My New Chilled System.

[xxjoebreadxx]

Hey guys, as you may know My buddy Mat4541 just shelled out and bought a very nice danger den liquid cooling setup.

GTX 480 Rad
4 3000 RPM fans to go on it
Swiftech multistage pump
Danger Den 2 bay res
V-Tech
Fuzion D-Tek waterblock
and 15 feet of 1/2" tubing to go with it.

We spent all day hooking this bad boy up. Seriously, the Antec TwelveHundred was not meant for liquid cooling. It took some major work. Had to bend a drive bay...Drill holes for the pump and what not.

Anyways We boot the machine to see a nice above ambient temperature Proc (core 2 quad Q6600). She was running at a piss poor 30 degrees..(Did you get that joke???). Being angered that We both got under 30 with our air coolers we decided to try this.

Yes Yes, That is tubes coming out of a freezer. Yes Yes, we did put the rad inside the freezer.
It worked pretty well

Got into single digits.

After seeing that we went out and bought a 9x9 freezer from wal-mart for $64.00. We are currently modifying it to fit the rad inside. I'll post pictures as the build goes along.

wow, thats.... inefficent. dont mean to flame or anything... but before you buy that freezer, look into building a "proper" liquid chiller... i.e. rip apart a window ac and all that jazz. single digits is ok, but you can go sub-zero this way and ditch the rad :cool:

[xxjoebreadxx]

Nah I have a guy building me a phase change unit as we speak. My buddy just needed his liquid to get cooler and didn't want to spend that much money ;)

Already bought the freezer. It was only $64.00 from wal-mart. It'll work for what He needs.

[Noob-ftw]

That is really ghetto lol! You could look around and find a window A/C like I did. After doing some rewiring, cleaning, painting, modifying and whatnot, the 10,000BTU actually turned out to be a gem:

Before one of the chilled liquid pros comes in and lights your pants on fire for a slew of bad ideas, let me just say welcome to the world of sub-ambient cooling. One thing you can do that will work for short periods of time is to put a large reservoir of liquid inside of the freezer. You'll want to use a water/alcohol blend so it doesn't freeze. Your freezer isn't capable of constantly dumping the heatload from the processor, but you can use this large reservoir as a capacitor of sorts and run for an hour or two before the water warms up too much. This is a cheap way to get a few extra MHz for benching but not sustainable. Next step, get yourself a liquid chiller :up:

[KaptCrunch]

thats great for short period of time for low btu's out put for general freezer operation (sealed insulated compartment), while A/C unit starts 5k with no insulation and high ambiants. Zen is right better off with A/C unit

[xxjoebreadxx]

Idk? The way were putting the rad in the freezer the lid closes and its fully sealed. I think it should be alright. I'll leave it on overnight and see what temps it hits. I'll post what happens tomorrow.

Telling ya man, get yourself a big jug of water and give it a day or two to be pulled down. Hell, if it's a top-loading freezer just fill it with water and alcohol and drop your hoses into it :D

yup, fill it up and let it bring it down. The more liquid in the longer it will last but I really would look into an AC chiller. I love mine and I could use it 24/7.

[xxjoebreadxx]

So actually use the freezer as my rad? I never thought of it but that might work. How would I go about sealing the freezer?

[KaptCrunch]

here's a pic to give you an idea, punch drill hole if to big use expandable foam to seal it up

[Asgard_thor]

nice crunch :P

[Xeon th MG Pony]

epic fail, sorry but there is no redeemable way to say it for how bad thats going to work.

As another said, fill the freezer full of water, let it run a few days till the sides have 10 to 12 Inchs of ice on them then run that through your system, you'll have about a couple hours of loaded run time at 0c that way with out killing the freezer.

that or mod an old fridge compresser to a proper chiller.

most likely if left in bios it'll be well above zerro if in windows the fridge will be running 24/7 and you'll shorten the life if not cook the system, no matter what some thing WILL die eventualy and it will be the fridge, then computer in that order!

Please read the forums.

And fyi a snow ball in hell has a better chance of lasting longer then your current config!

[xxjoebreadxx]

Hmmm, As long as all the liquid is chilled first the fridge doesn't have too much of a load on it. The way everything is set up the liquid isn't getting all that warm when it comes back into the fridge. Actually the liquid is quite cool when its being pushed back into the rad.

KaptCrunch I have that same fridge lol. $64.00 from wal-mart. Can't beat it.

[xxjoebreadxx]

I don't know about that. A snowball in hell probably wouldn't last all that long. Probably only a few seconds... and my fridge has already lasted longer than that so I would say that that is a false accusation on your part.

guess it really depends on the time of year really...

I have a freezer from wally world myself. Interesting ideas! I'll have to do more reading on this.

How long is that coil inside the fridge? I have 15 feet inside my fridge but your coil looks longer.

[Xeon th MG Pony]

by precooling the water it just gives you a longer rise time, IE the precooled water acts like a dead rechargable battery charging, as you add energy the sensible heat will climb as long as you add energy. The fridge can move on average 150 to 300Watts slowely as you are going from gas to air to plastic then water as the final moving mechanism.

the fridge concept is old and theroughly proven why it is a verry bad idea. I say it is a bad idea as a hobiest, I say it is a bad idea as a lisanced technition, I say it is a bad idea as a person with good common sense! you are welcom to find out for your self how ever.

[xxjoebreadxx]

Your right. The freezer will keep the liquid cool for a short period of time before it warms up again. We can tweak it to keep the liquid cool for a decent period of time but its not as good as I want it to be. What do you recommend?

[malkiewicz]

Wouldn’t copper radiators work better than rubber lines inside the refrigerator or freezer…? IMO metal rad would absorb a greater amount of the refrigerated air than plastic or rubber - thus cooling the liquid faster…. Just a thought…

[Xeon th MG Pony]

If you had a deep freezer and allowed it to form a thick layer of ice on the sides then directly pumped the water through from it you would get good length of run time and allow it to build ice again as needed. thicker the ice build up the longer your run time, same goes for the water, more water cooled the longer it takes to fill the water up with heat.

and the invers is true, will heat the air in the fridge faster over whelming the compressor! either way a fridge simply can not handle it as is.

[RussC]

There are a couple of reasons why that fridge system don't work that well, first is they don't work like your regular fridge in your house. If you change that evap to a finned copper radiator and put fans on it, it will cool much better and get more of the available power to the system. Thats why your house fridge works better. That will help alot and increase its effciency by 30-50%.

That fridge is just a really small system anyway, dump a larger compressor and condensor it will work much better also.

That was my first D-Ice Water Chiller ;)
