I mean, it's already used regularly in AC units in cars and homes, but what about a computer?
assuming you could fix condensation problems, and have a ready supply of it, (not really that hard to acquire, It's relatively inexpensive). And as well as assuming we can completely avoid leaks due to it's moderate toxicity, how would it pan out in effectively cooling a system?

No idea what freon is?
check out the Wiki page on it:

You basically asked a question but told us to ignore all the possible issues, and the reasons why it is currently not used. It's like asking, how would using chain link fence work as a roofing component instead of shingles, assuming you fixed the problem with all the holes.

Regardless, assuming that you mean Freon as in the actual Chlorofluorocarbon, it is banned in many countries and controlled in the United States (you need a special license to buy it). Not only does it deplete the ozone layer, but it is also extremely harmful if inhaled. And most modern appliances and automobiles do not use it.

Well what i was trying to refer to, was the freon you can get for your cars AC system at any retail store in the cans with the hose attachment bluit into the valve trigger.

Ah. Freon is actually a trademarked name used by DuPont to refer to their line of refrigerants.

 

[HoztileManikyn]

Oh, well then I misspoke. but yeah, THAT freon, could that be implemented?

 

[Lord Xeb]

Any refrigerant coolant can be used, however the REAL freon... no not so much. But yes, you can even use liquid ammonia. However, that stuff is... really bad. You breath in ammonia and will literally cause you to choke on your own fluids as it stole all the moisture from your lungs.

 

[Wihglah]

You are basically describing a phase change cooling system.

They've been around for ages.

Google "Vapochill"

 

[Lord Xeb]

Ah phase change. So much fun. However, some are loud, makes the lights dim, and can make even space freeze

you can expect power consumption to be higher than the heat removed. Compressor and fan on the condenser will add power draw, and even a water-cooled condenser with 3 fans on a normal evaporator (radiator-style) not even cooling room-temp air can draw about 200W or so, while not even really going sub-ambient.

So you can DEFINITELY do it, for sure, but whether the power consumption is worth it is up to you.

Thermaltake sold a case with a phase-change cooler built in, called the Xpressar. OCZ sold the Cryo-Z for a bit, and there's other brands still making phase coolers in various global locations. Yet, because it is filled wit ha compressed gas, shipping globally can be an issue.

 

[ejohnson]

There is also this. It uses r134 (freon) in a radiator and uses heat to vaporize it.

I have a few of these heatsinks from the old MSI media live units, but they are all amd setups so I have no way to test them.

 

[KYKYLLIKA]

Well… I am not sure about pumping it at these speeds. Refrigerator and A/C heat exchange is a rather slow process based on pressure changes or something like that. I don’t know much about it. Anyway, your chips generate large amount of temperature constantly, so you need to pass heat through some not-so-straight pipes into the rad. Is there a pump that can deal with that fake freon that you can safely put into a case? Are you going to be okay with the sounds it makes? I know my fridge says something like what a grumpy bandersnatch would once in a while.

 

[Ceadderman]

Why use freon? Shoot why not just watercool and run a single radiator through an ice bucket? Since "global warming" became an issue freon only goes up in cost and is the single reason R134 is the charge injected into most every refrigeration/cooling device manufactured today. Sure it can be done when implented properly, but why would you try a dying technology and change it over later?

A 5 gallon bucket, a radiator,flex tubing fittings and ice would do aa bang up job. Condensatin is minimalized to the external cooling source. ONLy way to go imho is phase if you want/need colder than ambient temps.

I wouldn't say that it was because of global warming, it's because of it's thermal characteristics that it is the most commonly used. And I'm not saying that to be argumentative, I'm saying that because this sets next to me:

 

[Ceadderman]

I speak from personal experience. It was indeed because of Al Gore's pack of lies to line his pockets. Worked in the auto industry at the time R134 was introduced as a viable replacement over freon. The latter being phazed out as a result.

Not taking your argument personally. It's a response to my stance and responsible debate is based on legitimate back and forth on any subject. All good in my book.

And I'm not in the US, so what Al Gore says has no relationship to what goes on here.

But I do get your point, since its inception was primarily to reduce ozone depletion since one chlorine atom can destroy a million ozone molecules. At the same time, r134a is nearly identical to r12, without that chlorine. Freon is just a DuPont brand name, SUVA would be the equivalent for r134a.

But I don't associate ozone depletion with global warming.

 

[Nnimrod]

Short answer, no it's not really got a use. We've been through this before.

 

[epic1337]

most refrigerants won't work well, you'd also need a large industrial compressor to cool an overclocked chip too.
to point out, most commercial AC compressors aren't meant for 24/7 continuous use, their compressors needs to idle most of the time.

what could be done is use a 4HP compressor, run it at 1HP 24/7 and use CO2 instead.
CO2 has an advantage of a larger heat output when compressed than freon, meaning you can cool it much better than freon.

 

[HoztileManikyn]

That's actually a good idea,
i might try to build one in the future
(as soon as i get to actually fund the project)

 

[Schmuckley]

hmm $75/lb ..supposed to not release it into atmosphere (all bs)
vs $48 for 35L of Ln2..
My vote goes to LN2
