Yeah space will be tight pelting two cards in SLI, having said that people have phased both so I'm sure there will be a way around it. What cooling do you have on cpu? Two pelts will really heat up your water - what will the rest of your w/cing loop be? Also don't the 6800 cards have cold boot problems.

Cooling for my 6800GT's is taken up by Aquarius 3 with added black ice 80mm rad - effectively 2x 80mm rads in the thermaltake box.
I dont think that will be enough for Pelts and there is not a lot of room to play with on the DFI set-up. In fact I dont think you can fit 2 ultras in the space provided without going to a watercooling set-up.
Thats where the ASUS board really shows off - that real estate between the two cards come in real handy when looking at cooling, I don't know how they perform now but my experience with the first batch made available i January this year was less than desireable.
Having said that I am thinking of using EXOS2 as my next upgrade which would be good enough for peltier cooling.
Am I right in assuming you need a dedicated PSU for the PELT's?
The other question is of course, are they good enough, from a reliability point of view for 24/7 cooling?
Is condensation an issue?

I dunno, lets use my bits of kit as an example:
1x FX55 @ 12x268 1.75v
1x NF4-SLI-DR 326 BIOS
2x 512MB BH5 Ram @ 268 3.6v
3x 120mm fans
2x 60mm fans (PWM MOSFET and RAM MOSFET)
1x80mm fan (extra airflow into PSU)
1x Mach2GT
2x 6800GT's 448/1180 (which would be higher using pelts)
3x SATA drives
1x Watercooling rig with 2 12v pumps and 3x 80mm fans
1x PC&P 510 SLI PSU
1x Optical drive
I don't know enough about Peltier cooling and don't feel that confident powering 2x 80w pelts as well as all that kit off the same PSU. Would a 51/4" bay PSU which has the high amperage to cope with peltier power be recommended instead of all that load on the PSU?
It would be interesting to know if anyone has already done this and let us know what they have achieved.
It's an interesting concept and could be the final part of the upgrade jigsaw to get up into the top 5 benchers in the all important hall of fame
Of course there's always the opportunity to use Phils 850w beauty, or at least thats what I could tell the missus when I tell her thats my next upgrade
Finally lets talk which parts to use:
What Pelts with which watercooling block for 6800's?
What insulation would be required and where would you need to put it?
Can it be insulated in a way so that it can be taken off (with no trace evidence) in the event of RMA?

I would deffo invest in another psu, something like a meanwell. I also wouldn't bother with an 80w pelt - go with 172W pelt.
Get something like a dual heatercore or thermochill 120.3 rad.

I thought the same.
Just checking out whats available for the pelt VGA blocks - the DD Maze unit looks as though it'll stick out too far with the DFI SLI and interfere with the other VGA card and for the bottom card it may interfere with my Audigy 2 ZS sound card.
Any ideas?

I have sked Phil he says pcp 510 sli can cope with 2x80w pelts.I,ve looked at adding the second power supply but it thows out a lot of heat meaning you need to start cutting blow holes in your.And after last time i tried it i don't fancy that as well you know.You have to use neoprene and dieletric greese.
You can find some examples of how to attach them,dangerden do a complete kit with block,pelt,greese and pre cut neoprene but it looks a bit fat.
Size seems to be the main issue but they have brought out a slim line version.But if its thin enough now thats the million dollar question.

I really wouldn't bother with an 80w pelt I doubt it would improve your clocks over standard water and could make it worse.
I don't think there will be any pelt+block combo's out there that will fit on the dfi board you've have to make a custom unit of some description.

I see your point with Dangerden stuff it could interfere too much with the other cards in the system, especially with 1/2" tube and because the pelts already stick out a fair bit before you fit the block.
Phil may be right about the PC&P PSU with 80w Pelts, but lets not forget all the other hi-end componets that are fully loaded in regard of max overclock and the Mach2 at start up.
I don't know about anyone else, but personally I would not want to risk my rig for the sake of a PSU (been there done that).
Will 80w Pelts be enough for each unit? It's possible they would be on the ragged edge - Toms hardware reviewed the 6800 Ultra at 400/1100 and that soaked up over 85w of power under load - it's fair to assume that an overclocked ultra could pump out more than 80w of heat.
I would expect a pelt cooled system to be running somewhere close to 480/1200 mark so the power drain and heat generated by the extra overclock together with 2x 80w pelts would be added to the PSU
.
Nick has a point, the larger Pelts are gonna handle the the temps well within their own capacity, might even get higher overclock 520/1200 would be nice
.
There are a number of 51/4" exhaust assemblies that you can get to help get rid of the extra heat generated by the TEC PSU through the front panel on the drive bay - maybe blow holes aren't required?
Who says the PSU has to be mounted internally? Maybe Phil can set us up with an external (fully encased) water cooler with a Pelt set-up?
Lots of things to consider - anyone with any experience in this field? Feel free to jump in at any time

Sorry just one more thing, Nick said 6800's have cold boot issues - is that correct? Scrap that I found this on another forum:
There was a myth on internet that NVIDIA 6800 series have cold lock on them. I want to clear this up. So far I have booted my 6800GT @-25c temps and the card booted and worked fine. So there is nothing that prevents you from booting up @-c temps
The only issue with the drivers is that it won’t report correct temperatures after 10c. It will just stay @10c no matter what if you get –c temps. But that is not a problem at all
So no cold boot issues and away we go - hopefully the national grid can keep up with all this juice I am sucking up.
Luckily I never signed the Kyoto agreement

All pie in sky mate we just someone with big enough balls to try it.

apparently xfx and asus caads dont have cold boot issues

It's all good for me with my XFX cards then.
Reference to Scorchio - you are right mate, but its your post and I am just helping out
Unfortunately, I feels my balls moving the way of the stomach.
The addtional cost of what I would consider to be the most effective route, coupled with the fact no-one has yet to prove they fit DFI SLI mobo's makes me want to put this one firmly on the back burner.
It's a great idea, unfortunately with not enough behind it to warrant anymore than just just discussion at this point in time.
Hopefully someone with a little more of an adventurous side will look at this post and think 'I can do that' and take that leap of faith and prove to us all it is possible.
What I want as I am sure Scorchio does do, is to get hold of an piece of kit called 'self contained peltier cooling unit for DFI SLI MOBO's and 6800GPU's'

I agree as tempting as it sounds i don't know enough about pelts and with £600 worth of cards it's a risk i would'nt like to take.

Often worse Ferret, 80W isn't enough, pelt cannot cope, so you have the heat from the card and the added heat from the pelt = worse overclock.
