frozen cascade

[kayl]

Very nice build! What did you use to make the insulation mold for the evaporator? What type of insulation?

i did a drawing and got duncan from XS to make them for me, thanxs mate

looks real nice can't wait to see how it all works out for u

thanxs mate, i also cant wait so i can use it to enter the gigabyte competition
beat me if you dare

Finished the flex lines tonight, brazed the cpu head and also one of the gpu heads. will braze the second head in a fortnight when i return from work

Looks good Kayl is that copper flex covered with steel braid?

stainless steel for the hole flex line
all lines pressure tested to 400psi no leaks

Whats your internal ID?

I am now a happy owner of a Cascade from Kayl.



On right cascade, left is SS. I know my picture sucks but its cause I don't have a tri pod for my camera, hence I move it 1mm and the shot is ruined. Also the batteries are low, which normally means bad pictures in this camera. The SS in on a cabinet so I can wheel it around

Of the flex line, i cant remember, big enough to fit 3/8" copper tube in the almost snug.

very nice fatguy1992, the first ever made cacsade You should be happy with that baby


little update on the cascade, almost finished both stages now, just need to braze in the 3 lines, cpu head and 2 gpus and its ready for some cold

[billdavis]

WOW i bet it weighs more than my wife!

[SAE]

lol^^
Depends on how slim she is

[kayl]

WOW i bet it weighs more than my wife!

well yes alot more than my wife, but not quiet as much as me


Managed to do the last part of the build, vacuum and charge the unit,
no load heads are around -103c and first stage -42c.
Still alot more work to do before the cascade is 100% finished, ill use it the way it is for now to get some load testing done. Then later do the electrical wiring correctly and install a gfroster controller to monitor the temps.

[kayl]

cascade is up and benching. Needs some tunning though not enough flow to the graphics card heads.
-98 for the cpu head and -40c for the gpu heads.
Not bad temps though for testing benching

[n00b 0f l337]

Wait do you mean -40C on ethylene?
That doesn't sound like you've got any flow that direction at all.

ya said it. i started off long, shortened tonight, 30cm off each line
i wanted max flow to the cpu head, not too worried how cold the gpus get.
lets see how it goes this time round

[kayl]

Not having much luck, this 3 head cascade is turning out to be a pain in the but.
After changing the lines and putting it all together again the cpu head couldn't hold load and was falling into the positive temps with heavy load
the gpu heads one on a graphics card and the other on the load tester were holding around -85c after a vantage 3dmark bench.
i pulled it apart to check the capillary line feed to fine that one was a little longer than the other 2, this would expalin why it couldnt hold load on the cpu head.
good point for other builders to note, as it will starve that line of refrigerant.
Second stage pressures are getting quiet high though with system all loaded, first stage isnt holding the load too well. THe condenser is too small and the case cant fit a bigger condenser
Looks like this cascade might have to be turned into a single head cascade

[eligray]

Do you mean the cascade above was your first or the first pc cascade ever?

What were your pressures with -85c gpu heads?

[n00b 0f l337]

No no eligray, this long thread is a showcase of Kayls cascade(S)

[kayl]

Thanxs noob

Cant remember now last time i picked up the blow torch, but it felt really good to do it again, especially first build back being a cascade.
Heres a start to my final cascade...

[SAE]

Looking good^^

[kayl]

Looking good^^

thanxs sae

unit together, just have to finish some insulation and final wiring and i can start to load test this babie

[Jort]

Very nice job there, nice to see old faces again building beauty's!!!

good luck !

thanxs Jort, phase change is very slow in aus these days to many second hand units of mine being traded haha
Nice to do a cascade as well for my first build in over a year

[Jort]

yeah idd and there are trading for such a low price!!

ah well its fun thing to do

Awsome Congratulations

[kayl]

the cascade i was building is on hold as havnt heard from the owner for a few months
New cascade bigest yet, 2x 2hp compressors :weirdo:

Looking good my down under friend.
Thanks for flipping the photo's over

no problems mate, this forum is where it all originated from
Unit up n running. Just need to finish the insulation and fine tune the unit under load.
Not bad almost did a cascade in a few days
