GPU Water cooling, ATI 6870 crossfire?

post #1 of 14
Thread Starter 
I'm looking to install a water cooling system to keep my crossfire setup cool, as the combined sound of both cards at 40% fan speed is driving me crazy.

I've looked in to aftermarket air coolers but none seem to signifcantly lower the sound levels whilst maintaining a decent gpu temperature, so water cooling is my preference.

If anyone can recommend a decent setup, which will be compatible with two gpu's that have only a pci slot between them i'd be immensely greatful. I'd also like to keep it as cheap as possible

thanks in advance. thumb.gif

2 of these : http://www.ekwaterblocks.com/shop/blocks/vga-blocks/universal-vga-blocks/vga-supreme-hf/ek-vga-supreme-hf-bridge-edition-acetal.html and this : http://www.ekwaterblocks.com/shop/blocks/vga-blocks/fc-connection-parts/ek-fc-bridge-dual-parallel.html is what I use with my 6870's.

I don`t recommend investing in WC of such old GPU, better to sell them while they are worth something (130$/piece) and buy new one HD7870 from Sapphire, which has silent operating speed.

Selling the cards and upgrading wasnt an option i'd considered but does seem appealing, is a single 7870 as powerful as two 6870's?rolleyes.gif

Why not put an Antec kuhler 620 on each one, you would get water cooling and great temps at less than the price of two water blocks......

Single 7870 (reference model) is 35% better in BF3 and Unigine benchmarks and in Tesselation tests about 70% better.

I know what are the problems with Crossfire on some games and that terrible microstutering, I have been there with two HD5770. wink.gif
Therefore in your position I would rather upgrade to single new-gen card, than keep up with old ones and spend 150$+ for 2 WC blocks.

You don`t even want to go into draining CF card setup if something goes wrong, or one card has to high temperatures on WC.
Just another pain in the ass.

That is a single 6870 vs 7870. Xfired 6870's are better than a 7870. The 6870's typically scale @ 90-100% To get slightly better performance he would have to get a 7970. I've personally looked into for myself. If you are willing to spend the money get a newer card, but the performance in a single card is going to be ahrd to beat xfired 6870's. I'm going to try and refind my thread for benches and comparison.

I'm really unsure what to do, considering crossfire 6870's are better... at present I get 60-80 fps in BF3 in ultra settings, it's just that the card fans are ridiculously loud, and one cards core temp hits about 87 degrees.

Tbh if you are happy with your cards performance I don't see why you shouldn't Watercool them. They are powerful cards that still compete with the newer cards. thumb.gif

My statements were about single 7870 vs 6870.

I know you are unsure, but sometimes you don`t want to invest 150$ in WC blocks and CF bridge where you could get 260$ from your used GPUS. (This plan is worth at least 410$ of your wallet)
And new 7870 is 330$ with reference cooler (louder) and 350$ with custom cooler(brand specific).

By that wallet I mean you would invest in something OLD, and you will never able to get that kind of money back! OLD WC blocks don`t go low as 1/4 of initial price after generation of GPUs is 2years old.

Those custom cooler models of 7870 are really silent, like MSI lightning or Gigabyte with 3fans.
