Xtreme Edition LN Cooler by Otterauge

Hi guys,
Just got back from uni today and look what was here to greet me

(Click images for full res)




Otternase knows his stuff!
This think is a tank, bloody huge it is!

Mutant that is one nice looking pot there.
I bet that thing is heavy also, no need for mountings with that LOL

Cheers dude
Ottis work is incredible, it weighs like nothing else, 4.5Kg >.<
I lifted it and i instantly though i dont even need blots :P

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.

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

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.

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

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.

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...

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 !

That's what I'm talking about...

You need only little LN2 to control, other containers need more and then there is a risk to do to much...

Keeping temps in a narrow range is much easier with Andis containers...

Normally I have even less LN2 in the container compared to the pic showed...

Is it? I don't even pour LN2 during 1M with the F1EE. For 32M I pour every ~25 seconds. I consider a ~2 degree swing to be acceptable unless it is a bleeding edge run in which case I'll trickle pour and maintain a .1C to .3C swing. 3DV CPU test on the w3570 involves a trickle pour for the first 9-12 seconds of the test after which I let the pot boil off and warm up for the load screen.

Perhaps it also comes down to the CPU you are using. My chip flips its below -100C so I dance around -90C to -95C for the majority of benchmarks. I need to try one of these pots, maybe I'll borrow Brian Y's for a weekend

it's here whenever you want to take it out for a test drive



I have to say that I am extremely satisfied with my otti pot. Andy does real awesome work and the pot for me at least is heaven to bench with. Controlling temps is never an issue and this pot has been perfect for those insane suicide runs where temp control had to be perfect.

Keep up the solid work Andy

And findinf the right point is the tricky issue with the right amount...

I pour close to the switch of the test...

@Brian: but this one on the right doesn't look like the last rev...

good point.

I have contacted Andi about his new rev.
