People, people! Christ, I haven't said that this will work. I said I think this will work, and we'll see. I'm open to every theory, and what most of you said about that the fridge won't be able to cool down the computer, and not even the CPU.
I believe it's true, since the fridge is all sealed up, and after a while, the components will burn out. But I was thinking of something to push out the old air, without any air coming in (so there always will be low humidity). So that the fridge will never heat up. Since it'll be just as a normal chassis, only that this will have a freezer inside it.
Anyways, it's only crap that'll be damaged. Someone told me that I should try to have the fridge open all night, and see what would happen. Well? I've many times forgotten to close the fridge, and nothing have happened. But having the fridge open for a certain time, will damage the fridge.
By the way, I'm not saying this idea is unique, special, new or anything like that! Why do you all have to flame me for coming up with an idea for my chassis? I mean, I've never said that I'm the first who's gonna do this or anything like that. Seriously.
But thanks for your thoughts, and we'll see how it'll work out.

Kind regards,
Nymph.


but you throw a fit every time someone comes up with a reason it wont work. either go ahead and do it for **** and giggles or realize it wont work and dont do it. dont keep defending it like a child insisting that "my dad can beat up your dad!"

This statement just shows how little thought you've put into this project. Are you planning on creating some sort of vacuum-case void of any air? I'm not even going to get into the problems that would create because it's not going to happen. In order to "push out the old air" you have to have new are coming in - thus the entire idea behind standard air cooling. The problem with doing this in a fridge is that now you've just increased the volume of air in the total system, far beyond what the condenser can handle. I'm not picking on you for this idea because I, just like everybody else, had it at one time or another - but the truth is that there are real hard scientific facts as to why it won't work. Go ahead and try it but the very best you can hope for is to not completely burn up the system in a couple hours.

like probably everyone else in this thread i too have thought of this idea. you could argue about the cooling power of the fridge but noone seems to be considering the pump of the fridge.. they generally arent designed to run 100% 24/7 as when something is frozen, the heat is removed and so less energy is needed to keep it that way. The fridge would probably die quite quickly in this situation. not only that but roasted PC doesnt smell too good, you talk about letting air out and that its air tight... well they contradict each other you cant have it air tight if air is going to be removed.

if you want a good idea, try mounting the watercooling rad and even reservoir in there, the water should lose some energy on th way there so it has a higher chance of succeeding. especially if you put another rad external to the fridge so its cooled even further before entering the fridge...


If you do go ahead with this PLEASE PLEASE PLEASE post lots of pictures for the world to see. your idea will not work, freezers arent designed to cool heat sources, as someone mentioned earlier, your peas only have finite enrgy in them!

No, I think most people in this thread do realize this. Maybe we aren't vocalizing very well because it just seems so obvious. What the OP needs to understand is how a refrigerator operates and why it won't work for cooling a PC. Water is great for cooling to, but nobody would consider running their PC in a bucket of cold water.

Condensation is a huge issue.

1) Go to the junkyard and get an old freezer unit, not the freezer just the elements.
2) Get a small cooler as small as the elements will fit into…
3) Cut a small hole in the freezer and run a hose out.
4) Attach the hose to the CPU or into the case in general.

The whole system, fry’s from condensation!

Ah christ! I forgot that I need air in too, I mean, I thought the freezer would magically make new air -.-
Well, you've all convinced me not to do this, even not just for fun. I don't know, maybe I'll try it.
I still got the heatsinks and/or the watercoolers, though.

Kind regards,
Nymph.

Uhm, just wondering. Is there some freezer-like device that works like the freezer; "makes cold air". Without any condensation-f***ing-issue? :P

No, unless you run it in a vacuum. And not the vacuum you sweep your floor with. Vacuum like outer space, no air/moisture... As long as you are in Earth atomsphere you will have moisture in the air, condensation happens when the air comes in contact with a object that is cooler than the air around it. http://en.wikipedia.org/wiki/Condensation
You would have better luck using the fridge to build a phase change unit http://www.overclockers.com/tips1238/

or you could just umove to a really cold climate and stick some PVC tubing from your window > case intake fans like I did... I can get my CPU down to 10C (when its -15 outside)

That's what I did for the over clocking contest I was in but, I just stuck mine on the porch and closed the door as much as possible with out scrunching the cables.

Hee hee, no flame from me bro. I was just reiterating previous posts. Go ahead man. I'd like to see the results.

Without revisiting all of the other issues mentioned previously, there is also this: Even if this whole thing works, the refrigerator (a heat pump) will release into your room the thermal energy of it's compressor PLUS the thermal energy of the PC. With this kind of system, you can't cool something down without heating something else up - even at an impossible 100% efficiency.

On the plus side: you won't need a heater in your room during the winter.

On the minus side: your room will be uninhabitable during the summer!

First off, have you even read my thread? Secondley, if you have. Then you're just a smartass who have no plain idea on how this works and just go for: "Gee, what a dumb idea, but still I don't know **** of what I'm talking about...".



No your wrong. I DO have every idea of how it wont work....its a fridge for god sake, its designed for cooling food, not computer components. Thats what nitrogen/liquid cooling solutions for pc's are for. Let alone all the other problems of condensation, electricity bills etc etc. Why this thought has even been contemplated in your head is bewildering. What do you think you mates would say if you tried to get it to work? They would think you are a freek and a social outkast.......

There are many reasons on here why people have explained why it wont work, but still you are insistant on starting it anyway, so my question is this: Why did you start this thread if you have not even the slightest inclination to take someones advice??? If i was you i would not bother wasting your time, but its your time, so please, post pics of the ruined components/fridge once you've done it, tell use how long you wasted, and kiss my ass and listen to me say i told you so.

Thats why i think this is the dumbest thread ever on toms forum.

I have a degree in physics, and have been an electronic design engineer for a couple of decades now. I say to the OP: "Go for it!" At the worst, you will be out some old components and a refrigerator. That seems to be a relatively inexpensive lesson.

If possible, I'd recommend not cutting any holes in the refrigerator at first, so if you discover the experiment to be a failure, at least you won't have ruined the fridge.

Any day you can learn something new is a good day.

Why not just strap an air conditioner to your case? That would be plenty cool, and you wouldn't need to worry about condensation. Air conditioning makes air less humid.
