    Most case materials such as aluminum or other materials on higher end cases atleast are meant to disapate heat quickly. Adding a layer or two of spray paint insulates the case material from disipating the heat properly. Most cheap steel cases or even large full tower steel cases of better quality depend more on fans and large air space to keep things cool rather than taking the material of the case into the formula as well

    If your case is next to a window maybe a mirror placed next to the case ? Cant get more reflective than that :D

    Non Conductive liquid

    Other than pure h20 is there any man made fluid or jell that is not conductive ? Because i want about 10 gallons of it to instert my case into :D

    i dont think you could physically run your comp in a pool of non-conductive liquid but a few drops wont hurt it :D

    Hi! Tedster - ambiant - no spellcheck. ;)

    I must agree with your remark. I moved on after two lines.

    Something is either pure or unpure. Ultra pure water is purer than pure water? Its like virginity, either you are or.... lets move on...

    Some non conductive liquids which may be used: alcohol, oils, petrol (?). But those are liquids, you might be interested in some gasses which may be used, check with your refridgerator repairman for those.

    Also, why would people want to run their comp in water? I think its pointless, but I'm sure it'll reduce noise to almost nothing :D

    A better thing would be to convert a small fridge into a computer chassis :D Plonk all your stuff into that fridge, maybe cut a couple of 5.25" bays from the door, and use silicon glue to seal the whole thing. Then maybe you can get your comp to run at subzero temps :D

    This may well be my 50th post (wahay) but anyway, wouldnt putting a computer in water increase the noise if water is denser than air and so sound travels faster...not entirely sure, wouldnt like to risk it myself.

    There are different levels of purity. Ultra means maximum in this case 100% Pure. Tap water is considered pure because it doesn’t contain any contaminants yet it is still not 100% H2O. Purity it highly dependent on the context it is used in.

    The fridge idea isn’t feasible, if you go out and buy a new fridge they recommend that you leave it running for a few hours before you place anything in it. They take too long to cool down, plus if you leave the cooling unit running beforehand and the case isn’t properly sealed condensation will build up on all the parts.

    Well, I read things literally. Pure means pure. no such thing as 95% pure. If any damned salesman tried to sell me something 95% pure and told me its pure, I'd sue the *** outta the guy. Tap water is far from pure, anyone telling you its pure is lying. No offense but I've never heard of anyone who needs something pure says something is pure enough (unless they're talking about 99.999% pure, such as gold).

    Same goes for hospitals and the sterility of their environment. If you ask a surgeon and he tells you the operating theathere is sterile enough, go to another hospital.

    And about the fridge thing, its not feasible. And so is alot of things people do to overclock their computers. I mean, anyone checked out the 5ghz project tomshardware came out with? If anyone says thats feasible, they're nuts (they used liquid nitro). Anyway, the silicon sealant is used to seal any holes, the only problem would be the startup time, you gotta run the fridge quite some time before running the comp, or it'll fry. Even then, gotta check the wattage of your fridge, too low and it'll still fry.

    Might work for me since I never switch off my comp.

    About the sound, sound travels faster in water than air, but it doesn't mean the sound is amplified. Go back to Physics, there's only that amount of energy there, if most of it got converted to kinetic energy (speed), the amplitude (loudness) isn't going to be that high. Also, you gotta change a couple of mediums, so energy will be lost there as well, making a computer running submerged in liquid pretty quiet. T

    yes you do have a point. But unless someone works in a lab, they probably don't have ultra pure water.

    5ghz project

    do you have a link to that 5ghz project?

    About the loudness thing...although it doesnt amplify it surely it would make it seem louder. I get what you mean about having a PC in water would be quiter...becuase unless you were in the water the sound still has to travel through air and would therefore be quieter. I dont think I was entirely wrong about the different densitys appearing louder though, as if you knock on a table it quite loud, but its a lot louder if you put your ear to the table. The point is I may not be that bad at physics after all :D just used the wrong words to describe it, shudve sed appeared louder instead of increase the noise.

    I really can't say anything about that myself, I'm really just using what I know on paper. Haven't really ubmerged a comp in liquid, and probably won't for a long long time. I'm scared to even use watercooling at this moment.

    A word on watercooling: I think its the best cooling solution ever! If only they'd invent something as good as water that doesn't conduct electricity. Everything I mentioned up there has a problem: alcohol can't absorb alot of heat, oils degrade in heat, and if they don't, they're pretty viscous, and petrol is pretty much an oil anyway.

    The CPU is the main heat producer (and lately the GPU is catching up) and whats better than whisking the heat away outside the casing and releasing it there, away from other components? Now they just gotta come up with waterooling for HDDs....

    One thing about this "ultra pure water", its easy to obtain outside labs. All you need is to run a pipe through a bucket of cold water, boil water and lead the steam into that pipe (with a funnel) and what comes out the other end is pure water. Make sure that pipe is clean inside, and the initial streams of water is probably unpure, so let that drain. After that, assuming you've cleaned that pipe (or tube I should say), you'd have 99% pure water. Depending on how you handle that water will determine how long it'll stay pure :D. Leave it in the air, and it'll go unpure pretty fast.

    One more thing people can do to prevent water from totally destroying computers will be to coat everything in a little grease. Tehre's some special grease available in electronic shops which can be spread over electronics to protect anything from a little water for awhile. should be long enough for you to detect the leak and start cleaning up procedures. Not really sure if its good for leaks, but its good enough for creating a barrier for ice (I was looking into peltiers if anyone had followed my posts).

    You can.

    I ran a computer that was fully submerged in water, or, at least, a composite of distilled water, 99% Isopropyl alcohol and antifreeze. The only component not submerged was the optical drive. The HDD was sealed to leave only the top cover visible, with the hole that says "DO NOT COVER" sealed. The HDD got hot but survived. The rest of the components worked quite well.

    It is very easy to get your hands on or even produce efficient non-conductive liquids. The only problem is maintenance. I don't fear a short at all - Because I'm not a fool.

    Most of the noise that one hears is from the fans in ones case. Remove case fans, chipset fans, motherboard fan, video and psu or anything else you have a fan on and your system is virtually silent except for optical and hard drive seek and writes. If you submerge your case or componants in a liquid the whole point is for the liquid to keep the componants cooler without the use of fans. Putting fans in the liquid would bog them down or if anything act as a propeller circulating the liquid wich in all would not be a bad idea but case fans or any kind of fan in your system does not have the power for that effect and would most likley burn out quickly.

    But thinking a little most liquids heat to there surroundings so one is still not seperated from having a radiator as with basic water cooling of any kind. Yes submersing your whole case in liquid without the use of a heat disipator would work far better than a standard water cooling system with a radiator that contains a fraction of the liquid, but if you never turn your pc off that liquid your case is sitting in is going to slowly heat up to the tempurture of your componants. It may take a day or I dont know how long but the temp of the liquid will rise to the temp of your componants. I could be wrong but it makes sense in my head.

    Just like in an air system or a water cooled system, you have to keep the hot "something", whether it be hot air or hot water, moving, to keep components cool. In a fully submerged system, the goal is often either to keep the liquid very cool via refridgeration, which requires a compressor and a radiator elsewhere to dissapate the heat, or a constant circulation of the water, keeping the fastest moving liquid nearest to the hottest parts.

    Heat does not travel through most liquids as well as it does through aluminum or copper, which is why you have to do these things.

    alright i wanna post this before i forget it. seperate the fridge into 2 parts. 1 small part for the computer (assuming it is completely and properly sealed of course) and a medium part for the food. then there is no need to turn off the fridge and its easier to clean and its less food you need to buy. or if your loaded just keep the fridge running 24/7

    actually your submersed system is commonly used on super computers...... I've never seen it on home systems though....

    Maybe this will be the dawn of a new error where well all have 'computer baths' on our desks and have to drop in cooler periodically to lower know, on the hand, buying a few more fans would be a lot simpler, maybe you could have an ice tray under a fan so the cool air would be sucked into the system...condensation may be an issue though. I am vaguely tempted to try this whole underwater pc thing an old pc I could use :D. Would the fan on the CPU's heatsink burn out though, as well as other fans such as the ones on graphics cards, could be fun though :D

    eh? is that sarcasim? if it is what is that supposed to mean! u turn off your fridge? god im confused. i quit. when i get it to work you can all be envious! MWAHAHHAHAHAHA!
