you consider this to be 'balls' airflow, and imply that I don't know what I'm doing?

Interesting ...

Yeah, I'll be posting some benchies ... but this ain't a competition like you've been itching for since the last thread died off

I already know your setup is better.

And I'm really not interested in finding myself convinced in a positive away about quad-sli, truth told, I hope to NOT like it

This Co-Op came from Fry's ... so I got 30 days to play with it, and if I like it better than the my old 295, the sandwich may go on the market

Not to troll your thread any, but that second 295 has multi directional flow which is THE dumbest idea for cooling i have seen yet.

You really need to put a high CFM fan right infront of those cards. The second one (card) is useless here. Those HD cages block all the flow dude. Don't make me show you proper airflow for a multi gpu set-up.

And I know about the whole competition dude. I already stated, that I don't care and just want to see. I am as yet unconvinced that my set-up is actually better.

It looks like the single PCB card (the bottom one) runs about 6 degrees cooler than the sandwich, at least at idle, when in quad-sli. I'll see when I run it alone how it compares one-on-one. This is w/the fan running at only 75% of the speed that the sandwich fan blows, too (which you'll see from a screenie I've got).

I'm not a huge fan of blowing half the warm air into the case, but my cpu temps appear completely unaffected (not even by running quad-sli - although my NB is getting hotter, for sure, with 2x295's in there), and ultimately, if the GPU is running cooler w/o raising other temps up much, I think that new card a winner afa cooling design goes.

RE: your criticism of my cooling ...

The top card (v1 295) gets air blowing into the back of it (where it's intake is) from the 120mm fan (part of an antec 900 hd cage) thats in the lower three slots of the 5.25" drive bay (not in photo except for the fan speed switch). The bottom card (v2 295) gets air from the side 120 (not in photo) that's pointing right at it's intake, as well as the 120 in the bottom of the case that's pointing (almost) right at it's intake.

I don't need the air from the front 200mm fan to cool my cards, it's cooling my HD's and that's just fine.

You don't want too much air blowing at the side of the Sandwich card my friend, because it exhausts air out the side. You want air blowing across the back of it, which is what I have going on with it.

The cpu is cooled by exhaust fans (top 200mm and the rear 120mm), and doesn't break 55C even at 4.0GHz running Lintest at 100% on all 8 threads.

Don't even go there with your 'showing me how it's done' nonsense

I've gotten some benchies done but I'm getting too tired to mess with posting all the screenies to photoshack and editing my post above ... they'll be coming first thing in the AM.

But since I know you're probably dying to know at least SOMETHING about the benches, I'll give ya a tidbit ... on Warhead, my average and max fps is always higher than yours. But you crush me on the (arguably more important) min fps at 4xAA and 8xAA ... but not at 2xAA.

The rest you'll have to wait til morning to see ...

i'll be waiting!

Ok. Not to start a war or anything but by "front" I mean right at the intake side of the card like you stated. I know about air direction, its a noobs domain. It's not really about case temps as much as it is about OC potential and stability as you know with increase in temps, OC stability faulters. With a mighty unidirectional wind, temps keep in check. Side panel fans as you stated are useless unless they are right at the beginning or intake of the cards.

It doesn't get much windier or cooler on air then this.

The old and new GTX 295 dumps about the same amount of air inside the case. The difference is where the air goes. On the new one, of course it goes towards the front of the case. On the old one it goes towards the side panel and rear. On both, only (roughly) half of the air goes straight out the back through the slot bracket vents.

... and he has TWO of them (GTX 295).

Last time I checked heat rises. And the last thing you want is to push air out the front of the card where air is being pushed in. I really hate that design.

That would be part of why I'm perfectly happy to be blowing air at the intake from the side and from below on this particular card.

Not only that, but I'm not about to go buy a new 1200 or something for a setup I plan on being temporary. I really don't have $530 to be blowing on a new card ... I mean, I *do*, but I don't want to. However, if I find this card to be better, I may keep it and sell the old one.

And if I do, I will move three of my hd's to the hd cage in the drive bay so that the front fan can give the new card more air, since it take in air on the bottom instead of the top like the sandwich.

Anyways, I got some more benchies to run here, folks!

Bench on! Enough with the nit picking......

WE NEED SCREENIES!

The natives are getting restless ... okay ... I promise you a deluge of info here in the next couple of hours, just tell SS to quit pickin' on my rig ...
