Topic: Questions about cooling, et. al.Posted: 10 Nov 2011 at 5:54pm |

I just discovered DS and I like the flexibility that is offered. I'm hoping to get some input on the specifics before I attempt to build a configuration. Let me outline my usage and constraints first.
I play BF3, TF2, MW3, etc., so good frame rate and video quality will drive this build. I don't really need a lot of storage space, so no need to have monster drives. I would also like a triple monitor system (3D not necessary). -Budget: Open -Available width for case: 9.5 in. (I have a niche in my home office desk that's this wide. This is a preferred constraint, but not mandatory.) -Video cards: 2 X GTX-590 (SLI), no overclocking -Monitors: 3 X 24in. Here are my questions/concerns: 1. Given my case width constraint, will I run into cooling problems with an airflow solution? It looks like on the cases offered here the inflow is from the side and outflow is on top. The front and top are pretty open in my location, but the back faces a somewhat enclosed, albeit larger space. Is a small clearance on the inflow side adequate? For reference, the room temperature is kept at 72F. 2. How hot it "too hot" for a 590 SLI setup or for that matter video cards in general? At what point do I need to consider water cooling? If WC is recommended then should I only WC the GPU, the GPU and CPU? I would prefer to stay away from WC, especially since I don't plan on overclocking. However, I do want to run ultra settings in BF3. 3. If I get an airflow system and later find I need the additional cooling from a WC setup, is it practical to refit one or should it be built in from the beginning? 4. How large a PSU is needed? I'm leaning towards 1200W. Too much? Not enough? 5. It seems like the max resolution of the 24 in. monitors tops out at 1980 X 1200. If I wanted to jump up to 2560 X 1600, do I need a larger monitor? I'm guessing 1980 X 1200 on a 24 in. is plenty for my purposes, but I'm curious. 6. From what I've read it seems like the i7-2600K is the CPU to get. How much RAM should I get? As previously stated my budget is open, but I don't want to spend extra money for something that won't give me a measurable benefit. Any input would be greatly appreciated, especially on the cooling/airflow issue. Once I get some feedbackI'll go build something and throw it up here. Thanks for your help. |

1. room temp at 72f is great, however putting the case in a closed space can create a higher ambient case temp, if this happens you could have high load temps.
here is the deal you want a tri sli setup (forget the quad sli 590, we will get into this later), and for that you are talking lot of heat when underload, you gonna want good air flow, best case scenario IMHO is when you have the front fan bring in air, side fan bring in air and blow direclty over gpus, now we know heat rises, so you want the top fan to suck it up and help it get out, also in the rear towards the top, there is another fan sucking air out, for best airflow that is what you want. If the whole system is under lc, its a little different but not too different since you still got rads with fans on them. 2. ok first you do want oc on the cpu, cpu is the brain of your system and ocing it is like making your brain work 10 times faster, and you don't need lc for oc. now you don't want 590 sli, 590 is dumb card to begin with from every aspect, on top of that quad sli 590 gets beat by tri sli 570/580. temps for cpu/gpu over 85c is considered hot, 85c is the start of the red line. lc is not a necessity, its a luxury, if your room temp is at 80f or higher, both air and lc can't help you, they both use fans to help with heat exchange and blowing 80f air is not gonna be help either way. 3. you can always setup lc in any system, of course with anything its easier to do it from the beginning, but again lc is a luxury and not something that can help you if your room temp is above 80f, blew 80f air cooling will go great so no need for lc. 4. for tri sli you want the corsair 1200w. 5. ok hold on, you said you gaming on 3 x 24", three 24" monitor together have a res of 5700 x 1200, but at this question you make is sound like you gaming on one monitor, if that is the case we need to know. your res is purely dependent on the native resolution of the monitor for 2560 x 1600 res you looking at a 30". 6. for gaming 8GB is more then enough, I will make a config for you once I have all the info I need, don't worry about what to get, leave that to me. Having said that the 2600k is a great cpu but its on the p67 platform, this platform can't do tri sli correctly, there is a new platform and cpu coming out this month, the highend platform of SB, p67 is the mid grade platform of SB, with it comes a new cpu that is 6core and will be king for this year at least, and the x79 platform/mobo that can do tri sli correctly, should we realize that you do need tri sli after I get all the info, then you should wait for the new platform, the 6core you don't need for gaming tho. now to give you the most performance for your money, we first need to figure out what res you gonna be gaming at, so A. are you gonna be gaming on three 24" at the same time, or are you gaming on one 24" or are you gaming on one 24" but like to go higher res on a 30" or are you gaming on three 24" and like to replace them with three 30"? once we have that info, I will know what kind of power it takes to max it out, then I can tell you what you need to do that.

1. It looks like the cases you offer (except that big square one) will fit in my little niche. If it runs too hot I can move it to a more open space. That's just not my preferred solution. I just want to make sure get enough cooling, but if the wider case will insure it then OK. 2. I didn't intend to OC the CPU for reasons of heat and reliability. I'm also not married to the 2600K. Frankly, I'm not up on all the various CPUs offered by Intel anymore. I"m just looking for the appropriate processor to support the GPUs. The tri SLI 580 setup sounds great. Let's go with that. 3. Sounds like I can forget the LC. If it's not necessary then I don't want to waste money on it. 4. Ok whatever is necessary for the PSU. 5. My intent is to run 3 X 24 in. monitors in BF3 at the same time. I saw this setup and it has great situational awareness. For that monitor size I'm assuming I don't need any higher resolution, correct? 3 X 24 in. takes up a lot of space and I don't think I have room for 30 in monitors anyway. 6. 8GB at whatever speed makes sense. 1600 maybe? You call it. I would also like to go with a 256GB SSD and 500GB HD. I realize that's a bit large for the SSD, but I'd like to load up several games onto it for reasons of fast loading. I don't think a 128GB SSD will be enough. A single BD drive should finish it off.Edited by BF3Addict - 10 Nov 2011 at 8:10pm |

Hey BF3Addict,
if youre not going with liquid cooling you're going to want a HAF X case (Dreadnought). it has the best airflow. (its what my system is in, its great). The case is exactly 9.5" wide, but should have space left on one side as it has a side fan that helps cool the gpus. i also have a 2600k overclocked to 4.5 GHz and have never had a stability issue. if you're air cooling you're going to want ether the Nactua or the A70. the Nactua is marginally better. i dont know about the video cards. good luck! BF3 is a great game and what ever system you get will make it even better. |

1. with tri sli you gonna have lot of heat when under-load, so you better have lot of room for teh case to breath.
2. there is no heat or stability issues with oc, its an issue when people that dont' know what they are doing act like they do and mess things up, but when you have it done here its fairly mild with good vcore and load temps and stable, this is a must and the thing that makes the most difference in over all performance of pc. Ok so you want to game at 5760 x 1200, for that setup I highly recommend tri sli 570 2.5GB it will give you better performance then tri sli 580 1.5GB, and to be honest you get anything else and the difference is not worth the cost, I would even recommend going dual sli 570 2.5GB first and then adding the third card later yourself if you are up for it. we need to wait for the x79 platform to come out this month so I can config a system for you with it. but to give you an idea, for tri sli you want a case with great airflow thats the haf x, ram will be like 8GB 1600MHz, 1200w corsair psu, tri sli 570 2.5GB, a70 or noctua cpu coolers, intel 320 ssd, and etc. I would not go with a 500GB hdd, we recommend the 1TB black caviar for its speeds, the other sizes of this model don't enjoy the same speeds, but if you don't care for it, then wait and add the hdd yourself, right now the prices of hdds are high due to the crisis happening overseas. |

You've pretty much convinced me to not use my niche, so case size is no longer an issue.
You mentioned the 590 wasn't a good choice. Is this purely a price/performance value issue? The raw specs seem pretty awesome. Looking forward to the x79 release. Edited by BF3Addict - 12 Nov 2011 at 6:19pm |

everything about any dual gpu card is bad, for example dual internal sli 590 gets beat by dual sli 570/580, quad sli 590 gets beat by tri sli 570/580, reason for this is cause scaling in quad is not as good as in tri.
these cards endup running hotter, they go bad sooner, and when one gpu goes bad you have to send the whole card away, with dual sli 570, one goes bad you lose one card not both. I can go on and on but at the end of the day, tri sli 570 2.5GB will give you better performance in high res than quad sli 590 3GB, for one thing the 590 is really stuck with 1.5GB vram, the 570 has 2.5GBvram, etc., etc., etc. Edited by DST4ME - 12 Nov 2011 at 7:01pm |

So it looks like the x79 mobo is out. What is a good configuration for my gaming needs?
BTW, what does the x79 have that makes it a better choice for my build? The most obvious feature is eight slots for RAM, but I know that's not really a driver for gaming systems.

For a core gaming system, you're still better off with P67, but, if you want a high-end workstation based system that can do gaming, video editing, rendering, etc... |

the x79 does tri sli correctly, and for tri monitor you gonna want a tri sli/cf setup, p67 can't do tri sli/cf correctly.

Ok I know this is gonna paint "NOOB" all over me, but I can't seem to get a build going that allows me to pick the HAF X case with the x79, tri sli 570 and so on that was recommended. Which option under gaming desktops do I pick that allow me to pick those components?

Ticket Number: 618599
ask DS to use 2.5GB 570 instead of the 1.2GB ones, they didn't have that option for some reason, I emailed Alex about it. Edited by DST4ME - 17 Nov 2011 at 1:25am |
