im trying to make a refrigerated pc.. its been done but it has a price tag i couldnt afford in a couple of decades... the principles are fairly simple to my knowledge http://www.go-l.com/_images/coolingcycle01.jpg
but i still need help since i only know how it works but not how to build one... only two problems that i can see... condensation
http://www.go-l.com/_images/cpukit.jpg http://www.go-l.com/_images/maincooler01.jpg
since that would ruin the parts... and keeping the temp at a certain point (maybe a thermostat?)... i have access to most parts and labor wouldnt be a prob... heres wut i want to do...

heres a link to the cooling page (http://www.go-l.com/desktops/machl38/cooling/index.htm) from this particular computer...

can anyone point me in the rite direction? or gimme some design notes? all help would be greatly apreciated.. and this way i will also learn more about refrigeration :)

well thanks to all who check the post... sorry about my spelling not a born english speaker... (if pic dunt show enter the page then come back and they will... i think)

two sistems ive found...
the first one is the one inside the pc i show ya guys in the pics..

VapoChill (http://www.vapochill.com/main/page.asp?sideid=388)

and this one is a copy of the biggest system from vapochill but this one goes outside of the case... and is bigger but i didnt find anything else other than retailers... and it uses a dif gas r134 something ... (ie crashed on me :confused: )

condensation is a real problem and they usually silicone thr board to prevent this

try this discussion board

i actually found pics of the vapochill... they use a kind of thermoelectric device(peltier) but on the other side of the motherboard.. also the copper that is to be attached to the processor is covered in some kind of foam on the sides ...

Not wanting to knock all those that strive for the ultimate processing speed but I am at a loss to see how increasing the cpu speed can really make that much difference - given all the time, expense and problems concerned. If it was simple surely Intel or AMD would have solved it by now. What about the slow speed of the FSB? how do you increase that? or the RAM speed - this is fixed for the type of RAM fitted

Obviously, you can tell I'm not a speed freak :p

Confused :confused:

Hi Frank
I think that the processor speed is in direct proportion to the temperature in which it works. I think I read somewhere that if you halve the temperature you double the processor speed. :confused: Like you though, I think that the lengths some people go to reach these speeds can cost a bomb. :eek:
Is it worth it I ask myself :(

To prevent condensation -as you can see on the pictures - they install a flexible heater 12 V-5W on the outher side of the isolation.

ok but why? :confused: :confused:

Why..??? :confused:
I think motherboards can't withstand constant dripping condensation water onto it.
Electronics fears water I always thought.

erm.. not that hahah... why does that heater solve that...

The heater raises the dew point temp so water from the air do not condensate on the motherboard.

Here is an organization that has been quietly working on liquid cooling of computers and electronics for several years. We have supplied the liquid refrigerant pumps and some of the engineering; Scroll down to Joe Marsala for a presentation (address below)

Hey there , water vapor and condensed water may shortcut the circuits on the board as they can make some current leaks from the ICs "Integrated controllers" which perturbate the fonction of the board that's why the motherboard controller should be protected against high moisture and water condensation and dust.

Not sure if you are responding to me with respect to liquid cooling of electronics. Your concern for water vapor condensing on electronic components is well founded. The web site that I refered to shows a working proof of concept enterprise type computer having 8 hot swapable mother boards. These boards were designed to be liquid refrigerant cooled. Condensation never becomes an issue as the sytem always stays above the dew point of water vapor that may be present in the computer or electronics cabinet.

I will soon be finishing off my system. Pics below. To combat condensation on a DIY system, socket heaters are not required. You can use grease around the CPU pins, and the back of the motherboard, which will reduce the chance of frying your components. Good Insulation is a must.

I won't explain the whole insulation process, I will link you to a guide(s). Basically what I am using is Neoprene, and dielectric grease

Lo to all, newbie alert :)
For the DIY user liquid silcone that cures hard is a must, it will protect the motherboard forever against condensation problems.

I am the moderator at Vapochill.com support forum, I am not so much into the working of phase change, more the working of a PC. If anyone needs help overclocking please feel free to PM me.

As for what Frank said why overclock? It's abit like why tart your car up? or why race F1 cars around the track that need rebuilding each race? It's all about who's the fastest, highest clocks high scores etc. It is good fun, feels good when you see windows spring into life @ 5ghz or 3.2ghz using a FX-55. Running 800mhz core on a X800pro Vivo (stock 450) and yes it does make a big difference, very noticable.
:D

Confused :confused:

thats a bit like asking a world record holding sprinter why he wears that silly lycra, just makes him look stupid.... but makes him run a little faster!

when it comes to a World record, no matter what its in, some one will go that little further and try something new.

and for the normal people amoung us... spend 300 on a unit.... have a 50% increse on speed of any comercial processor.

not hard to under stand,

and intel and amd both understand that 'ecessive' cooling is benifial as intel where 'thinking' about releasing processors with in built T.E.C's not so long ago.
