Liquid Nitrogen???

I am trying to make a super cooling system, using a compressor, a radiator and a Niobium block for the purpose of the heatsink.

But cant decide in wich Gas or Liquid to use:
-Liquid Nitrogen
-Liquid Carbon Dioxide
-or Amonium

If u are familiarize with these system or componets, I will be glad to recieve your help.

Current system that I'm trying to build is:
-AMD Athlon 900Mhz, 100Mhz FSB
-Soyo Dragon Plus
-and the rest is irrelevant.

With all that and the appropiate cooling, I think I can overclock it to 3.724 Ghz if the Proc structure and the Mobo can handle it.

If u have any ideas i could use please e-mail me
valak@phreaker.net

Thanks...

This is what i call MEAN STUFF!!

It can get CPU temps down to -100 oC

Where you getting the Nitro ?

How much est. will it cost you ?

The nitrogen can get your cpu to under -176 C

I can get it from my scholl or create it by destilation. The nitrogen has a lower fusion point thant the oxigen

Or through the atmosfere, make oxigen go through very hot iron and the nitro ions will stick to the metal, etc. many ways to get it.

But only with the Niobium metal, and a symple fan u can cool it much more than cooper will.

But the important thing is, how to deal with the condensation and other things too.

I would think that an ammonium gas leak could be very bad for you... So I ruled that one out. If you really are going for the ultimate, Isn't LN2 about the coldest stuff you can find?

As far as the rest of your system reaching those speeds, I would also think your gonna have to cool the MoBo as well. Might want to consider a total imersion(sp?) cooling system. I've seen it done with dry ice and mineral oil, but that was a 'disposable' cooling system...

[Anon OC'er]

For condensation, the total emersion solves that issue as nothing is allowed to come into contact with the air hence, no condensation. Otherwise your looking at using lots of silicone and neoprene. Check out this link -

Mostly unrelated, but the insulation ideas are the same.

So what's this Niobium stuff? Some sort of unobtanium?

the Niobium is a gray lustrous metal that is commonly used in alloys "Tantalium, Vanadium, Titanium.

The good thing about it is that it is a super conductor, it has more thermal conductivity that cooper and aluminium thogether (0.125 cal/cm2/C).

The bad thing is that pure niobium is hard to find u can get it but on alloys, but if u can get a block of pure or almost pure niobium, just take it to a place where they cut alluminium (niobium is as soft as gold), just make the diagram of the heatsink u whant to create in autocad depending on the processor u what to use, for AMD, heat disipates to above and for pentium processors heat goes to the sides. With that they just simpliy put the diagram on the computer and they have those robotics arms controlled by the computer, that will the heatsink just like u designed it.

Or u just can simply download the diagrams.

Dont worry about the price, the niobium can be found almost in the whole planet, and if your desing is good, u can show them to computer bussines poeples and sell it to them.
;-) Good money on it...

With all that and the appropiate cooling, I think I can overclock it to 3.724 Ghz if the Proc structure and the Mobo can handle it.

not to be rude or anything but that cannot happen...the Pentium 4 is .13micron process and someone using almost the same cooling plan your using only got it to like 3.6ghz...

your AMD is only .18micron, and 3.7ghz is way beyond the limitations of that CPU...also u would need alot of Voltage to be running through that CPU, which most AMD motherboard even with voltage mods cannot handle.

if u really want to make it to 3.7ghz then u should get a CPU that using .13micron process (a P4 which is already out or an AMD Thorobred which is comming out in 3 months)

[Syk0tiK]

and besides all the other facts, i dont think they make a motherboard that is capable of over 2.6ghz for AMD systems...

200fsb x 13 is only 2600, most motherboard cannot go above 200fsb or 13 multiplier. (in fact i dont think they make a motherboard that can go above 200fsb)

also you would need to have EXTREMELY good ram in order to get 200mhz FSB even if you found a motherboard that can go that high.

[Syk0tiK]

i did some math, and if u did have a Motherboard that cound handle 200fsb, you would need a MC value of above 18.5...which they dont make motherboards that go that high

and your Soyo Dragon plus can only goto 200fsb and 14mc, so the highest OC u could achive with that mobo is 2.8ghz...which is still too high for .18 micron process.

the highest Athlon ive seen is 2.1ghz with a VapoChilled AXP 1800+ AOGOA, his name is JCViggen at hardforums.com if u want to go there and get some helpfull information.

look for the SY-K7VDRAGON+

-FSB: 200/266MHz

-It uses DDR memory That runs at 266Mhz

-About the Vcore voltage, that could be a problem, but I have to cool the Mobo too, so a good voltage mod could be used
-About the proc structure that is a problem I expected, but still need more reserch on it.

But thanks for the suggestions I appreciated it...

Can you please remove that image you have in your signiture.

Thanx.

First of all, your MoBo that supports 200/266 is the DDR rating. The FSB is actually at 100/133.

Secondly, the KR7A goes to 250FSB (500DDR), and I think the Epox goes to 233 (466DDR)

250x13 = 3250

In order to reach these speeds, almost everything in your PC will have to be cooled including the trace...

And finally, the VCore is limited by a current sensor. You can mod a board to give more volts but once it reaches a certain current, it's gonna stop. But that doesn't mean you can't mod the current sensor...

[Jason]

Actually, they used to (and still do) make A/C systems that use amonina... That would probably be the cheapest route since you can get off the shelf parts (the compressor, evaporator coil, etc..)

I don't know what all is needed or if it is even possible to recycle LN2 or LCO2.

[Syk0tiK]

like i said, even if u get a mobo that can do 200mhz or more, you are gonna have a REALLY hard time getting it that high because there are alot of limiting factors.

[Anon OC'er]

I don't think it's all that unreasonable. People get 170-200 FSB without anything near as hardcore as what this guy's talking about. I would think If he can get his voltages high enough, and his temps low enough, He should do fine. Will he hit 3.7GHz? Probably not, but it's a nice goal!

Good luck! And I want Pics!

Anon, reallly, the KR7A goes to 250? because i have that board, and in the BIOS, the limit is 200
