Polycold/Chilly1 Modded Autocascade Rev2

[s7e9h3n]

Still some more testing to go, but here's the preliminary result of Chilly's second go around with my 6-stage Polycold autocascade:

14 gasses and temps still falling.........more to come ;)

[aussie_guy00000]

6 stage auto:eek: :eek: . Haven't heard of this one b4. I'll shall now go and seek out any previous posts on this :D

Edit: Can't find any, although i didn't look real hard, meh.

[hawaiiparty]

are there previous post on this autocascade with photos about the realisation?

[jinu117]

LOoong time ago. I hope capacity holds up :)

[hawaiiparty]

anyone could give me a link...excuse me for my english..

[s7e9h3n]

ATM, I'm struggling with the mount. In addition, there's a section of the suction line that still needs to be insulated before temps stabilize:

Chilly says the unit can be tuned for -100C temps as only 5 of the 6 stages are running with one more left to go ;)

[s7e9h3n]

Not so bad :p:

Nice s7e9h3n. Now you need to get a chip that has no cold bug. Maybe a 670 would fit the bill. An 840xe would also be pretty good.

[Sneil]

how do the evap load temps hold with that auto?

[Cpt Twitchy]

Very nice unit. Hope she holds the load well for ya.

Couple questions:

How can only certain stages be used? can some be turned on/off?
Can someone please show a diagram of how multi stage autocascades work?

Thanks

I really want to see the insides of that thing and how you don't need all the stages to run :D

[aussie_guy00000]

I thought about planning a 3 stage auto cascade. I guess you'd just have to plan it out well and choose the right gases, control the condensing temp of each stage and charge accordingly. That may sound like i think it's easy, but I know it isn't :D

[Waus-mod]

Man... thats one heavy autocascade! nice job stephen

not sure what load temps were not posted that i could see.

-46c is nice that would make block temps around -60c hey s7e9h3n at load??

AFAIK, this cpu has a bug @ 300HTT and ~-42C. Other than 300+, I haven't seen any signs of cold bugging even @ 13x269 @ ~-47C.

[s7e9h3n]

how do the evap load temps hold with that auto?
Before this second round mods, the unit was able to hold @ ~-20C 1.6V loaded. After the first regas (with 5 stages functioning) load was @ ~-26C 1.6. Chilly's added more ethelyne since then and now all 6 stages should be going and I'd expect temps ~ -30C loaded @ 1.6Vcore

The stages can't be turned off/on. When a stage isn't being utilized, I think it just means that the gasses aren't helping condense one another by the time it reaches that particular HX. I'll get chilly over here to explain specifics...

This is the same unit ;) But this time, he's got a few other gases in it including r116. Haven't really load tested too much with this new blend, but preliminary results have the evap @ ~-68C loaded (haven't checked core temps) and ~-44C Idle @ 1.65-1.68 Vcore

AHH makes sense now, thanks.

[s7e9h3n]

AHH makes sense now, thanks.
Tim
I talked to Chilly about that and I may be wrong. He doesn't really know EXACTLY what's happening in those HX's but his guess is that when the unit's charged with more low pressure gasses than high, the LP gas will fill more than one HX and thereby making the HX useless. Definately doesn't do that now (note the FSB) ;)

Tom Holck's beast is a dual-compressor cascade (although it does perform outrageously for only two compressors). Mine's a SINGLE 1 horsepower, 6 heat-exchanger, space-eating moster :p:

I seem to have run into another slight prob that I haven't experienced before......

Chilly, will you give us more details? compressor? gasses?

[afireinside]

Gettin chilly there huh ;) Looks like my x800pro:

http://afireinside.evilspork.net/AFI/OPTERON/frost1.JPG

I never had a frost over issue on my dfi nf4, even with less insulation. When I'd let it sit at -73c tube for 20 minutes while screwing with GPU tube I'd frost a bit on the heatsink but that's it. Are you running IHS on? That may be why... Transfers cold a lot more. As soon as I took the shim off my x800pro all the frosting issues went away.

Yup the IHS is still on. Another oddity I've noticed with this auto are the evap temps. The other day, I was running superpi 8m and before the test started, my evap was @ -72C idle. The fully loaded temps only crept up to -68C......a 4C degree delta :confused:BTW - this was @ 1.65Vcore.......

[s7e9h3n]

Chilly, will you give us more details? compressor? gasses?
The gasses part I would need chilly to answer, but in terms of compressor - this unit's powered by a single 1hp tecumseh 220v r12 compressor........

[Gray Mole]

Sounds like whatever Reg did this time worked :D

I thought your Auto was pretty good before but now i'ts just amazing. I don't know if I've ever seen frost like that from an Autocascade, or if I ever will again.

You must be very proud, mate :toast:

All credit goes to Chilly1.....ATM, I'm running 32m @ 1.71Vcore and -64C Evap LOADED.....:cool:

AWESOME Steven - Man I have to see this baby one of these days in person!!!

[esdee]

i see it has temps similar to dry ice.thats nice ;)

the question is, (except the display of skills and knowledge) does it worth to make such a complex system, or simply add another compressor make a classic 2stager ?

many :toast: to chilly for this unit

[jinu117]

Worth the size and money and time spent? NO. Worth investigating, yes. After all, this unit is good way to figure out how really autocascade should be done and once we get firm ground like we have done on single stage and cascade, could become viable option for autocascade. Not everyone want cascade, but might not be 100% happy with single stage either. For someone like me who wants cold temp but want to keep things quiet and reasonable, even 10c improvement by going autocascade might be viable option. This could be the future of high end vapo phase change cooling using single compressor :)

There's not that many people out there who could actually build a unit such as this. Even Chilly1 admits he doesn't have a firm grasp of what's going on inside the HX's of this unit. He keeps on telling me that one day, he'll strip all the foam insulation off my unit to get an idea of how this thing is built. Another thing about this autocascade which makes it unique is the fact that it was built for 24/7 use. I would keep the unit on continuously if I could prevent my mobo from frosting over and if I didn't have to dry my clothes in the dryer (this unit plugs into the 220V of an electric dryer)......

[MeltedDuron]

dry your clothes on the condenser :p: seriously tho, that is one sick puppy!

Awesome looking unit and results there. What week chip is that and whats the highest vcore you've attempted on?

Thanks
Tim

EDITED for hideous spelling

[s7e9h3n]

Awesome looking there. What Ship is taht week etc and wahts the highest vcore youve attempted?

Thanks
Tim
Hmmm....I'm gonna attempt to decipher your question and take it as : "What week is that chip, etc. and what's the highest vcore you've attempted?" lol.....

Well, the cpu's a 0512MPMW and it's showing no signs of the cold-bug. The highest vcore I could enter windows was 1.74V - before the re-mods. I've been able to enter windows @ higher vcores after the mods and surprisingly, the temps barely budge. ATM, this unit's capacity is unbelievable. Temps are basically the same @ 1.65 - 1.73Vcore with a delta of ~4-6C between idle and load on the evap.....

[Cpt Twitchy]

Woah that was some horrible spelling, sorry. You should work for the CIA with those decisphering skills.

OK now you're just showing off :p:

Seriously though, I can't believe how well that thing's performing.

I barely scratched -60 under load on mine, with a 2hp compressor, and that wasn't even as much load as you're pushing on this thing.

Myabe someday I'll go live under Reggie's stairs and be his biatch for a while and see what I could learn from the man :D

[chilly1]

yes very expensive gasses, and there is some serious wierdness going on herer this autocascade sounds like a compressor inthe foam and also has a sound like a river in the head..
It may use teh R401 and the other low pressure gasses to act as a liquid cooled block... and do all the work in the foam??
THe captube to the head is larger than the ones looping back in..

Spray the board in laquor or cover the socket area with nail polish and frost is no problem ;) Or just pop the IHS and never worry about frosting again.

did that they gave it a part number and it has its own UL listing so no go on the gas blend from polycold..

[bh2k]

Didn't you mention the origional gasses inside the autocascade were highly flammable?

[wdrzal]

by law their should be a
"material safety data sheet" available for the unit. I,m betting they don't have the percentages reveiled but the base chemicals and gases should be listed. that may tell us something about the types of gases used.

What model is that polycold?????

I'll chip in to buy some "replacement" foam. LOL

there is a good chance this was developed at some university, anyone know where??????
