post #4071 of 6939
anybody here crossfire the XFX 6870 black edition with dual-fan cooling? I'm probably going to buy two of them in December when I build my new rig. I would like to know how the cooling is in crossfire. I'm pretty sure they'll be okay, but I always like to see numbers beforehand just so I know what to expect. I've already seen one review where the guy used just one and it ran at about 61C.

There was another review I read where the card was at 75C stock under load, but 67C running overclocked. This is a bit of a gap between the two reviews so I'd like further input...

that's the card, in case anybody else would like to offer some insight if they've used this product or know somebody else that has

For that price I would buy the 6870 hawk for a bit cheaper.

Better cooling and overclocking, plus it's got redesigned VRM and whatnot

Obviously, it's going to be dependent on your case cooling. I find case cooling is a major contributing factor to GPU temps. I have the two-fan XFX 6850, which runs really cool (76C at max). But, it runs even cooler if I increase all my case fans from low to high.

From reviews, it appears that the one-fan XFX 6850 is one of the coolest 6850s so I imagine the 2-fan version is even better.

It also depends on your fan profile as well. Video Cards rarely run at 100% fan speed unless you specifically set it up for that. So, if your XFire setup is running too hot, you can always increase the GPU fan speed.

I just might do that. The only big difference is memory clock, and that's not really significant anyway.

I plan on using 7 fans in my HAF 932 Advanced. I plan to take out the top and side 230mm fans and install 3 and 4 120mm, 1200rpm fans in each slot, respectively. There should be plenty of airflow.

replacing those 230mm fans is a good idea I have 3x 120 on top and 4x in the door all 2000 rpm.Another thing you should do is put one behind the bottom card right up against the monitor cables. If your not using reference cards it pulls a great deal of heat out of the case when the cards are at load.I've seen a 5-7c drop in load temps on both cards and there is no longer a hot spot just above my cards.It shown in the last pic.
