camouflage has finished his latest cooling project (large pics inside !!!)

[camouflage]

After returning home from my holidays I took some time now to make some pics of my new cooling system finished end of January.

I decided to use two water loops with two pumps cause my Nexxxos XP hiflow waterblock has only a flow of 300l per hour - but the chiller requirers a minimum of 1000l per hour.

So I bought a second Eheim pump with a max flow of 1200l per hour for the chiller loop and use my old one (600l per hour) for the system loop.

The tank is usually thought for use in a camping van - but a nice choice for me - capacity of 30l, filled with 25l demineralized water and 5l G12 anti-corrosive.

Using the tank means I can swich off the chiller at the desired temp and have still cold water for about one hour.

The core temp in idle stays always 6°C above water temp - I can set the water temp 10°C below room temp without any condensation - even more but didn't try so far.

The two additional 120mm fans keep my SB & board cold and help to avoid condensation inside the system.

Here're some pics now:

Very nice! I'm guessing that is a huge aquarium chiller? That emergency cutoff is crucial, you need flashing red lights and a klaxon also

[Fr3akyPete]

That is one smaller aquarium chiller.
Cooling capacity is 395W.
You must have bought it from Aquatuning, because you've got "AT custom made" connectors for the chiller.

I hope your chiller-top doesn't crack.

Yep - bought it from AT - top won't crack, I use that special kind of tape what nomally is beeing used to fix a mirror on a wall for connection and the weight of the system case is spread onto the edges of the chiller case.

[[XC] 2long4u]

I have that same case!

[Fr3akyPete]

Hey camouflage!
So the bigger Eheim, I guess it's an Eheim 1250, is only for the chiller, tank and CPU?
Is your "system loop" just for the NB?
Btw, is it a 1A-Cooling-Station for the 1048/46? I bought mine 5 years ago...still does the job in my lan-pc.

If you would insulate the tank with Armaflex or so, the tank could hold the temp even longer.

Yep - the stronger Eheim is a 1250, but the CPU is not in the loop cause the waterblock I'm using has only a flow of 300l per hour. So the 1250 only pumps the water from the chiller into the tank and back.

The other one (right - from 1A cooling) is a 1048, pumps the water from the tank to the CPU & NB waterblock and back into the tank.

I had to modify the bottomplate to fix both pumps on it and used some armaflex to avoid vibrations to the tank to keep the noise level low.

Indeed - the only thing I forgot to do was to insulate the tank, came to my mind just after I had finished the build. But now the 30KG tank is hard to handle and I don't want to get the water out of it again. Maybe I'll do it when I have to change the liquid next time.

Hi there!

Check this thread out: http://www.xtremesystems.org/forums/showthread.php?p=2807224#post2807224

Maybe you can throw some light on the subject (ie usage of Hailea Ultra 1500 in a liquid cooling setup), as I see you have been using a similar unit in your setup. Discussion over at the abovementioned thread (started by myself; although I unfortunately misplaced it in the liquid cooling section instead of the chilled liquid cooling section... ) have been fairly hot due to several reasons:

People in the thread cannot understand that a unit that only draws about 375watts can move/dissipate about 790watts. They also think the unit is overly expensive (although at a price LESS than 3xPA120.3 with fans) and that the high flow rate (minimum 1200LPH) would require a MASSIVE pump that is not practical for most users. I had a hard time arguing as I am not familiar with chilled liquid cooling (and the science of refrigeration in which some have elaborated in depth), and people have been called trolls/dumb/stupid/idiots and other inflammatory statements for considering such a unit in a liquid cooling setup, as it's also originally an aquarium chiller.

Anyway, have a look in my thread and feel free to comment / enlighten... but I would bring some heavy armor too, just in case

[flesheatinvirus]

If those specs are correct it should work. It can be found in reef tank supply places under Hailea HC-500A, it uses a Titanium heat exchanger with a R134A 1/2hp comp at flow rates of 1200-3000LPH.

[eva2000]

Nice always wanted to try something like this..any tips ?

what's the emergency lever for ?

[polar bear]

And is a huge reservoir necessary?

[flesheatinvirus]

Perhaps a well insulated 1-5 gal res to slow the curve down. A MCP655 inline pump would give you about 1200lph flow rate which would work with this chiller though Im unsure of its durability longterm running cold liquid.

[polar bear]

Thinking to use the biggest Hailea which is certified for up to 790watts to cool CPUs in both of my systems (#1 and 2 in sig). Ie I would then probably use a Y-piece to join both loops to hook up to the chiller, then Y them back into their separate loops again. Would then have a D5 (1200LPH max) in the one loop and a DDC Ultra (600 LPH max) in the other. Not at all sure if this would work, though

[camouflage]

I named it "emergency lever" just for fun - will need it if I have to change some parts within the loops to shut off the water flow before loosen the tubes.

It also will work without huge reservoir but using it You can shut off the chiller at the desired water temp and the water will keep cold temps for a long time.

[Griff]

Great project camouflage, just the inspiration i need to help with those summer ambiants. Just aquired a Hailea HC-500A off ebay for £200..


The "emergency lever" had me worried too

[polar bear]

Actually the prospect of using one of these units is tantalizing... thinking to perhaps use it to lower temps just below ambient to avoid condensation.

Would it be possible to use one of these to cool BOTH of my CPUs? Ie joining the two loops with Y-piece into chiller then perhaps reservoir then Y-tube to divide into separate circuits. I have a DDC ultra (600LPH head 4,7m) in the Q6600 loop and a D5 (1200LPH head 3,7m) in my E6600 loop.

Problem with this might be different flow rate and also of course resistance in each circuit. Is it feasible though? Any comments on this? Perhaps running an Eheim 1250 after the Y-joining of the 2 circuits to boost flow rate? Mind all this is just on the idea level - need more info first.

[flesheatinvirus]

I would think its still feasible even with a certain amount of flow resistance for a real 1/2 hp chiller to handle that sort of heat load without issue provided you can keep a solid flow of at least 300-315GPH. Use a nice insulated tank and just tap feed/return loops for each source and a seperate evaporator loop through the chiller just like the big boyz. Im doing one right now for a client that is a 200 ton Dx twin shell and tube evap chiller with multible feed pumps all computer controlled, they wasted one barrel and flooded the entire reciever and screw comp right to the top with water.

[ownage]

Interesting, any specs of the system (cpu vga) and cpu load temps when overclocked?

Is it noisy?, i'm thinking of buying the 395w version after the summer.

The system looks really neat with that chiller

Found an Hailea review

OK so a tank/reservoir is recommended. And I hook each loop up to this, inlets and outlets? Any info/threads on how to attach barbs to the tank? Then one loop for chiller->reservoir as per the way camouflage has done it? Is that the "evaporator loop"? With a separate pump with enough flow through the chiller I guess. Any threads on this?

Wow, that's a lot of questions but I have never done anything like this before and it sure sounds interesting.

Oh, and where could I get the insulated tank? I've checked pretty much all camping equipment stores online in my country and no...

Hmm getting bit dizzy at all this new info

[flesheatinvirus]

Camo did an excellent job with his chiller build and should be able to answer a lot more of your questions but yes a res tank is recommended. Most people here just find the right sized portable Beer cooler and drill and mount feed lines into it. One way of doing it is One side of the cooler has the feed supply line to your sinks and the outlet supply from the Evap circuit while the other side of the cooler is the return line from the sinks and the inlet supply to the Evap. Two pumps one for the chiller loop and one for the heat sink loop.

Nice tanks can be found on EBAY:

This is EBAY Germany but I think there's a big choice also woldwide....

awesome project.... cant wait til i get into the water chilling world.

[camouflage]

Did some runs at 10°C watertemp, roomtemp 21°C - no condensation !

The tubing is not the problem but I was afraid to get condensation on some metal parts (waterblock, etc.). But it seems the 120mm fan blowing to the mobo's socket section helps a lot to avoid this.

nice work Frank, i love it
how clocks your magic QX on it?

nice work Frank, i love it
how clocks your magic QX on it?

This way:





Didn't want to push more volts to avoid damage on the chip - but I think with ~1.62 a 5GHz 1M would be possible on chilled water .

Sadly the QX suffers like almost all quads from the FSB limitation. It's bootable up to ~460. So I just got me an E8500 to push my FSB a bit more ........, but I will post it later in a new thread - just wait a few hours, good things are going to happen......
