I need some suggestions for my loop. Dual-GPU cooling.

post #1 of 9
Thread Starter 
SO I have a 6970 in my loop right now. I just picked up a 2nd monitor cus it was on sale and I'm even thinking of going ahead and getting another one since it was so cheap. For those wondering, it's the ASUS VE249H. It's 189 opposed to the usual 249. Anyways, I want to add another 6970 and I'm gonna wanna stick that in my loop. Right now I have MCP655 pump with the RX360 rad and a 250mm tube res. I'm only cooling a GPU and my CPU. If I add another GPU, will I need a better pump? Will I need another rad? Or another smaller rad? I have the 800D case and have my pump on the very bottom where the PSU goes. I tried to look through the gallery thread to find something similar but there's just so much!

If the rad and pump are sufficient to run CPU and dual-GPU then there's no problem. If I need to add either another rad, pump or both, then that will require some rerouting and new placements. I'd rather go the easier way. OR I can solve this by getting a 6990 or a 590 and keep my loop the same. wink.gif

Here are some pics to get an idea of maybe how I could go about doing this.

you have a big enough rad and res but I would suggest going for a better pump, 1200l/h would be enough with 1/2'' tubing

Hm, yeah. I've got 3/8 ID 5/8 OD tubing now. I do want to change it out cus that purplish looking tubing is supposed to be blue.

Any suggestions on a pump??

Now my next decision will be if I wanna get another 6970 or do tri-fire with a 6990. Real world problems. Haha

That's a liang D5. It works for 2 rads and 3 blocks. Maybe get a second for redundance down the line but not an issue.

Can you get a nice thick 120.1 on the rear?

You can cut the bottom of the case to fit a 240 also if you wish.

Pretty sure you'd be ok with the 360 and an extra 120.

Yeah I was actually thinking I could put a 120 on the rear. I had an H70 there before this so I don't see why it wouldn't work out.

Yes I have the D5 top.

But now I'm trying to decide if I should even Xfire this card or just get a 6990 for my sig rig for 3 monitors and put this 6970 into my other machine.

6970 could probably be pushed further if your going to OC, that and 2 6970 > 6990 just in general. The D5 you have is plenty, I have one running a 360 rad a HF supreme and 2 GTX275 blocks just fine. The single 360 should be fine in push/pull for the extra card, if your only going to do one side an extra rad would be good to add more space to help cool the loop.

Hmm, I'd probably end up push/pull with my current set up then. If I don't HAVE to add any rad I don't want to. I won't be OCing the card(s). I also may wait til BD drops to do all this so I only have to redo this once. Thanks!
