i am not pushing this on ppl i am just showing an exsampel of how i did it

the 4" abs pipe holds a cooling elemt inside it the element is srurounded by water top barb is hot return and botom barb is cold feed to pump the fiting on the botom left is the sensor houseing tube

sensor in the tube monitors temp i had it set to a buncha difrent things but most reasent is 14c low 19c high meaning when water hits 19c compressor comes on and starts makeing the cooling elemt cold it takes about 5-8min to go from 19c to 14c once it hits 14c my controller turns the compressor off so the water is never hotter then 19c and never colder then 14c

now if one wanted he can chnage the setting on the controller and go subzero but u will run into condensation problems

rad in fridge will ultimitly =Big fail due to fridge and and freezer not desingd to carry the load and in a slush bucket temp controll is almost imposibel so condensation is alwayse a problem

THIS HAS BEEN DONE.
There was this guy on here, who accomplished cooling with a freezer.

His temperatures were great, and he ran it for DAYS.
It was inconvienient, so he took it down, but he ran into no problems for the time that he ran it

Now, one will argue that "it will die soon".

I'm not going to argue for or against that argument
.
Understanding the physics, it seems a fear analysis, but I will just throw in the mix, that the arguement "it will die in no time" is just as much theory, as was the rhetoric that a freezer cooled system "just couldnt work" - which this guy disproved, for longer than most argued it would take to be disproved.

If I do a search, i'll find his post and the pictures.

simpel test to se a fridges limitations or a freezers heat up 2 L of water to 45c and place it inside the fridge or freezer have another 2L of water reddy and heated to 45c as well take the first botel out and place the second one in after about 5 min do this for about 2 hours and u will tripp the compressor overload protection

why will it trip the compressor over load protection ?
cause a fridge or a freezer is desingd to keep things cold not make hot things cold so the condenser on the back of most fridges will berly move 100W of heat wich might work coling a soket A chip but anything over a singel core will overpower the fridges ability

what happens when u put a heat load on a refrigiration unit that cant handel the load well it will cool but it will do it ever so slowly ,now since the condenser cant disapate the heat of the extra load the refrigerent will compress at a much higher preshure and make even more heat till u eventualy tripp the overload protection

now if u find a fridge or freezer that can pull the load u still have no acuret way to control ur water temp , why would u want to controll ur water temp well when u go 10c below ambient u will run the risk of condensation

but hey if anyone wants to try it who am i to stop them

This is a concept that I have recently been delving into. It started off innocently enough with chilling the rad for my cpu water cooling unit. It has now ballooned into something completely different. My base was a compressor out of a vending machine. This compressor unlike our home fridge counterparts are designed to run 24/7 w/o shutting down. Currently I have been experimenting with it for the a month now with no issues. I have put the entire setup in a well insulated area and can run 24/7 with all temps in the teens celcius while the cpu is running near 0c unloaded. This has of course now started to create some issues with condensation. So now I am in the process of designing a system that eliminates this issue.

Am debating building a box that I can purge of atmosphere and thus eliminate the water vapor but that is just a thought I had today actually and need to do some more in depth research and design work on that plan. The second option is to again build a sealed box and fill it with a nonconductive fluid and chilling that.

What I would like to do is either go completely water cooled in all areas and using a direct heat exchanger in place of an evaporator. This way the condensation can be more easily controlled with normal insulation methods. The second option is to build a direct die system for all chips. The latter is far more involved and I think could prove hard to balance but ultimately more effective I think.

So far with that I have done I have noticed I can clock a little higher and remain stable even with the crap board I have that is notoriously hard to work with (p5n-t yaay for stupid moments in life) Good news is I don't overly care if it dies so experimenting is easier. (once it does getting a i7 system so kinda eager to push it to the limit) Hopefully after I find the optimal cooling solution though.

gildadan you're just a plain crazy lier n00b to OCN.

That CANNOT be done!

OMG I can't believe this thread is still going. lol I'm glad to spark up some discussion though.

Now if we could just find a theoretical compressor that would never die....

I'm interested in that guy who ran the experiment I was telling u about.
I'm interested to see, at least how LONG it would last.


--EDIT---

Oh, hi OP!

That's what I'd like to know as well. I've seen it done. I want him to run it to ground and tell me how long it took to die.

Someone needs to just get a refridge unit,disassemble it,take the evaporator and mod it to the water radiator in a closed air loop in a push-pull config.Would it be worth it? doubt it,but it would work fairly well.
