570 SLI temps, mobo spacing?

Hey, I have 2 EVGA 570s HD (non reference cooler) in SLI on a gigabyte x58 ud3r. The card are very close together, barely any space. Currently, on bf3 my top card is 75 degrees with the fan going 85% or more. The high fan speed makes me worried the card will start to go plus it's kinda loud. My question, would a mobo with extra space I between cards make a difference? And I mean a worth while difference, since (got a i7 920) and the 1366 mobos are still pricey. If the temp difference is noticeable, any recommendation on boards?

Also, I have a HAF X case, I installed the air duct with a 120mm CM sickle flow fan, is this making it worse since my cards are non reference? They push hot air out the back, could the 120 be pushing it into the card again?

Thanks for any feedback.

put one 570 in the first slot and the second in the last slot. Provided you have a long enough bridge that is.

x8 won't slow the 570 down at all.

75 degrees is not a bad temp for those cards, but yeah using the 1st and last x16 connections (labeled PCIEX16_1 and PCIEX8_2) will work on an X58 board and result in lower temps for your cards. I have that motherboard. The SLI connector supplied with the board is long enough for the added distance.

Also, I have my 680s in that same configuration (1st and last slot). I put them that way after benchmarking them in the 1st and 2nd slot versus the 1st and last slot. I found no difference in gaming performance, but I found a 5-10C lower temp of each card when separating them.

Before I got my 680s, I had 580s on this motherboard installed in the manual-recommended configuration (PCIEX16_1 and PCIEX16_2). They regularly hit the low 90Cs during gaming (which is still within the GTX 580 temp threshold). With the 680s in the manual-recommended configuration (PCIEX16_1 and PCIEX16_2) my cards hit mid 70Cs. With the 680s in the 1st and last x16 connections (labeled PCIEX16_1 and PCIEX8_2), the temps rarely exceed the low 60Cs.

If you consider most socket 1155 motherboards offer 2 8x PCIe 2.0 or 2.1 slots when running SLI and people using them aren't seeing performance decreases in this configuration. So using a 16x/8x PCIe 2.x SLI setup is not a problem at this stage in tech, so you really don't need a new motherboard.

Let me clarify, I have the x58 ud3r not the x58a ud3r.

And yea, 75 isn't too bad but that was also 45min of gaming (haven't tried longer) but I also worry for the fans lol... Curious to know of anyone has experience spacing out there cards and seeing the temps change?

Oh... you have the EX58-UD3R not the X58A-UD3R. I guess I assumed the wrong additional letter from your initial description (I don't have that same motherboard). Your out of luck with that motherboard.

You could get into one of these EVGA Classified bad boys, refurbished but still a 1-year 3rd-party warranty at $180:

Or if you're like me and prefer to buy new, this FTW3 will give you the 16x/8x option at $220 (just saw $180 after rebate):

If I were to spend any more than that, I'd start considering a platform upgrade.

yeah i thought he was talking about the x58a too.

I think even $180 is too much for an x58 board. Unless the noise really bothers you, don't worry too much about the temps. If the fan goes you can either rma the 570 or buy an aftermarket cooler. It's not worth ~$200 just to space out your gpus.

If you have money burning a hole in your pocket then just upgrade to sandy or ivy.

I agree with you guys, another x58 motherboard would be a waste of money... Unless the old one stops working... Even then, probably better to go ivy. To get a new board for potentially better gpu temps isnt even worth $100. Thanks for your input.

Also, I was more curious to see if people actually saw improvements in their SLI/crossfire setups going from cramped to spaced cards.

temps (unless extreme) don't affect performance, so no.

OCing because you have more thermal headroom would be the only way it would increase performance.

Just put your fan on Auto setting and let it be. While 75c is nice, it's actually not the way the card was designed. It was designed to run above 80c and the fan will adjust its speed to reach whatever the engineers designed as the target temp.

On my card when gaming the temp level sits solid and flat at 86-88c. The only variable is how fast the fan runs. Sometimes they are in the mid-60% range, other times as high as 72%, but those temps always stay exactly the same at their designed target level.

really? 88c sounds high for the default fan settings. I don't have a 570 or 580 but most cards i've seen rest in between 70 and 80 in a decent case while running furmark with stock fan profiles.

I'm not saying 88 is dangerous though since many prebuild computers go above that with their crappy airflow so nvidia and amd make sure their gpus can handle it.

I love this review because they use my exact case, an old Antec Sonata:

GTX 580 @ 89c load:

GTX 570's in SLI @ 91c and 89c:
http://www.behardware.com/articles/747-36/report-graphi...

Your 6950 (6970) @ 92c:
http://www.behardware.com/articles/747-20/report-graphi...

The point is there is no way anyone should be complaining about noise with a pair of SLI'ed GPUs at 75c in a HAF X case with the fans running at 85%, which is their maximum. Put the fans on Auto, let the temps rise, and lower the noise levels back down to where they should be. As long as the GPU temps run below 90c, all's good.

Wow, that review's 6970 is a lot hotter than my 6950 when it was stock, even after i unlocked the cores. Maybe Asus sets a higher fan curve?

But i agree with what you are saying.
