Goliath Triple Cooling System

[Zucker2k]

You better hook that thing to an x48 board and a QX9770. Anything less than that...

[Sweeper]

I finished milling the CrossFlow water blocks and thought I would share a few pics.

[Zucker2k]

I gotta say this... to see you spend this much time, effort, and money to build this amazing cooling system reminds me why I need to build my next rig around a 'cooler' rather than the other way around.

Really nice, we are waiting to see finished product.

Man you keep topping yourself...I have to wonder :what next???

[moditir]

my eyes have honestly never seen anything even close to that in beauty.

GREAT WORK YOUR MY HERO

[karbonkid]

I just stumbled across this thread and i have to say... :o beautiful!

[jinu117]

I just want to see it working well unlike one major cascade endeavour that never worked (it looked beatiful too). Be persistant

[Sweeper]

Thanks guys for the encouragement....I will finish this thing with a little luck. The major problem I see is wiring the controller to cycle the compressors. Does anyone have experience with wiring multi zone controllers? I have a Minco CT124 8-Channel Temperature Monitor and manual, but I'm not that good with wiring HVAC controls.

Any help would be greatly appreciated!

Excellent build sweeper, your fabrication skills are amazing. Just one observation, your insulated chamber, you don't seem to have a thermal break between the inner and outer shell where they are joined together (where the lid will seal on the box). This will allow heat to travel through the metal/alloy and into the inner chamber. Whilst this probably won't have much effect on your temps, it will result in condensation forming around the lid seal. All coldrooms and freezers have a plastic section where the inner skin meets the outer skin to prevent this, commercial freezers even have a heater cable in this plastic section to help prevent condensation better, and they only run at -10 to -25c, you're planning on running -40. I think you also might run into trouble with your polycarbonate lid, I think it will allow too much heat into your inner chamber, and I think you'll have a lot of difficulty reaching the desired temp. By comparison armaflex insulation has a thermal conductivity of 0.036-0.04 W/m.k, whilst polycarbonate is around 0.19-0.22 W/m.k (around 6 times higher). If you use a bigger compressor to achieve the temp, you may then have problems with condensation forming on the outside.
Also, how do you plan on regulating the water pressure to 150psi???
Anyway, best of luck with the build, you've got a seriously hardcaore set up there

Thanks for your observation....you have a point about the inner and outer metals joining at the corners. The inner and outer chambers are separated with 1" Armaflex and don't make contact, except at the corners where they are joined together. I was going to seal the joint with silicone and apply a layer of insulation tape......but, this still would not prevent the cold temps inside the chamber from transferring through the joining metals to the outside. So, now I guess the two metals will need to be separated for a thermal break. I will use 1/8" seal tape between the two metals to break contact. Hopefully, this will do the trick! Thanks for pointing it out.

As I stated in a previous thread....the lexan that I will be using is multi layer laminated glass, which acts as a thermal break between each layer. So, I shouldn't have a problem with heat transfer to the inner chamber.

As far as regulating the pump pressure....the pump has a built in pressure adjustment.

Thanks again

it does? how does it do that? I would have thought that the pressure the system ran at was dependent soley on how much restriction the system provided, unless you introduce a restriction (Pressure sustaining valve, orifice plate, or a manual valve partially closed.

Keep up the good work

[generalpetres]

any more updates? i really do like your setup and youve helped me decide on building my own custom case i mean why buy something when you can make it to how oyu want it. any good luck on the rest of the build

[Sweeper]

Its been a busy month at work, due to the Holiday's and haven't gotten much completed on the system....but I have been working on making some parts in my spare time. I will be working on the motherboard tray and wiring after the Hoilday....so hope this thing will come together soon. I have manage to complete the liquid distribution system for the cooling chamber....

What do you guys think of my design for distributing the liquid?











Hope all you guys have a Merry Christmas and Happy New Year!

[CyberDruid]

It's looking very industrial--yet sexy :

Merry Christmas to you too

Do you plan to cool the sides or the top with your HDD block?
One great side cooling custom block AussieJester Made.

[TopherTony]

is it wierd I got a chubby looking at that? :/

that is great, you amaze me everytime you post an update

its not recommended that you cool your hds down that low due to errors that can occure etc its best to just put a passive or acting heatsink on them

[AllAgainstPaul]

5. The third cooling system will be a water loop outside the cooling chamber that will cool four hard drives, due to hard drives do not operate well under low temperatures.

I was referring to this loop when mentioning AussieJester's HDD Block

water cooling it like this would be fine but not what sweeper is building temps are going to be -0c which isnt to good for the hd. if you want to spend the money on a set up like the one you posted that will do fine

The hard drives will be cooled from the top side with a single closed loop water system. The heat will be removed from the water with two fans and radiator outside the low temp cooling chamber. The water block will be between two hard drives assembled together. I have two water blocks, so they will be looped together for cooling four hard drives.

As they say....picture is worth a thousand words.

[Fujimitsu]

Very clever with the HD blocks man.

As far as the distributor... simply amazing. One question though: Why copper? It looks amazing, but won't the copper just let more heat into the loop? On top of being more expensive? Other than face of the blocks, wouldn't you want everything made out of a good insulator?

Sweeper, your sheet metal fabrication as well as various other skills are just flat out amazing.

MMM! Just saw this and subscribed!

Those old Polarflo HDD blocks are solid, but do not interface with drives well. What do you plan to use as a TIM?

Merry xmas as well!

I was planning on using heat conductive thermal pads between the HDD and water block. I've found a few on the web...but I'm open to suggestions.
