than the other for cooling, that's great but it doesn't matter. They both will easily keep your GPU cool under it's preset locked voltage.

I'm pretty sure since it's a reference card it has an unlocked voltage(?). I was intending to push it fairly hard, to at least 1.25 volts.

The 7950 and 7970 do indeed have an unlocked voltage.

Phew, that's put my mind at rest. I guess I'll go with the aquacomputer block then, thanks guys!

No. My friend has 3 ref gigabyte 7970s and 2 are locked.

Go with either waterblocks, I've had Aquacomputer Aquagrafx on my old GTX680 SLI, and now I have the Watercool Heatkillers 79x0, both perform as good, and I prefer them over EK blocks, I'd only go with Heatkiller because I personally find them nicer, but the new Aquacomputer blocks are amazing, not sure if they're made for 7900 cards too though, or just the GTX780 and Titan.

Most cards have a tiny bios switch that you can use in that case. Otherwise he should probably be able to flash another bios onto them to unlock it.
