ASUS EAH6970 DCII/2DI4S/2GD5 Watercooling

post #1 of 10
Thread Starter 
Hey everyone!

I have an ASUS EAH6970 DCII/2DI4S/2GD5 and I'm looking to throw some watercooling on it. It's obviously not reference design, so any old 6970 block isn't guaranteed to fit on it.

My question is if anyone has put a block on this card before, and if so, do reference blocks fit? If not, did you use a single gpu watercooling block? How about any cooling methods for the parts around it?

The plan right now is to throw a MCW80 onto it if I can't find a better solution.

Thanks!

Here's a quick shot of the board without the cooler, maybe it will help. This thing is like 90% heatsink!

Sorry for the crappy cell quality.

that would be one of few options you have.
you can also use EK-VGA supreme HF or XSPC Rasa GPU.
But I do think ek will outperform both by a degree or two.

other "hot" parts can be passively cooled by heat sinks.

I hope that helps a bit.cool.gif

Thanks for the hits on the other brands. I'll definitely check them out. I had two extra MCW80s which is why I mentioned them. The EK one definitely looks nice.

What are people using for passive heatsinks lately? I used to have a few of the ones with sticky thermal tape that you would apply to the hot parts.

Main problem is the its not reference, so blocks wont work.
GPU block, would work, but you need to find a way to cool the VRM and the rest of the card.

Thanks, I've pretty much already established that much. I was surprised that the VRM and the rest of the card actually were not touching the active heatsink. The air was simply being blown across them.

Do you have any suggestions?

may i ask why would you want to watercool a dcii card? the stock cooler is not cooling the card properly? or too huge? planning on sli?

anyways, back to the card, like others have said, due to the custom vrms, a reference waterblock just won't fit, but your mcw80 should do nicely for the core itself.

as to the rest of the card, the dcii cards don't have any cooling on the vram chips, but the vrms do have that black heatsink on, might have to get some of those on the vram chips, not sure pure passive will cut it if you plan on overclocking, stick a fan if you haven't already done so on the side of your 902, hopefully it should provide enough airflow to cool the vrams and vrms.

Its just no getting harder to do, as companies are moving towards customs, than reference.

I dont see a reason to WC this card. The air cooling it provides are very good.
other option is to find a reference 6970 to watercool.

The size is my main concern. This cooler on this card legit takes up two slots by itself. Watercooling would allow me to use 2 sata ports that it is blocking on my motherboard as well.

I also just like my things to run cool and quiet. I used to have a 4870x2 but got this card so now I have a GTX480 cooling a i7-2600. Needless to say, the loop has some untapped potential.

Thanks for the link for the heatsinks. I'll get some of those. I do plan on overclocking and I do have a fan in the side of the 902. I also monitor the temperatures of the vrams so i'll know if i'll have any trouble.

I want to water cool my EAH6970s too. Partly because I want to w/c the whole rig. Currently the CPU is. Partly because the damed 6970s run at 90deg. C. Even a game like Portal 2 shows the cards at 99% GPU activity all the time. No wonder it's so hot. My other rig, with a 5870, never goes above 45deg and 50% activity with the same game, same settings.

I think the drivers are screwed. I tried installing the latest right from the ASUS site and get blue screened trying to install 'em.

I tell ya, I've been an AMD/Asus builder for years but I'm right at the point where my next build will be Intel/Nvidia.

I really want to w/c this pair, but what good if the chips will be forever pegged at 99%?
