-150C Supercooler build....

[Slickthellama]

You guys should use solder as a TIM, man, that would work so well if the core could take the temps for a split second. That would be second to nona as far as TIMs go.

2 words chilly.........expansion tanks!

Static charge!! @ 275 psi static. @180 psi Head operating with 10 psi suction. on both upper stages...

[captaincascade]

so it runs?

i thought it was still being built?

that must be a hell of a cap tube.

doesnt intel use solder under the IHS on some of the newest P4's?

[chilly1]

No captube and these are the values of the last three cascades I built, no capillary tubes fully adjustable loading and temperature control on the fly..

Actually I polish both the processor and block so that when you set the block on the processor and lift (with no grease) the block picks up the processor... so very little greas is needed.

[berkut]

about TIM's... im doing a small research on using cryo oil.... so far works very good, gonna test it @ -40C, right now it performs like ceramique

I think the IC7 is better when the mobo becomes the limiting factor, vcore regulator + mosfets seem more robust than Asus. Just a retail non-manufacturer modded board, my 3.2E grabs a 5101Mhz screenie at -100C, and a 4.94 Superpi run.

I have been saying that for 3 weeks now

[kayl]

the only thing that i have to study lately
is refrigeration.

but you got stable with which clock ???

see ya

[LardArse]

If you're talking about Prime95s and games, I do not run those, I don't think anyone with a cascade use them for gaming or folding and stuff.

[Reflex1]

its almost weekend ...how the -150C project progressing

[chilly1]

On hold, I am working on a cascade GPU.

[captaincascade]

anything colder than -120c is really a pain in the as, though im sure you will all want to learn that the hard way. Personaly i dont think its really worth the effort. i have gotten to -152c though it wasnt very stable. as you know, one of the reasons we use refrigeration systems as aposed to ln2, is the stability. i have down sized my operations. in an effort to build a stable, happy, and healthy -100to-115c system for our purposes. no more chasing rainbows. if its not stable, its almost not worth mentioning. though some may beg to differ.


she will be a happy little beast

[chilly1]

Well I am shooting for -178 with a controlled atmosphere chamber and a cold trap to keep it there. This is the half power point of CMOS, we should see signifacant increases in speed The current research indicates increases of 100% at these temperatures and that is switching speeds... Who Knows. Worth a shot... So you been there impart more wisdom please!

[captaincascade]

if your going to use a cold trap to reduce moisture, it is necasary that the cold trap be significantly colder than the area you wish to reduce condensation. maybe just hot air around your evap would do it. i thought about the cold trap idea, just seemed like a waste to have a colder cold trap than a cpu evap.

dont get me wrong, go for it! somebodys gotta!

[chilly1]

Actually don't you reach a point where there cannot be any more moisture in the air? i twill al condense at a certian point so if we hade a finite atmosphere and no permiation then we woulb condense all available moisture in teh cold trap. and if we had any leaks.... The reason this works is the TD between the atmosphere surrounding the board and the coldtraap..

[Gary Lloyd]

Why not just get rid of the air? Replace it with dry nitrogen.

[chilly1]

Exactly we use of the trap.. now we cool the nitrogen while insuring that no leakes in the system will cause problems. Simply if we hava air that is a sublimation temperature, this is where the moisture in the air goes directly into a solid state to a liquid state, where the moisture is condensing onto a surface at -100 and we insulate the evap head so that its exposed surface is above the dew point created by the cold trap, them no condensation will appear on the mobo.

[captaincascade]

ok well as long as you have it insulated and there isnt any surface area exposed that is colder than your cold trap. you will be ok.

why dont you just build the dam lyophilizer and get it over with. lol


chilly , are you familliar with the process of lyophilization? (freeze drying)same idea basicly as your doin, kinda,. only they use a vacuum pump. and they purge dry nitrogen over the product to aid in sublimation. that and the word coldtrap is replaced with the word condenser. I work on these suckers all the time. if anyone ever asks you to work on one... Run Like Hell!

I have like 5 gmp lyopholizers that are my baby's at amgen. no one else is alowed to touch these 1.5 million dollar machines.

lol, and they think i know what im doin... hahahah.

lol j/k

@ chilly1 : with what are u isolating ypur evaps ?

And after this experience I wouldn't recommend it to anyone, took a few weeks for the eyebrows to grow back.

blown up my first board with 8, but i forgot the reason
Actually im 14 and starting to build my first cascade after a long long offline time :/ I hope some off you remember me.

Maybe throw some dessicant in there for good measure?
