Overclocked System Build With 2600K - Thinking about Liquid Cooling
This is a question from AndrewJ1981:


hey man thanks for all the videos!
i have been watching them quite a bit but i'm still not informed enough to build myself a good gaming system. the problem is that i'm trying not to overspend, but i want a gaming system that will be able to run any game on its max settings. i don't care how the system looks, but i want it to have awesome cooling because my room tends to get pretty hot so i was thinking about liquid cooling, but then again, there are so many options for that that i'm very very confused!
i called your sales department and well, the guy kept having to check with a tech guy about my system build and i didnt feel too confident in his advice so i thought i'd ask you for some help.
i was looking at the vesta 5350OC which is a NCIX overclocked build.
i know it's overclocked at 4.0 GHZ, but i wanted a bit more juice out of there, and all the supporting hardware and cooling as well as case to support that. could you help me please?
this is what i initially built, but i'm not sure how well it will all go together and if you would recommend any changes there.

i would appreciate any help you can give!

thanks in advance!


Right now you've got a very good looking build there. I don't see many things that I would change, but here are a couple of comments:

1. I would think long and hard about whether you want DS cards or external exhaust cards. The HAF 932 is a great case for cooling, but those 580s will output a lot of heat. Lots of consideration should be given to the way you want airflow to work for your system. If you decide to use the CoolIT Eco as an INTAKE (so you're not using recycled hot air to cool the CPU), then DS cards should work just fine and you can use a negative air pressure cooling approach. Just remember that it'll get dustier that way, so you should clean it out once in a while with a can of compressed air.

2. You don't really need an add-in NIC. The onboard NIC is also gigabit. That said, MMO games have been demonstrated to benefit from a dedicated NIC... Hard to say how much of it is smoke and mirrors though...

3. Personally I have a couple of brands that are higher on my list in terms of PSU recommendations. Corsair and Antec come to mind.

Thank you very much for the reply Linus!

1. You are right, I do not want to have to clean the computer constantly! What combination of dual video cards, case (nothing too expensive but that will do the cooling job perfectly and not get too dusty) and cooling would you recommend?
Also, I don't necessarily want a full tower unless you think it's better for my build.

2. If the difference is negligible, the forget it. Thanks for saving me 30$! I don't really play MMO games, only shooters and simulators (cars, hawx 2, etc)

3. Which PSU would you recommend me that will handle my build and won't be too expensive? :thumb:

Linus September 28, 2011 12:07 AM

1. Full tower is probably the way to go for a beast machine like this. My personal favourite cases right now unfortunately aren't that great for dual graphics cards... I'm partial to the 800D, 650D, Fractal Design Define XL (this one's probably not a bad bet actually...), and NZXT Phantom (I think it looks cool. Sue me.)

I know Crazy Russian did a dual 580 build in a Define XL a while back and he used external exhaust cards. Maybe that is not a bad route to go. That case supports the ECO just fine.

2. np. it's what I do ;)

3. Grab an AX850 or an AX1000. I know not everyone will agree with my recommendation. I can hear it now "850W is way too small it'll be inefficient under load", but the reality of it is that your machine will be idling 90% of the time it is powered on, and the bigger your PSU, the less efficient it is at idle.

Check out what happens to power consumption when I put in a 1500W PSU in this video. It's an extreme example, but I feel as long as you're buying a high quality unit that it's better to be at 80-85% use under load than it is to be idling at 5% use.

Thanks man and I'll def go with that PSU! I hate to annoy you with this so let's make 2 scenarios. My goal is to have a computer that will be able to smoothly run any current game at max settings. My best choice without going crazy (like triple sli) was dual 580s but I'm open to a single 590 if that'll do the job too!
So here are the 2 scenarios:

1: Dual 580
Best choice is:
Case: Define XL?
Cooling: What's in my original build or do I need more (fans, noctua, etc.)?
Video cards: The 2 EVGA DS CARDS?

2: Single 590
Best choice is:
Case: 650D, 800D or Phantom?
Cooling: What's in my original build or do I need more (fans, noctua, etc.)?
Video cards: Which 590 card would you recommend and would it need cooling too?

Sorry for all the questions, take your time and let me know what you would personally chose if you could fill in my 2 scenarios please:)

In my opinion I would ditch is 580 DS cards and go with the regular style cards that vent out the back properly.

I would also prefer to have 2 580 cards vs one 590 as it would lead to easier troubleshooting in my opinion.

You could probably stuff all that system into a mid size case but you'll hate ever having to work on the system. A full size tower will make life easier.

Those PSUs Linus recommended are very very nice and I'd rather go with them (and I do.....) over the Coolermaster any day....

I would ditch the DVD burner and just stay with the single Bluray optical drive, then put the $20 to $30 you save on the DVD optical drive and put it towards another 8gb of RAM for a total of 16 (RAM is cheap and if you ever run out it makes your system slow, so it's cheap insurance. Some people will agree and others will disagree with this suggestion)

AndrewJ1981 September 28, 2011 08:30 PM

Thanks Perinium!
Def gonna keep your advice in mind but the system already has 16GB of ram!
Linus, any help on those 2 scenarios?
