    -170 club on cascade

    sorry about openning a new thred, but i'm to mutch happy

    well, this is breaked on my 3rd stage cascade: http://www.xtremesystems.org/forums/...hlight=3stager

    i got some natural gaz out of my kitchen (95%methane):


    and after some tests i get my best temp ever on phase-change, probably on of the lower temp pics on xtremesystems



    1st stage is +- -60ºc
    2nd stage on +- -110 to -120 range
    3rd stage pressures was 220psi hi vacuum low. (i love this rotary)

    termometers and camera baterys dont help i need to be quick.

    problems: cascade very times stop and start... i assume this can be becouse the litle co2 natural gaz have. that can make ice on cpev for example.

    between tests i make this video of cascade breaking my last better temp (-144ºc) i'll make another of -170 break when i carge camera batery

    video: http://www.youtube.com/watch?v=KmesyD2xEOU disponible soon

    more pics and videos and test's soon, anyway i'll try to get r14 for 3rd stage, just becouse this is to bench and actual cpu's coldbugs somewere neear -130 -140ºc.

    I vote for drilling holes in ur desk, mounting the evap, and letting it ice the desk up a little. Just for show.

    I 2nd that, also letting it touch the side of your car and seeing how long it takes to ice up all over!

    This is one more reason why you are an Xtreme Legend

    You don't just push boundaries, you destroy them. Quite an achievement, and definitely the coldest temp I have ever seen on any casade cooler.

    Amazing, but completely crazy Propane is dangerous but Natural Gas...let's just say I hope no one else decides to try it.

    Amazing, love the resourcefulness of pulling the gas from the stove tap! I'm guessing your natural gas is primarily composed of methane? Read the wiki about it and it looks like an amazing hydrocarbon tail. Now time for you to start seperating the stuff and using propane on the first stage, ethane on the second stage, and methane on the third stage
    I want your HD 5970s and HD 5970 waterblocks.

    thanks ppl, i'm happy, maybe if i can get some pure metane i can try to bench some old no coldbug cpu's

    yes dimas you are right, the big thanks go to you, you told-me about natural gaz and methane

    on the youtube movie, it stops decreesing temps becouse dry ice or somthing on cpev. after some time it restart lowering the temp but i only have batery for 1 shot, not movie, i'll make another soon but it have to many stops to bench, thats why i need pure methane for try to load it. and to spend money i'll point to r14+argon to get some small pressures and -130 range to work on almost all conrroe the ideia of this cascade is benching hehe

    Maybe we could do a -170c+ donation! I'll stick in a £10 for a laugh but a feat of huge enginering.

    How much ya need?

    Super nice temperature there, congratulations

    I hope you'll not have the same problems I had with that gas: very cold no-load temps, and awful (I mean worse than with pure R1150 in third stage) as soon as you load it. This is due to the quite low molecular mass and specific vaporization heat of methane, so you'll need a massive flow to make it work.

    Good luck finetuning it, can't wait to see LN2 temps on a cascade
