belgiums first solid gpu tube's / blind 1.1
 

well after my first solid cpu container , that whase also the first one build in belgium .
here we go on to gpu pots .
first drawings !



still have to puts more meseurs on the drawings .
hope to start in 2 weeks , thats when i have the copper .
these puppy's will be build to hold 350watt heatload , a teatser at my school is gone make a model how its gone react to the heatload .
and evrything will be ajusted to max cooling !

now give me ure vision on the ppl :)

greetz blind

Well, I allready told you my vision of building a LN2 tube. looking at your tube I think you should get rid of the copper down the tube. It's just hanging there without adding any thermal performance. Another thing you should do is use maximum amount of steps. With this you would get a very small tube at the GPU hight and steps might want to reach halfway the whole tube.

hehe u think so ^^ , 1 ure design will fail to keep control off the temps and will use to mutch LN² .
also the load temps with controlled Ln² will suck so hard !
2 yes the slab off copper on the back will me removed , and steps around 2mm that makes 18 steps total .
now if u are sure ure design will do beter , just do it becaus im sure it will suck hard .
ln² containers are build to make the Ln² FLOW to where its needed and in this case the base , whet the steppers and maybe center pole this will be the only thing it needs .
been studie'ing other design's , exept kingpins . all have a flat butom !
there's wher im sure vince his gpu's have also a stepper design , becaus its the only way u can let the Ln² flow where its needed .

any other things u wanne know :p .

The temperature of LN2 will never succeed -196°C, though flow of warm N2 to the surface might indeed be boosted a bit by your design. It's good to hear more steps are used.

With my idea of creating a tube more contact area is created just above the GPU which will come in handy because you will create more contact surface just above the hottest part of your tube. My guess is that it reacts just like air would do to passive heatsinks, allthough I might be wrong. It's nothing more then a idea, I'm not feeling like actually building it, I was just sharing some idea's :)

well evrything has cold bug and this way u can controll temps as good as hell .

Doesn't the water buffer allow you to control the bug?

u really have te read more about Ln² !
water buffer no need with dragon evo ! but i have foud something beter .

water buffer???

keep on sleeping witte ;) , ones u start LN² il tell u my secerets :D .
water buffer is not know to most ppl but my cola trick is new and it works for me ^^

Teach me master

Does it keep the difference between idle and load even smaller?

I thought Hipro did an insane job keeping the delta at 5°C and lower :o

A water buffer is used to lower the delta between idle and load temps when using ln² :)

hhhmmm ask jort start bench @ -146°C when done -148°C or lower with the coca cola trick , whet the dragon evo the water buffer is not needed becaus the center pole is one off the best buffers .
witte when u start Ln² il teatch u , have a other studient ready for Ln² .
soon will strik with spi :) , we have new design for a solid copper cpu tube .
oyes the student is troman ^^

Hehe ... Steven really wants to get OPB, doesn't he? :D

Anyway, I wish both of you succes. What hardware are you going to use?

BTW: Isn't it normal that temps drop again at the end of the bench as the load decreases?

euhm NO! only when bench is done ,
when the bench start u want to get 1°C off the coldbug , when bench is running first sec add ln² till u are @ 10°C under coldbug .
this hass to be done fast and dont any more so when the bench is done ul have ure starting temps or little lower .
this is where the cola trick dos the work , it lets the ln² boil so fast the temps drop 5°C in 2sec's ;) .
so yes if been doing some test :p, lol at the meeting when we had this i whase like omg . becaus normal ln² ddos not boils *** fast and temps dont drop so good , goal on my quad is running 06 @ 4.9ghz :)

will have all sort's off hw , P35 will be a good chipset and if DDR3 gives that nice boost will go for it with a E6700 and my old X6800 , the guy i sold it to will lend it to me ;) .
u see i learned more about ln² and stuff :p , QX6700 benches easy @ 5ghz with 1.65vcore for pi 1m all 4 core's unable . oyes that whas on the brokken P5W64 ws pro so thinking that il hgit more with new mobo !

The first part is what I meant: when the bench has ended, the temps start to drop again. I never knew you had to add ln² directly after the bench start to really control the bug :)

dont think , u will find out when u bench Ln² :)

After multiple hours of benching you'll end up with a tube filled with Cola :D

For real now, what do you do with the Cola you just poored inside your tube? Does it float (it's iced after few seconds right?) on the LN2 surface untill you pick it out?

Ah wait, I think I finally managed to understand what you ment, it's not about the center pole, it's about the flat horizontal bottom of the tube itself you're talking about. It's no good, I agree, the approach MM uses to have more LN2 flow to the baseplate will certainly be better. Though, with your approach it's inpossible to get a center pole drilled out off a massive piece of copper, that's why I think a combo of both our drawings might be the best solution, though it's really hard for me to draw that in 3 dimensions :-p

cola = full of gas and stuff , this will flowed around the ln² and wil give it a boiling boost !

And besides the Cola trick, are there more things that we should have in mind when benching ln²?

good tubes and a stady hand , oyes like with dice first time do its with some one that did it befor :D

Because of the way to insulate or the way to use the ln² itself.

My second dice encounter (3000+) went fluently and i didn't really do a lot of insulation the first time (3800+ WR).

I guess the hardest part is to know when exactly you need the pour the ln².

with trying u learn :D

first solid tubes? are you sure of that? |D

:naughty:
