What would be a proper loop for this?

post #1 of 11
Thread Starter 
I just added a 6970 to my current rig (signature). I plan to add another one in the near future, which will make for two 6970's. I may also add a third. The temperatures on these cards is not really the issue, it's the fan noise. This sucker is loud, if I put it on 100% I get great temps but it sounds like a jet engine. 60% is about as high as I can deal with, and that results in 80c+ under load which I can't deal with.

I'm thinking water cooling will be able to get me better temps and still be much quieter. I'm currently looking for a case that will support this as my feeble Antec Nine Hundred will not. I'm not sure how many rads I will need, so that is the main point of this thread. How many rads would it take to cool the following configuration to reasonable temps (would like the gpu < 65c under load and cpu < 35c under load). The cpu is optional, currently that has no temp issues at all so I would be perfectly fine leaving that on air if it will remove a dual rad etc. I also don't have anything overclocked currently and don't plan to as I simply don't see the need. If I have enough headroom with the gpus I may oc for gpgpu computing but it's not too high of a priority. Overclocking my CPU is pretty much pointless as I won't see any actual performance increase with normal use, and that doesn't get used for any high computation as the gpus do better.

3x Sapphire Radeon HD 6970
1x Phenom 2 x6 1090t

I would also prefer to put the gpus on a separate loop from the cpu, provided that isn't going to add too much into my costs and it will actually get me a significant benefit. My thoughts, are that with a single loop, the CPU will be getting heat from the GPUs, which will make it hotter than it would be on air. If I see one mention of the HAF case I will shoot someone in the face. I'll figure the case out after as I already have a few in mind depending on what rads I will need.

tl;dr:

What would be the optimal single or dual loop rad config to keep the following below the stated temps at stock clocks

3x Sapphire Radeon HD 6970 (65c)
1x AMD Phenom 2 x6 1090t (35c)

I really couldn't put a budget on it. I already know I'm looking at $400+ for blocks alone on this. I would rather buy higher end or between mid-range and high-end components than low end etc. If I'm going to spend $750+ I'll spend the extra $100 to get components that are worth it.

I am currently building a 3 loop setup because I am crazy. You can do what you want to with one loop provided you have enough rad space.
The H20 cooling is simple, the case is the reason I asked about your budget.

Well the case is really dependant on what I decide to do with rads. That's the point of this thread, deciding on the rads so I can decide on a new case and get the ball rolling . The case is going to be the first upgrade. Then I'll be water cooling the gpu, then I'll add the cpu, another gpu with water cooling, etc. So this will make the budget constraint a bit less as it will be spread out over time instead of all at once.

Very wise of you to check the rad space before you buy a case! Most people do it the other way around. CaseLabs is the best if you can afford it. It will be the last case you buy and it will last for years to come.

Yeah if I were going to spend as much as caselabs wants i'd just get this lol. I don't mind spending a lot on a nice case, but most of these cases are just overpriced. I mean the materials to make the case don't cost anywhere near $100 let alone $350-$450. Caselabs and mountain mods are prime examples of this. Don't get me wrong they're very nice cases, but they're entirely too high price for what you get. Nonetheless, what I'm trying to find out, is what rad config it would take to cool 3x 6970's to < 65c, and a 1090t to < 35c.

I can't comment for MM, but I can tell you that our cases have substantially more than $100 in materials. If it's not your thing, that's fine, but your assumptions are incorrect.

CPU at less than 35 degrees LOAD? is that possible? thats idle status. my i7 920 is idling at 35 right now, actually.

i would say a couple 360 rads, or one 360 and a 2x something. i have a PC a70f (lian li) with a 360 rad in the top (there is basically a space made for a radiator) and i am adding a 280 radiator to the front today so that i can throw a block on my 580.

i owned a mountain mods case, and that thing was actually priced just about right after feeling the quality of the metal. the panels were thick steel.

i am sure that the case labs cases are similar, but if the OP wants to spend 85 dollars on 30 dollars of ABS plastic, by all means he can get a HAF or something. haha
