Ok , I heard that somewhere you can obtain the best in cooling . I refer to a Liquid Nitrogen based cooling system . Does such a system exist ? And how would I obtain one ? C'mon how cool (literally) would a nitrogen system be ?
wouldn't be hard to do one i've seen some b4 like da geeforce 4 and stuff but how much would it cost to kkeep it running is the problem it won't last very long and your gonna see urself out of pocket just refilling it with liquid nitrogen
ive seen the odd site with people nitro cooling chips, but only for experiment. i doubt even bill gates could maintain a nitro cooled system. (well, actualy, he proberly could). another thing is, where would u get large amounts of nitro? i was thinking though, would u need to push the nitro around still, or could it just be stationary in a waterblock? .icecube
You'd need to circulate it, albeit slowly. In fact you'd need to set up a two-phase circulation system like in your refrigerator, but more industrial-strength, with a compressor turning the warm nitro gasses into a cold liquid again. To explain the principle, over to the Physics Van Outrach Programme: "Basically liquid nitro is made by a machine compressing air from 15 to 3,000 pounds per square inch (psi). This is the same pressure used in SCUBA tanks. When you compress air, it heats up. You run that hot air through some coils of tubing; by blowing room temperature air over the coils, you cool the compressed air. Then you let that compressed air expand. It gets cold when it expands. You let that cold air blow over the coils of tubing to cool some more compressed air even colder. Eventually, the compressed air is so cold that when it can expand it doesn’t. It has become a liquid!" So there you have it. Liquid nitro turns into a gas again while cooling your CPU. You then recompress that gas into a liquid and circulate it again. Is simple, no?
So , although a good idea in principal , it is completly inpracticle . Pity . Any other idaes about how to get a below 0 chip temp ? Also , is it possible to get the whole case belowe 0 ?
it would be impossible to get the whole case below 0C. maybe you could seal the case airtight, and freeze the balls off it. but it just wouldnt work. there would be loads of condensation. you wouldnt really want to anyway. .icecube
C'mon ......... Super Conducting chips , hugely low system temp ....... You could run you chips sooooooooo fast
you theoretically could get a 0c case temp, but it would cost a damn fortune... as long as you seal your computer in an airtight chamber with 0% humidity, there can *not* be any condensation. where is the water going to form from if there isnt any to begin with?
are there any tests on how great an effect baking soda has on reducing condensation, by reducing humidity? Or what about stealing a bunch of those packets they put in shoe boxes? Just a couple random thoughts...
So I was driving home today, a hot summer afternoon having baked me to a dessicated crisp in the office, and I had my airco on afterburner. This got me thinking. My car interior is nice and cool. The air blasting from the vents as chilled as the Pink Panther havin' a Bud (true, true...), and it occurs to me: "there's no condensation in the car... It's perfectly dry and cool in here. Hmmm...". The issue is of course that condensation occurs only when an object is colder than the air that surrounds it. Humidity is drawn from the warm air as it freezes onto the cold surface; more warm air may defrost it again but the liquid remains on the surface (with Peltier cooling all this is an issue of course, as the waterblock/CPU are much cooler than the surrounding case air. Hence the condensation). With airco, cooling is a product of the cold air itself. The only condensation will be on the cooling grid of the airco, but the chilled air itself will be dry (even drier than it started out). So, if you use a really good heatsink, say a Swiftech MCX, and build a little airco that blasts its cold, dry air straight onto it, you should be able to get some, err... cool results, right? But if you chill the heatsink below surrounding air temperature you're stuck with condensation again. So all the air inside the computer case needs to cool down, and cool down a lot, to get overclockable results. The problem is of course that it is a very inefficient way of going about things; moreover, the outside of the case will do all the condensing now, so you need insulate the case to prevent that. OK, so imagine a big black box. It has double walls filled with insulation (hey, makes it quiet, too). In the top, or bottom, or wherever it has a small airco unit that circulates internal air in a closed loop, with heat exchanger outside the case. Thus the entire computer electronics are situated inside the inner chamber of that thing, bathing in constantly circulating, cold, dry, air. As everything inside, electronics as well as air, has roughly the same temperature, no condensation occurs. Voila, cool computer.
