To get rid of condensation at such low temps why not use a freezer, not only, it takes care of the mobo and gfx but 2 cascades/machs/vapochills could fit inside and would lower the temps even more. If i'd ever get to do this, this is what i'd do.

Just imagine... a super 3-Stage Cascade in the ultimate benching environment. THE MOON, seriously let's get together and bench on the moon :rolleyes: no humidity, good ambient temps, nice scenery kinda like Texas... :rolleyes: Although the big thick moon gloves might get in the way of mousing...
Napalm, the feezers much too small... it'd be warmed to ambient temps in 5 minutes. Now the second best place to bench (after the MOON I guess) :rolleyes: would be a walk-in freezer like at some restaurants! Fun. I just think we're a ways off from having a commercially viable -100C Cascade anytime soon. REMEMBER I have a completely functional -140C cooler right here next to my desk that i'm not using 'cuz I don't want to spend $1K on frig'. If I really wanted to play around with those kind of temps, wouldn't it be logical to play with LN2?? :rolleyes:
Plus!! I want to freeze tennis balls and throw them at stuff, I want to make LN2 ice cream, I want to freeze ping pong balls and throw them at the squirelrs in my back yard. I want to put a surgical glove on my hand with hot dogs shoved into the fingers and MY fingers in the palm. Then I'll dunk what appears to be my fingers (hot dogs) into the LN2 and then take a hammer then shatter them in front of wife/kid. I want to freeze a couple cans of shaving cream, peel open the frozen cans and toss the frozen shaving cream blocks into the neighbors Corvette convertible who wakes me up Saturday morning mowing his lawn at 7AM. Can anyone imagine what happens when the block of shaving cream returns to ambient temp inside the car interior?? Hehe
Ahhh....LN2, can you possibly have so much fun with a Cascade?
C
LN2 is cheating... one time use. you cant re-use your LN2 like u can a cascade.
I use to think that way... but hell, Cascade is just as Xtreme as LN2....the only thing unfair about it is that it's too damn cold! hehe...

Colder than Ln2... Will do 14K
This is setting on my kitchen counter.... it's a cryopump 2 stage displacer uses hydrogen.
:slobber:
MUCHO fun...
C
Fugger has the hydrogen compressor and all we have left to do is hook this baybe up... It Should do -180C @ 200W if I can the first stage displace to run at 100%.
Will be very interesting to watch...
C
I need to build a vacume chamber and we will need to condense all the oxygen and nitrogen from the space for insulation.......will be 3 days between runs..... unless we can do it all remotly....
wow...
is there anything colder than LN2/that hydrogen compressor dealie-bob.. lol?
i think ill have to win the lottery and drop 15k on some -300c cooling and submerge my comp in mineral oil or something LOL. if i get the $.. im goin for it.
what kinda temps should that hydrogen thing give fugger when its in a cascade or however it will be used?
I still like the dark side of the moon idea :rolleyes:
C
isnt ambient dark side moon temps somewhere in the three digit negatives?
suggest it to Tom Holck :pQuote:

Well I will try it in a month or so but it will do only 70W@40K and if I am guessing correctly it will be around 200+W @ 150k -123C Really insulation will be a #@@$%@^.
This uses a 5 hp hydrogen scroll that removes the heat generated by the two stage displacer in the cold head in the pic. A displacer has a heat absorbing disk that will modulate at about 5khz in the head to transferr the heat from the cooling surface to the rejection surface this in turn s cooled by the hydrogen gas.
I think it's called the jenken cycle. Simmilar in function to a stirling displacer...
Yes we willhave to decal this with the proper attire when we runit.;)
I hope we don't leave a crater u know dark side of the moon and all...........
so that unit shoudl provide about -123°C when its put together?
amazing. how cold theoretically can these kind of systems get? before you must use something along the lines of LN2?
LOL!!!Quote:

Ahhh....LN2, can you possibly have so much fun with a Cascade?

Earth's moon ? Nah, how about Neptune's moon, Triton, –390°F ? I think it's the coldest place in our solar system, it's got active volcanos that look like geysers and shoot crystals of nitrogen, perfect place for cooling.
Really this is a cryo pump used to cool superconducting magnets in an mri imaging system. Nitrogen can't get as cold as this thing.
It will go to -259C or -434F
-434F ??? Holy crapn' shnitz !Quote:

chilly1, so how much for a fully operational kit, the whole thing ? When ?
It will only cool a 1Watt load at those temps. -123C @ 200Watts though. I think Fugger has maybe $300 in it Ebay or something> Bought in pieces and now almost ready to go.
Actually a functional unit rebuilt is 5 to 40 grand depends on how many hours on it.
Sometime after Feb 1 need to do ces (consumer electronics show) first....
Wanta make som nitrogen snow balls???
What's the generic name for this sort of cooling chilly1 ?
How does the hydrogen arrive ? Do you or Fugger smoke ? I can't imagine not smoking my pipe whilst benching ( j/k).
I guess this would be the most extreme cooling ever applied to a PC cpu ( technology wise, rather than temp wise). At what sort of temps do semiconductors start to lose their semiconductive properties, if at all ? If V=IR you wouldn't want R to go down and I to shoot up in nomal metals as well.
To avoid consensation it might be quite nice to have the entire motherboard in a perspex container and blow Nitrogen through it. If you let the Nitrogen expand it would also be cold as well, so killing two birds with one stone.
The whole motherboard in a sub zero celcius , zero moisture environment with extreme cooling applied to cpu and gpu would produce excellent results.
Just theorising of course. Might be things I have missed ( more than likely ).

1 watt load ? What about 0 watt ? Just $300 in parts, wow ? Of course it's the know how, work, time that costs. So, if i'll ever have the money for a functional unit like this, you're the One to cantact ?Quote:

This is a cryo pump and is used in vacume chambers, this is a tame one there are cryo pumps that can go down to 2K ...-456.07
The other end of this is a five hp water cooled hydrogen compressor, It uses absorbers in the discharge to get the proper density of hydrogen. This cryo pump will freeze nitrogen.
IBM has had CPU's at -200 and lower, they discovered that CMOS's switching speed is doubled at these temperatures.. what we are finding from the Ln2 guys is that around -120 something is happening that wipes out the processors. It may be that the dissimilar elements of the processor are contracting at different rates and this is the breaking point???
This was a lucky find on ebay from salvage... just luck. Fully functional units are VERY expensive. We may just get it working and sell it. But it would be nice to try it.
:eek: :slobber: :sick:Quote:

What i mean is.......that's just sick.
