Did mine the other day with mx-2, dropped the temps a few ° since it was running about the same temps as it was when I got it, but ambient is warmer here now.
I did remember to grab a pic with the stock cooler, giant card had to be the last slot to fit in 4-way sli. The height of the DCuII wouldn't let me use the 4-way bridge, but el gappo showed me how to run it with a bunch of flexible bridges.

I wanted to see how was the TIM 3 months after the previous change.
Here are some pics, and as i said ealier, didnt applied the TIM like a cross, but as a layer. Made a cross this time with a bit more lapping. Unfortunately, a sort of "vein" appeared on one copper pipe, ran out of sandpaper and choose to leave it, as this vein is like on 1mm from the border of the GF 114.





1st lapping, not so clean of the tim


2nd Lapping and "THAT" vein






No more noticeable differences of temps. 30 to 32°C IDLE at 23°C ambient, 38/40°C in Dead space 2, and 66 °C in Bad company 2 ( 1440x900,16 aniso filtering, 16 CSAA, All high, shadow medium, core 900mhz, 1,025V)

Let's see if this is going to work. This is my GTX460 SLI rig, ASUS DirectCU coolers.

thanks for the info and close up shots, really appreciate your time and effort

i think i will get some liquid metal pads for my card. i have the liquid ultra between my 950 and h80, temps have been extremely good compared to the likes of as5 or mx3 i couldn't use the liquid ultra on the gpu because i think it reacts with aluminium, and i think on the DC2 cards, there are aluminium between the copper pipes. but those new metal pads are non-reactive to any metal, so i'm gonna give them a try

still have some some filing work to do on a few vram heatsinks before i can stick them on my 580, right now the vrams are just sitting on the pcb 'naked'

anywyas, will report back with some gpu temps in a couple of days, shame there is no way to monitor vram temps...

2 dcii 570s would be a pretty damn powerful setup!

BUT, i worry about temperature of your primary(first/top) card, because those are 3 slot cards, with your motherboard layout, they will literally be stacked one on top of another..

just a problem i can think of, hope it will work out for you though, let us know what sort of temperature you will get after some games or benches

Im very excited!! Im hoping too absolutely strangle all my games with the setup, its going to be immensely powerful for me! Ive never used a pc as powerful as my rig was with the single 560 lol, so having two 570s is going too be awesome.



As for temperatures, im using a haf 922 case, and i can put two 120mm fans on the side too assist with the airflow, and Ill let you guys know how it cools. According too a review I saw on youtube, the guy had overclocked his one too 930mhz core, and had his fans on 30% and his maximum temperature was 74 - im not afraid too turn the fans up so im HOPING that my temperatures will be fine. I guess if they are not - I could look into watercooling them in the future. Although I havnt actually looked into the GPU block possibility on these cards, I do know that they come with mosfet and ram heatsinks, so I could probably get away with a universal vga block as opposed too a full card block, however water cooling is a story for another day Im fairly confident my airflow will be ok within the two cards, Im pretty sure the actual cooler takes up 2 and a half slots worth of room. If not, maybe I could remove the backplate on the bottom one? Time will tell, but im confident ill be fine

I cant wait too get some benchmark results, and post them up here! I will let you know how my temperatures go too. I couldnt find much information on the internet, because it doesnt seem many people run these in cards in sli (understandable as it would take up 6 pcie slots) so ive just got my fingers crossed.

yeah, you should notice a considerable performance increase coming from a single 560.

i'd be interested to know your temps, 'cause i am considering pairing up my 580 in the 'near'(well hopefully, these badasses aren't the cheapest things around) future. but i would have the benefit of having an 4 slot spacing between the 2 pcie slots i would use (1st and 3rd), so that should help temps a little i guess.

as for your setup, i wouldn't recomment taking off the backplate of the lower card, it's there to support the weight of the card, and to be honest it's not doing a great job as it is in that regard, but i'm sure if you take it off the card's pcb would probably bend like crazy...

sticking two fans on the side pannel will definitely help, so fingers crossed and keep us posted

Well, heres 2x 580s. The 580s and the 570s use the same cooler. Hmm, theses have 1x pcie slot in between them. That sure is a tight fit. My guess would be though - if they exhaust out the back off the case, and the front of the card is covered, it looks like it will be able to suck air out of the sides - because of the huge amount of side ventilation on it. So it might be an extremely tight fit, but if i turn the fans right up on the top one, it should be okay. Can you run seperate fan profiles for the seperate cards?

Looking at that picture, im starting too worry if they will actually fit

I cant believe i didnt think of the fact that the backplate would be there too secure the card! silly me. However if the cards are going too be this close together, im guessing I could simply cable tie them together somewhere too add support - im thinking, cable tying the pcie wires together in the middle of them, too add grip pulling them together, then maybe a cable tie along one of the vents on the right hand side you can see in this photo.

I read that the fans are EXTREMELY quiet, and very very efficiant. Ive said it before but im not afraid too turn the fans right up, So im hoping I can simply turn them up high enough for it too suck air through the sides off the card.

Im getting jittery, thinking about putting my crysis:warhead disc in on friday (hopefully, knowing my luck theyl turn up on saturday or monday) and playing with 16x anti aliasing at solid 60 fps



If worse comes too worse, I will just have too run my PSU in an awkward place, maybe even externally and run the card at the very bottom temporarily, and look for an aftermarket cooler for one of the cards in the mean time. hopefully not, the combo of these in sli look so DAMN SEXY!

not bad, you remembered to get a pic of your card with it's dcii cover! i've updated that to the member's list, kept your ln2 pic there as well.

and 4-way 580s...
