is a phrase change system quieter than air cool?

[LandShark]

will a phrase change system runs quieter than a mid-top-end air cool rig??

also, is there anyone know who carry Prometia (sp?) in usa??

how 'bout the new Vapochill Preimiun Edition?

this will be my first extreme cooling experience if i decided to go phrase change. so, lots of newbie question......

tks in advance!!

I sure hope you are joking about this.. IT's not phrase change.. it's PHASE CHANGE.. as in the change from liquid to gas to create the cooling that happens in a phase change system. A refrigeration system doesn't put out cold.. it absorbs heat.. the lack of heat is why things get cold :)

The liquid in the evaporator absorbs the heat and boils off changing into a gas.. then the this cool vapor goes into the compressor to get compressed again.. going into the condensor to get cooled and turned into a liquid..

I wouldn't buy any pre-fab systems.. I'm a DIY'er.. but If I did I would buy the Prometia.. it's expensive.. but it actually gives results..

And yes it can be as quiet as a medium-top of the line or whatever air coold PC

tks for your reply.

heard Vapochil has the new Premium Edition coming out sometimes this week too......

the problem is i'm also into the "look" too. honestly, i'm not impressed w/ the Prometia case but the new black/grey Vapochill looks good......

do not buy vapochill they suck.. read my PM

Landshark,

You going before me. I'm just now starting to think about watercooling, hopefully I can learn some extreme cooling as you go.

NOTE 1, hipro5 currently OWNZ the seti benchmark, and he is on a promeita system I believe. Expensive, expensive, but tempting, tempting .....

NOTE 2, are you on watercooling already?

Has a switech waterblock + peltier all together. Looks like (to this noob) that if you already have water, this is an easy way to add a peltier, kind of an easy introduction to test how far your CPU might go .......

Good luck, let us know how it goes.

self made phaze coolers can dominate a prefab any time of the day. the system im working on will keep my case temp at -86C and depending on what i finaly decide on for a refridgerant mix -115C to -170C

Yeah if you can find those small 150hp screw compressors that can actually condense methane ;)

[IceFoundry]

SSJ, You know if Methane will even work yet?

[ssjwizard]

yes methane works and im using a gas mixture... most commonplace refridgerants are methane based of course it works. i dont have the exact condense point YET but i will be finding out soon. the places where i shop for my gasses(verry large companys) try to keep there web idiot friendly by listing only the nominal data. liquid condensing point is out of the range or a normal persons need for information. but i can tell you that it is not extremly high thoug it is far above average more like twice the psi's required to condense.

Well if your gonna air condition your case down to those temps you better have figured some way to stop the air getting anywhere near it because you would be freezing the carbon dioxide right out of the air. The inside of your case would soon fill up with dry-ice. At -170C you are pretty close to liquifying the oxygen and nitrogen too.
You also better think carefully about the materials you use to build it out of, most metals are so brittle at those temps if you sneezed you would shatter your system into a million pieces.

[IceFoundry]

buwaahahah.. If you sneeze you will shatter your system into a million pieces.. heh
that's so funny.. probably true too..

Could you imagine that? like.. your cat comes and farts by your computer and a junk of metal their falls off.. lol

chances are any prefab system will be louder than a normal non oced pc, but if you make your own, having a huge condensor(can even have a passive on) then have your return line wrapped around your compressor(or a additional waterloop) and then insulating it could make it almost silent.

ssjwizard did you think about the condensors on your motherboard, dont think it will work if the motherboard/case is cooled that low, octools.com had done a a total system submerged and cooled the liquid to -40c and anything colder the motherboard wouldnt post(or something on those lines). One option would be to unsolder all your caps and extend the wires and put them in its own container, but i dont know what that would do tothe stability.let me know how it turns out.

[ssjwizard]

ok the case obviously wouldnt be anything premade and ill probably be using some kind of dual layer so that the frozen layer cant be contacted. there wouldnt be that much co2 inside the case so dry ice wouldnt be a major factor. i do plan on taking precautions for the system. as far as the mother board not posting below -40C well lets just test that shal we! if it doesnt it can easily be ajusted to run at a higher temp no problem.
