Liquid nitrogen, anyone?

Hi
where can i buy the ln2?

If you need to ask the question, you're probably not ready to use it!

BOC do it, but you'll need your own dewar to store it in.

In terms of money how much will cost this fuss.

twist3d0n3 · 31 Dec 2010 at 14:46

600 million dollars

I wish you all a happy new year, and please close my post,i should know google is "my friend"

Dewer.. 20l maybe a couple of hundred quid.. ln2 about £1.50 per ltr for small amounts (20ltrs) and to top this off youll need a decent pot (£120+) along with plenty of insulation materials and the chips to play with.

Hundreds of pounds for storage equipment, don't know how much the LN2 is but it isn't cheap either. If you want to try more exotic cooling methods dice is a good place to start.

You would also have to open an account with BOC as you have to rent the cylinders off them due to the need of them to be pressure tested every 5 - 10 years. Add to that the cost of a regulator and the appropriate pipework, CO2 might be a better idea and a lot easier and cheaper to get hold of.

Make sure you follow safety procedures with any sort of compressed liquids. Seriously!

Spend a good long while reading http://www.xtremesystems.org/forums/forumdisplay.php?f=156 before even considering doing anything!

W-why ? Seriously ? Liquid Nitrogen can do a lot more damage than it's worth.

Yeah, but thats part of the fun! Same for anything thats high risk.

Am I right in thinking you have to have the motherboard laying flat so the liquid doesnt pour out of the tube ? From the liquid nitrogen setups i've seen, the tube doesnt have anything on top.

I may try it as a small project some time thinking about it. A nice cheap LGA 775 Core2quad and some liquid nitrogen.

Most people that use Ln2/Dice do so for benching sessions for high clocks, so generally as they need to keep re-filling the Tube, the tube is left open ended.

So yes the mobo would have to be flat, as the Ln2/dice dos'nt last to long in the tube really, and needs constant refilling.

You can't run a computer permanently cooled with Ln2, it's used for short term benchmarking

Seriously, Liquid Nitro? You are crazy.

Frozennova · 31 Dec 2010 at 19:53

Starting with LN2 is a bad idead IMO, start with DICE to get a feel of pulling a pots temp down and getting past cold bugs and cold boot bugs. It will also be more forgiving as will do less damage to yourself if spilt on hands etc

Liquid Nitrogen

Hi All,
Sorry newish to all of this so please excuse me.
From a semiconductor physics point of view is the attempt here to get the junction temperature down to where you get into Hold Time territory, but not quite, bring up the clock frequency to ensure you get not quite into hold time or are you intending to ramp up then just use the coolant to act as 'thermal energy' transport ?

Best Regards
