Liquid CO2

yes, its possible to cool with liquid co2, so what?
nobody does it, cause it doesnt make sense...
and you certainly cant cool 7 cards sitting right next to each other in a case with liquid co2... to run folding@home... thats just beyond ridiculous!

fermi was there. they demoed an nbody simulation on it. they even said the silicon was a few days old. i am guessing you didnt watch it.

right, they fly press from all over the world to show them their new gpu... and then dont show it...

but the DO have it! i saw an ihs with its code name written on it!
and i saw some flashy animations on a big screen that were run on it...

just like rumsfeld had proof of saddams weapons of mass destruction...
i saw tons of satellite pictures and documents and videos! :P

im not saying nvidia didnt have working gt300 at gtc... what im saying is, there is no proof... it would have been possible to do the entire show they did without even having finished the gt300 design concepts and having no silicon whatsoever... as such, the entire event was a failure and waste of money imo... they didnt show a gt300 wafer, they didnt show a gt300 chip, they didnt show a real gt300 card, they didnt show a real gt300 card in action...

back on topic, and back to reality...
3-4 weeks until gt300 is supposed to be available in retail...
still no signs of it, nothing...
none of the usual suspects is even hinting that he already received a sample or hinting at the performance...

shops usually get cards just days before the launch, sometimes a week or two... distributors usually have cards 1-2 weeks before launch, card makers have them 2-3 weeks before launch... so evga, xfx, asus, gigabyte etc "should" all receive their gt300 cards this week or next... lets see

I have good experience with triple SLI 8800GTX overclocked and quad SLI on air. Even though I have no experience with more cards, I find it very difficult to believe CO2 is not enough. Liquid CO2 is very cheap. I believe it makes sense to refill a liquid CO2 tank every five days when we need to run 7 overclocked cards 24/7. We are not talking about extreme overclocking 7 cards for 24/7 folding here.

While it is not *impossible* to do, consider:
1. The amount of heat output generated by 7 overclocked cards + CPU is quite high. This will result in a very high burnoff rate for the liquid CO2. Whether a single tank is enough for 5 days (5 days!) is debatable since it all comes down to compression and cylinder size, but it would be a fair amount of CO2 required, which brings us to;
2. Unlike the air you have used to cool your cards, the exhaust from his rig is able to render a man unconscious in a number of seconds and kill him in just a bit longer. There are ways of dealing with this as well via ducting to outdoors, but this just adds in to how elaborate the setup has to be. Again, not impossible... but given he made a single post claim on a random Internet forum, let's not give him too much credit, shall we?

maybe the guy was high off CO2?
