Well, im new here and many peeps know so much more than I about OCing so I hope you can hang with me on this and help with info I need. I have seen this forum for a while now but relatively new to posting. I should start with my background. Im a master millrights "machinist" and programmer. I have worked in the manufacturing field for over a decade now and have led the industry in many ways. I was the one that created the MOP system thru manipulation of sensors for Okuma "which is standard on all there machines now". I only say this because people in the past I have brought up the idea too has generally considered me as some crazy loon with no grip on reality. I do tend to agree with them except 1 thing. I am 1 determined son-of-a-bish
I would like to start with just pasting my journal for you to read.
Starting of the LN2 systems.

Thank you for the continued interest. I believe that a closed loop LN2 system requires a very large buffer tank if you plan to use the liquid phase. This would take care of the 700:1 expansion that LN2 suffers when it is evaporated. Of course, there will be re-condensing to be done. Expansion like Freon is NOT possible in this model
Other option is to use LN2 is let it boil off. That is the cheapest way. Know that at these low temperatures you have to take heroic measures to keep the heat wicking back thru the connector pins and frosting up your motherboard.
The way most people do this is with a small cryocooler or Peltier junction. This can eliminate the LN2 and just stick a cold finger on the CPU. Hope this helps.

2 contacts. mainly both of them worthless. "Kelin" which is a provider of LN2 systems. and University of Houston "some jackass". Both of them have really nothing to offer.
Where I work has some engineers who found that Titanium would be the best product under such a harsh environment as 1.3 Kelvin.

Looks to be the only LN2 system in my price range. It also makes more LN2 per day than I would ever use. Blocks for the CPU will be made from Grey 28 Titanium. Have some at work I can have.

Liquid Nitrogen from the tap!
Liquid Nitrogen is now generated from the atmosphere and stored at your location.
Mini PSA series offers many different capacities in daily production rate of LN2.
LNS-1(Photo): CE Marked, Clean room compatible, 3 Liters per day production rate. Automatic filling.
NL-50 : Mid-size, 15 Liters per day production rate.
NL-300: Large-size, 28 Liter per day production rate, 100 Liter storage capacity.
Questions I have would be how long would LN2 last per volume on a highly OCed Proc. what's the burn off rate. I need to understand what flow rates I will need to estimate how much volume I would have to produce.
Why I want to do this. I look at the final stage. Before liquid the was air and the need for better and better airflow till we bought the Vantac tornado fans which are somewhere around a billion decibels "one of my cases actually took flight with these fans". then the liquid came in. Hell, every unit I saw in the beginning was about as trust worthy as my wife in the mall with a fat wad of cash.Then l8r models or the DIY models could have a $250 pumps " Iwaki MD30RLT". To make a long story not so long,then vapor etc. The final result will be LN2 "triple compressed for -210C.
If I create a dielectric chamber around the mb and it's systems then add some low pressure exhaust valves when running by boiling off the LN2 you would continually create the dielectric gases inside the system because of Nitrogen's 694 to 1 expansion. I think I will stop here just incase peeps think of me as some crazy loon with no grip on reality.:D
