That card seem to have one freakishly huge fan; larger than found on HD 3870 X2. Don't know how badly it's needed?

That had 8800 GT SLI, but we know already that this card will have 2x128SP..so it will not be 8800 GT SLI, closer to 8800 GTS SLI. Geforce 9800 X2 uses 2*G92-450-A2 when 8800 GTS 512 uses single G92-400-A2.

It is needed, the GT and GTS have freakishly SMALL fans (but with a lot of plastic and aluminum wasting space) causing them to litterally burn up. I fried one, and the other I set the fanspeed up from 29 to 52%... and the cover sticker melted off of it when I was gaming.

So, the cooler will be in the middle of a PCB sandwich? Hmmm, at least with the holes in the PCB hopefully cooling will be balanced and better than the 7950GX2.

I have a feeling anyone buying the 3870x2 is going to have some regrets when this card comes out.

Let's face it, if you're willing to spend $450 on ATI's X2 with super noise, why not get super noise from the 9800 GX2 and be much faster, for probably not much more cash.

Is that really a sandwich cooling? That'd be interesting.

The sandwich cooling is interesting, however the simple fact that it needs 2 PCB's is alarming. This thing should have mad power consumption, and that gaping hole in the PCB frightens me. "Not much more cash" also jumps off the page from LTG's post; I can see this thing being announced at $499 and hitting the street at $600+.

Why would it have mad power consumption?
http://techreport.com/r.x/rade...3870-x2/power-load.gif
8800 GT SLI's powerconsumption could be their target.

I don't think that retailers will put that kind of extra price tag on this card since it won't beast 3870 X2 with ease. Some people seem to think that this card needs to cost two times the 8800 GTS 512..but:
1. That cooler won't cost twice the one found on GTS 512MB
2. Those PCB's are simple and won't cost that much; costs from PCB-boards is less than twice (compared again to GTS 512)
3. What kind of profit margings they are thinking? I mean that 8800 GTS 512 have been overpriced card for some time; it would be weird if they wouldn't drop profit margins to stay competetive.
4. There's 8800 GS 768MB which uses artificially crippled G92 (which is more expensive to make than typical G92 found on GTS 512), it also has 50% more vram and some of them even use expensive Zallman-coolers, but still they can sell them with 100?/$150 smaller price tag compared to GTS 512 and make profit.

That fan on GF 9800 GX2 is larger than one on HD3870 X2, which is good.. more air flow with same noiselevel.

That looks like the exact same fan as the one on the Ultra, GTX, and GTS... I don't know what you mean by small fan on the GTS. It's plenty big and does the job it's supposed to without making too much noise. It sounds like you have some serious heat issues with your case.

edit: back on topic. this card looks bad ass. It will be really hard to try not picking one up :)

Attempt at humor? It's hard to laugh at such a pointless remark.

Well it's not the single GPU solution that many are waiting for, but it does look promising!

The cooler looks like it'll do a pretty fair job of pulling heat off the pcbs and moving it.. inside the case. Here's a pic of the slot end. As you can see there are some slots, but I bet most exaust will follow the path of least resistance out the side ports. Aside from the case exausting, I'm betting the cooler will perform well and the fan will not be as loud as some fear. My GTX fan at 85% is quieter than a G92 GTS fan at 70%. Bigger fan motor, slower rpms, less whine.

Two CAPS and one set of PWM's per pcb from what I can see. Curious what the wrap-around copper colored thingy with thermal paste on it is (first pic in OP). Is that a data path? If so, interesting that it needs to be cooled.

Oooh, ooh, someone with few posts said something smart. Lets call him a noob because how many posts you have on anandtech is the only indication of your computer experience! [/sarcasm]

nitro, the entire thing is freakishly huge, but the FAN is tiny... and the heatsink is 50% alumium 50% plastic on top... so its pathetic when it comes to cooling.
Most aftermarket fans feature a much smaller but better placed 100% copper heatsink with a fan twice or three times as big or larger

I'm just not sure you can tell that from those pics... Not that important, really. As long as the card stays cool, that's all I care about.

Only the original run of G92 GT had a small, noisy fan. Second run editions switched to the same larger, lower RPM fan as the G80s and G92 GTS, which is not loud up to 80-85% (depending on how loud your existing case fans are).

9800GX2 fan looks to be bigger than the G80 fans though, with the diamater being very close to the height of the card. The holes on the PCB are also rather large and look as if they expose half of the fan for air intake from two sides. Interesting design, although the custom PCB design probably costs a bit more in the end.

This part will have to be priced close to the X2 though. Core is G92 450 A2, so it might be able to hit higher clockspeeds than the 512MB GTS depending on cooling. If I had to guess, NV is shooting for higher clockspeeds on both cores than the GTS 512MB in order to convincingly beat the X2 and justify being later to market.

All very good points and probably right on target. I'm wondering about oc though. G92 GTS pcb had an extra set of PWM's and CAPs compared to GT. Incidentally it clocks higher on average. Power looks more like a GT PCB than and GTS.

It would be nice also if card would stay relatively silent.

(I have 12cm cooler on side of my computer case..right there were graphics card is.. huge help(I believe in many large coolers + very low rpm's)

That shouldn't be a problem in Vista, the prior problems with Quad SLi and Windows XP were caused by a 3 frame render ahead limit in that OS. This made the use of AFR, the preferred multicard rendering technique, impossible.
