Xtreme Edition LN Cooler by Otterauge

[Otternase]

Here is a genuine act of force of time has claimed. I wanted to build an LN cooler with a 150mm height, Ø74mm and a 4 Kg.
Large interior space without the ground to make a lot thicker.


The result is the 4kg and I think a well-designed interior space without a large capacity to lose.




sorry for my english

That looks incredibly pretty but it has a lot of wasted mass. Was talking to a thermodynamics professor and he figures anything more than ~1.5-2 inch(45-60mm) away from the heat source is wasted mass.

[Otternase]

I see things differently and there are 28 ~ 50mm

Right and F1EE has lot of wasted mass.
4kg bottom is not necessary.
3kg bottom is okei and with lot of exposure area it's perfect.
But if you have lots of copper why not.

Yes its easier to say a professor said it(and introduce immediate credibility) then how exactly your research into LN2 pots revealed these numbers, with out actually using one of Otternases fine pots to see for yourself how they perform.

That's theorie and not shure if structure is taking in account...

Rigt now I like the 3 kg to 4 kg stuff with this inner structure...

Agree here...

You can say, I'm a buddy from Andreas, but trust me, when I saw first time the last container I immediatly though, this could work great, and it excatly worked like this...

I benchend know two times F1 (2 different revs) and have to say, even with less wight it's more difficult to bench. You can't clock higher with the Otterauge-container, but easier to handle. The F1 is imho optimzed for a manufacturing process, when you poor in LN2, it's sparkles like hell...Enclosed a pic from last session, the LN2-level is more even in Andreas container.

When you bench, you need only little amount of LN2 to change temps, even in 3DV-CPU-test you can drop temps...I 3DV VGA-test only little LN2 needed because of mass...For me this container combines sensitivity AND stability better then I have seen before...

[Buckeye]

Thats very good to hear and I find the same results with the Phantom. Don't flood the pot as it makes the pot run warmer.

It looks like you are running about the same amount of LN2 as I do with the Phantom.

I agree also with the F1 comments, its a very nice pot also but has its limits. When I run max temps its very hard to get it to max temps and keep it there. It can boil over and get LN2 all over the mb pretty easy. It also seems to take more LN2 to bring down the temps then Phantom.

Sometime ago I also used a Micky Mouse pot which worked pretty much just as well as F1 in the temp range of the chips I was using, it had a little bit more swing to it but all in all its a good pot.

Controling Phantom is pretty easy to dial into a temp range and keep it there with little change. Just small splashes is all it takes at very cold temps.

Otternases pots look very good, interesting design that is wonderful to see as it breaks out of the mold to show things can work very well when stepping out of the mind set of some pot designs.

Nice work Otternase !

[Solarfall]

interesting design.. i've never seen such thing before how, does it perform, have you tested this yet ?

[ryba]

It's really nice work man!!

But if you are benching at -150*C and you will have crash/bsod/restart when yours CPU have CBB ~-100*C or more... have fun with it :P

[02wrxgt30r]

well I dont know much about LN2 cooling but I have machined quite a few things and it is a good looking block despite performance lol good luck

[msimax]

nice pot lets see some resuts on phII

let her rip

[ilkkahy]

Thats piece of machining art there


Here is bit offtopic but anyway...

I think containers have reached its peak as there have been several very nicely machined massive designs with lot of surface area. Couple of years ago there was debate whether solid containers can have internals at all

Im anxious to see the next step in the ln2/dryice cooling section with more advaced innovations considering ln2 feed and pressure control of the container/block (or perhaps controlling container temperature with additional dummy load). Man with ln2 thermos cup in his hand seems kinda "old" tech doesnt it?

There might be some business to it too for the one that offers first well thought and working setup which automatically controls the container temperature, lets say +/- 1K for the set up temp. Just little encouragement talk for someone who thinks that could do it

[sofos1990]

Wow that's a real monster.....
Nice work buddy

[WhiteFireDragon]

what's that glowing blue light? if they were LED's for bling, that would be totally useless for benching.

[Otternase]

no is just the structure better to see it as a honeycomb structure with a connectionless

Interesting design, let us know how it performs.

Did he forget about thermal conduction? Mass is there to stabilize a container, balance that with good pull-down properties and you have a winner.

I don't think he made that mistake.

I used it. Idle -190.00 Load -189.8 It was the Lightest Pot I have ever used to date, less mass than my cheap home made DI pot.......

On topic

That is a very interesting concept and sweet looking pot, I dare say that thing will not budge a degree loaded......Not to mention who needs mounting hardware. Looks like you could place it on CPU and rip.....

[Otternase]

Thank´s all guys,

I think there must be a total approach. not only the ground is responsible for everything. The grooves in my other coolers bring a faster and faster transition response

This has a really large interior area with a concentration towards the center.

Cones in the middle, in my opinion, too slow and tend to be more often in the cold bug lands.

These are my thoughts


thank's for google translate

Lots surface area close to the heatsource is all you need. Having heavily machined copper 4 inches from the heatsource isn't useful. We only have these thick bases because we can't quickly remove the heat being generated due to insufficient surface area for the respective heatload. Take a look at direct-die evaporators that are very successful. Gosmeyer's latest evap, a twist on eleven's design would work quite well in a forced LN2 application. Think it needs to be a little wider but it'd kick ass Anywho, I'm going off topic but I'm going to try and get a mass evap fabbed up and see what it'll do on LN2.

[crustytheclown]

Man your work is a piece of art to say the least.You've made it a science and you 're definately THE PROFESSOR!!!

[BAGR_001]

Oh man! That looks realy good. Especialy design :-) But weight is horrible :-(

[mpc]

Looks very nice

You better haven't got a CB on your CPU. If you hit it, you will porbably have to wait for 24h until you can bench again

[tcorbyn]

GREAT LOOKING POT!

[Otternase]

Thank´s,

Cu for new Coollers is coming

[Otternase]

And so then he finds his way into new home
