Oh well that kind of throws a monkey wrench in the plan.Have you considered patching it?I am remembering someone who used a very large chest freezer and filled it completely full of antifreeze and it leaked as well, but he patched it.I dont think he had any problems after that.

Nice idea to go by the evap pipes , I'd be a bit concerned I might break one.. I'm a bit hamfisted and maybe couldn't get duct tape on fast enough before all the gas escaped :)

Just tie strapping the pipes to the evap pipes was a cheap solution that probably wouldnt have worked well with a heatload.I was just messing around with it, there are better solutions.And if the evap pipes are anything like the pipes in this freezer, they are made out of very strong metal(seemed like steel actually) and breaking it would be hard, and if you did thats all she wrote.The ideal solution would be getting the evaporator coils bent into your reservoir to cool the solution directly.But that may be harder than it sounds.

Thanks for the advice guys, I'll definitely try both of those at a later date once I got it all up and running "standard" on an actual chip ( my AMD64 is out for the count at the moment ) . I don't want to mess it up by tweaking before I actually get some use out of it, that would be a shame ! Both ideas seem within my capabilities though, so that is good news.

I was thinking about my plastic container whilst at work and noticed my paper bin sitting there, which is metal. That would definitely be an improvement, but of course it is still round, really I need a square bin so two sides can touch the sides of the freezer. Rather than 24 hours I need to have 8 hours between start up and the liquid getting to coldest. This will let me bench morning and evening.

I have been looking at thermometers and to be honest Fluke etc are out of my price range for what I need it for , I saw this one

http://uk.farnell.com/jsp/catalog/vi...prodId=7105769

Any thoughts ? It goes down to -50C ( though at reduced accuracy ) which will be ample for my setup. I assume it is a thermister type , any disadvantages to that over a thermocouple ( thermocouples seem more expensive!)

Well I pretty much finished this post, and forgot I was stress testing this piece and of course it crashed. Well starting over. I want to make a chiller of course. First of all I have NOTHING at all to begin with (except the puter :p: ). Now for the water cooling system itself I was going to go all from one place, dangerden. I want to get RBX block chipset block and Maze 4 block for GPU . All this would be copper, not loctite. For a resorvoir, was thinking like something Jamal has, square and not to big. And of course Tygon tubing and lotsa insulation.
This is the AC http://www.maytagair.com/units/m3x05f2a.asp . Cost 98 bucks at homedepot. Would this do the trick? Thanks :toast:

it would probably do fine , the thing you can't tell is how the copper lines are running inside . They need to be long enough to get the evap into a res . Before buying one I would ask friend or family if they had an old unit laying around for cheap, or free. I have an old working unit you can have if you want it but its kinda a pig, its big, loud and draws 11 amps. if you can handle this its yours for haulin it off.:D

You guys would be just amazed at what you can do with a tubing bender. :D

Hey, I gotta couple questions about the AC unit. Whats the typical amperage it takes for one of these? you say that one you have takes 11 so im guessin a newer one would be alot lower? Loud doesnt really bother me, I sleep with 3 vantec tornados in my room lol :hehe: Is there a water block for the cpu , nb , gpu that anyone would recommend? and maybe also a pump thats recommended?
Thanks :toast:

Hey, I just saw a 24,000 BTU unit on ebay for 100 bucks and looks new, and its a window unit. Would that cool more then a 6000? or does that just do something else? I was thinking that it just cools down faster, but not really any colder?

I think you would be correct, it has greater capacity for cooling, but cools no colder.

I got a 10k BTU unit free, and it came with a 1 HP compressor. I think thats really too big for a computer setup (750w running 24/7 in a closed room isn't too much fun for your room temp nor your electric bill). A 24k unit would probably have a 2+ hp unit (~1.5 kilowatts).

Being 24000btu its more then likely 220v, check the amp draw.
Basicly a 110v & 220v motor of the same hp the 220v will draw 1/2 the amps. It probablely would'nt get any colder but recovery
would be alot faster. :cool:

A 6000 BTU compressor is 1/2 HP. That's more than enough for everything on your computer. If you want fast pulldown, put a TXV on it. The smallest TXV's are too big for a CPU direct die, but are just right for a chiller that is cooling everything in the computer. These A/C chillers rock. We haven't shown what these things are capable of doing yet. :D

My AC has to have the worst design ever... Super small suction line and all :(

Jamal is seriously considering fine tuning the refigerant. Im going to join the chiller game also and im copying him :hehe:

Direct die systems are more popular than chillers, because we haven't seen what a real chiller can do, yet. You lose a few degrees in the extra layer of heat exchange, but you gain a lot of advantages.

Multiple blocks, no problem. Upgrade blocks, hoses, pumps, no problem. Add more blocks, no problem. De-humidify and cool the case, no problem. Disconnect it, move it, and reconnect it, no problem.

And then there are cascade and autocascade chillers, not to mention full submersion.

Chillers rock. :D

Yep because you dont have to you dont have to worry about an evap block :p:

What do you do for a pump bellow -40C tho?

There are such pumps, expensive though.

Im grabing an ac unit probally next weekend and getting mine done FOR SURE!

Hah peen is a luckey man :D Well I want to do this as a learning expirence to. I got my compressor so when that gets here I'll finalise my plans and order the rest up from rparts :D
