Haf X - 28 degree ambient temperature - COOLING TWO/THREE 680 DC2 TOP IN HAF X CASE: HELP

post #1 of 5

Thread Starter 
Would I be able to keep two of these (or even three) DC2 top editions cool in my HAF X case at these ambient temperatures?

How would I setup the default fan? Side panel intake or exhaust?

I will be changing motherboards to the rampage 4 extreme and am debating whether I should get two or three of them.

I'm NOT SURE if I can cool them or not :\. Please help. I would like to keep them boosted and I would like to overclock them but to do so (and keeping them QUIET IS A LARGE PRIORITY) so should I get only two or should I bump it up to three?




Also how should I set up my HAF X case for optimal airflow.

CURRENT CASE SETUP:

I currently have the H100 in the top as exhaust with two 200mm fans.

I have the back 140mm fan intake (filtered).

I have the front 230mm and the side 200mm fan intake (filtered).

I also have an additional fan modded ghettostyle infront of the PSU as an intake. It doesn't blow much in as my case is close to the floor (a few cm off) but it helped to drop my old cards temperatures by 3-4 degrees on load in a single card configuration.




So basically, will I be able to run three of them quietly and cooly with my high ambients or should I only get two?

Regardless how should I optimize my case airflow.


Thank you very much and +rep to help as it's all appreciated - Jassim. thumb.gif

I would rig the side-panel fan to exhaust.

As you can see, the DCII is an internally exhausting cooler, meaning it dumps the hot air from the GPU into the case.
ASUS-GeForce-GTX-580-ENGTX580-DCII-2DIS-1536MD5.jpg

If the H100 is set up as exhaust, you will be pulling in ALL the hot air from the DCII's unless you make the side panel an exhaust.

I would set the side panel as an exhaust, and put the ghetto rigged fan as intake.

Also, they're triple-slot cards, and the HAF-X only has 9 PCI slots, do you not need a networking card or anything else? Just GPU's?

Also, make sure that the board you're buying can allow three of these to fit, with the correct PCI-Expansion slots lining up..
if I were you, I'd buy two to begin with, and run them together and see if you can use all 9 slots correctly, then purchase the third if you REALLY need it..

And by the way, what card were you planning on buying?

I JUST bought two gtx 680 top editions, arriving in 10 days right when I come back from my holiday which is purrfect.

I will follow your advice.

Just wondering where will the top gtx 680 get the intake air from?

Instead of my sabertooth board, I just bought the rampage 4 extreme as it has better 16x slot spacing, and since they wont run in pcie 3.0 I would like to run them in 16x pcie 2.0 to prevent bandwidth-related problems.

I will probably just stick with two, but I'm powering three screens on DEMANDING games and I like my silence so I guess two is my limit. I'll save the extra cash for the big kepler when it eventually comes.

Thanks a lot.

So side panel fan exhaust, I'll remove the filter then. Bottom fan intake and front fan intake.

Should I place an intake/exhaust fan in the bottom (empty) bays?

Should I place an intake/exhaust fan in the bottom (empty) bays?

Two GTX680's should run three screens fine!

What resolution?

Isn't the front intake infront of the bays, and you're proposing another fan behind the same bays? Unless you have a low RPM fan hanging around I wouldn't bother buying one for it, it wont make a huge difference..
Unless you mean drawing air in from the floor, in which case I could see it doing a bit more good smile.gif


The top GTX680 will just suck air from all around the bottom card, the top card will run a bit hotter, but they should both run at reasonable temperatures, Unfortunately, it's best to use Reference cards in SLI (due to the external exhaust) but it doesn't matter so much..

If you space the cards out a little bit, then the top card will run cooler smile.gif

Thanks for the Rep, also! 34! one left!!

Oh I meant in the 5.25" bottom bays,

I have a large intake fan in the HDD bays below.

I'll see if it helps.

Apparently people have been getting 1280mhz OCs on these so if I can get both to 1300mhz then biggrin.gif.

Edit: My resolution is 1080x1920 surround. I am looking to get a dell 1600p ips panel as apparently they're good for gaming (due to low input lag), look great (h-ips), very high res, 1600x2560, and works with games which aren't as good at multiscreens like BF:3.

But I don't have the table space as it's taken up by three monitors, speakers, my large keyboard and mousepad :\.

No idea how I would be able to move mousepad and keyboard to a different location when I want to switch monitors frown.gif.
