I was wondering if anyone here has used a freon cooling system, I have an old fridge and I want to get my temps below freezing, Ive read abut it a little bit, not much different than water cooling.

You hae to be some sort of certified thing-a-ma-boob to use that. Apparently a fridge doesn't have the capacity to deal with the temperatures generated by a computer. Talk to iateronmly for more information. He's a certified thing-a-ma-boob.

just a quick note: it's not that it doesn't have the ability to deal with the temps, it's that it doesn't have the durability to run constantly. fridges are light cycle compressors, so if you had an old sub-zero or something, you'd be good to go

Talk to LoudDog too, he has a refrigerated computer (it's IN the fridge)

It's a matter of BTUs - a present day CPU releases over 100 watts overclocked (or stock in the case of Prescotts). A full refrigerator MIGHT have enough power to take care of a CPU if that's all it had to deal with and not the over all heat produced.... but there is a catch - duty cycles. Residential refrigerators are designed with the thought they're going to maintain a low temp not deal with a constant heat source, so they don't need to run 24/7.

You can split the difference and place it in a freezer as someone else has done (LoudDog is the one I think). But from their description they don't leave their computer running 24/7 folding either - they have a large vat of coolant to help compensate.

Anyways, who in the heck uses Freon anymore? The stuff is over a hundred bucks a lbs USED and good luck finding new bottles not recovered in most areas. At work we have one bottle left, and it was at a large premium.

If you're goal is to make your own direct die phase change system (not to be confused with direct die watercooling where the die is exposed.. this refers to refrigerating the die alone and not the system). To even legally attempt it you first must hold an EPA certification card. Then handy skills like brazing come into effect, you'll need a compressor designed for 100% duty cycles.... buy refrigerant.... if you're not going to use 134A which can be bought in small charges at the autoparts store, figure over 100 bucks for a bottle of "whatever" (but you'll have enough to last you a few decades).

Basicly what I'm saying is this - unless you know what you're doing, have the tools, buy a Vapochill or Prommie (before they're all sold and gone). You'll be farther ahead and don't have to risk playing with refrigerants that can act as nerve gasses if released or litterally burn out your lungs if they go acidic from to much heat and inhaled after a leak.

This folks is why I still run air.



ADD: LoudDog's comments about his set up:

I can pretty much use this computer on and off throughout the day so long as I let it cool for a couple of hours periodically when it's not in use.

I figured I should make the following comment - Johnny English's Law (like many great computing laws, such as Moores Law) is proven yet again. 2-3 months this question is asked.

CongratZ JE for supplying another great truth to computer modding.

Well right now I have acess to r-134a the safe coolant used in cars as I am a Hot Rod technician and I am licensed to refill this refridgerant.And Im talking bout using the direct to die method not just stuff my rig in the freezer.Im going for full mod effect.I want to mod the fridge unit like a case.and I know things get repeated but almost every situation is unique to that person.

Iater pretty much explained it above, nobody uses freon anymore. However, phase change cooling is becoming much more prevelant. Check out this PR link to see it in action:

it can be done i recomand a gutting dehumedifrer. i did it once but had problems with moister when i would turn off computer. most use a small a/c unit in them to collect moister but the condenser and evrapoter coils are in the same unit so the unit normaly doesent get cold but they have small coils small compressers and and most are easy to take apart w/out cutting any copper and made to run 24/7only problem was keeping the condecing coil from getting hot also if you do cut a ac out u can use some 134a found at auto zone and wallmat to fill up a smallone for progect use as long as you dont fill it up to full pressure as the old regefrent becouse 134a opprates at a higher pressure. o ya never add on the high side ot the compressure

thanks for the ref to the article, that is a much easier solution to what I was trying to accomplish. I didnt want to ruin any hardware or be down from folding for to long. The home boss wont like it, she says I spend too much anyway, she says "you just bought that" well its not my fault its out of date. Oh well thanks BA.

WHOA there HOSS!!!
Never give advise like that to anybody man.
First off Phase change cooling is left for the pimps that want to constantly be in the case.
Second off screwing around with a compressor and condensor, evaporator, drier and filters is not for the uninformed.
THIS STUFF CAN KILL YOU!
You have not a clue as to what you are talking about. There is a whole lot more to it than you even think...
Be safe and not dead!...Zennz

Purchase a vapochill unit or mount a window AC unit into the side your pc case.

like I said Im qualified in 134a in car systems and understand the high and low pressure side of things Im just trying to find an economical way of doing it. And weighinging my options the vapochill is the best bet

Look at the VAPO-CHILL Light speed, It has a capacity for high wattage load and is 110vt compressor, with r404a for refrigerant.
