So Me and My Brother are going to design a LN system....

[mep916]

Yes that is the norm.... but what if???? I have access to the largest Engineering firm in the southern Hemisphere (or so Ive been told) with heaps of smart are hell engineers lol (my brother included) and basically any material possible.... So we are investigating to see if it might be possible.

Well I know Yeti's smart with this stuff. All I know about LN2 is what I've read at xtremesystems and that's very little. You should talk to some chemical engineers about this I suppose. It's a great idea and it would be awesome if you could somehow come up with a 24/7 system, although I'm not sure how long a chip could handle those sub-zero temps. A LCS or TEC system would be more than adequate I think. Good project though.

although I'm not sure how long a chip could handle those sub-zero temps.

Yeah I just read that chips die due to the massive temperature changes so wouldnt be a good long term thing, unless you could cool/warm up the chip slowly?

Maybe use LN2 to highly cool heat pipes that go to your CPU block???

My brother said he was going to start a basic design on the weekend, they have chemical engineers there Im assuming cause they make some pretty random bizarre things.

But would it just be awesome if you could run your chips at something like 6.5ghz stable lol.

We were also thinking about a dry ice system.... Since I found out about the massive change in temp thing... Whats a substance that could basically keep the chip at zero no matter what? Something thats say -20 or so.

Phase change style system, using a compressor from a window ac or whatnot. 6.5Ghz is kinda overkill idea, as the voltages required for that would kill the chip pretty fast...

 

[just a noob]

yeah, it really isn't the temperature that kills the chip, its the amount of voltage required to reach those clocks

That's nice that you have access to all that equipment, but you need the knowledge and experience with refrigeration systems in order to do this kind of thing. Chemical or mechanical engineers might be of help, but you should really have a cryogenics or refrigeration engineer.

Thermal shock would probably be easier to deal with than building the cooler.

You would freeze the heat pipes unless it was specifically designed to work at low temperature (i.e. low temperature working fluid). Really, if you're going to build a cooler you might as well directly attach it to the CPU. The reason people use LN2 is that it can be produced in a liquefaction plant and transported anywhere.

If you do get a design worked out you might want to run that by me before you build it.

Dry ice is about the same as LN2 as far as being a consumable and what hardware is required. As far as systems what you could use to cool the computer besides LN2 or dry ice - the easiest would be a liquid cooled TEC. After that you would get into basic vapor compression cycle refrigeration, then multi-stage vapor compression, then probably an autocascade system, then more exotic cycles (Stirling, reverse Brayton, Claude, Linde-Hampson, Joule-Thomson, etc).

Hahaha liquid nitrogen.....yeah because you can just buy that with no permits at like the hardware store....

If you want to be innovative and actually perhaps change computing or over clocking you need a cheap, widely available and efficient way of cooling a computer.

actually you can, most welding shops will fill your dewar if you're over 18, air gas will rent you the dewar+liquid nitrogen as long as your 18 as well i think

Yeah he can.... I can even get uranium if that would be of use...

He was going to work on a cpu block... Nothing fancy yet as we still dont know lol. A CPU block that would fit onto AM2/AM2+/AM3 sockets. Would making it out of sliver be of any real advantage? I know silver is the best thermal conductor (isnt it??).

the easiest would be a liquid cooled TEC

Whats that?

 

[just a noob]

actually i think gold is a better conductor that silver, as for a TEC see here, its mainly an electricly powered heat pump that has a hot side, and a cold side, i think the biggest one that i have seen was a 437 watt tec(at 24 volts) most tecs require a dedicated power supply(meanwell is the one you'll see used most commonly) most also require a special waterblock(a stinger varient, or an artic spider) as the tec is about 72x72mm, and it needs to be wedged in between a "cold plate"(a copper peice on the cold side that fits the cpu, and allows you to apply much more pressure to the tec) and the actual water block

 

[ScottALot]

And wouldn't compressing the LN2 require something to cool it? Really the only thing I can think of is some cold source in front of the front fan.

Liquid nitrogen is quite easy to come by....

Even then, you only get like half the wattage of the TEC worth of cooling, your better off running a vapochill sorta thing. Silver is a better conductor than gold FYI, and diamond is a better conductor than silver.

 

[ScottALot]

Why would you need a permit? It's not like it can blow up or anything *sarcastically*

 

[just a noob]

actually, if you are looking for ln2 temps 24/7, you could look at building a five stage unit(on full load it is 83 db's, and consumes around 1 euro's worth of electricity in an hour)

 

[ScottALot]

But I don't understand the point of huge overclocks if you aren't going to use the capabilities to actually game or something.

 

[lovely?]

Whats that?

electro-plate nickel onto it. im not sure about ln2, but silver tarnishes nicely.

 

[ScottALot]

Gold conducts electricity very nicely, but mercury will tarnish it.
