Pressurised Cases

[UnseenMenace]

I was wondering if anybody has actually sealed a case completely so that there are no air leaks. Then pressurised the case, or created a vacumn in it, and what was the out come

[Phil]

it would overheat and break :)
You need a medium to conduct heat to or else it would just overheat. This is no doubt gonna start a debate, just like the one about a computer in space where it's like -200°C etc.. but theres no medium to conduct heat to. Maybe if you watercooled everything then it would work but what would be the point?

Ok perhaps I need to clarifiy things and confess .... would the situation change if air was constantly removed from the case, and all other gaps were sealed?.. Im just curious as In a moment of bordom I sealed up all the gaps of my old P200 box with epoxy (I even sealed the CD and Floppy drives.. hehe) and the only way it can get air or loose it is through the Dyson that is connected to it.. By changing its direction I can add pressure to the case or create a slight vacumn. Ive not run it for a long time yet though, im gonna play tommorow and was just wondering what you all thought the out come would be.. temprature wise not performance wise (I cant open the box to tweak it)

Even then, watercooling requires maintenance. So you would have to open up the vacuum'ed PC and check it and the possibility of replacing parts, etc. Then you would have to re-create the vacuum seal again. Too much hassle, even for someone like me.

I still don't get why you need to do it. I know some people are festidious about passive cooling and seal up every gap so that the only source of air is the fans, but this is just to avoid pressure problems as low pressure can suck dust in and high pressure can make annoying noises with fans changing speed and so on.

I did it from boredom and curiousity, no other reason, the PC is going in the skip this week, unless of course anyone wants a sealed P200.. lol

Does it work? what specs is it?

[UnseenMenace]

its a P200, 32mb or ram, ISA soundblaster compatible clone, matrox graphic card (think its a G100 dont know what its got on board).. but yes it does work (no idea what mobo though)

[Phil]

I'll have it if your giving it away :)

that would be an interesting concept to even try, taking all of the air out case and making it a vacum just to see how long everything would run b4 it starts to overheat. and takes temps on everything in the case.

i doubt it will work, the will be no way fo the heat to travel except throught rays, paint the inside of the case in black, it might help heat transfer

[Random Nonsense]

ok vacuum = bad idea
pressure = good idea

denser air can conduct heat away more effectively, but you still need somewhere for the air to get out. get a big compressor, and attach the hose to the case, SEAL EVERYTHING REALLY WELL! and isolate the cd drive etc from the pressurised part as it will blow the doors out!

ones slight problem though, for the pressure to be high enough to affect cooling, the amount of energy put into the air to pressurise it will have heated it up. Still might be interesting to try it.

i have had crazier idea's :p

[The Overclocker]

why dont you just fill the case with water, or even better, mercuary

[Flash]

It's generally a good idea to force the air to flow in/out through your fans. It maximizes amount of fresh air flowing past your cpu (assuming your airflow is properly designed).

[UnseenMenace]

Ok did the test and nothing really happened, I got so much pressure in the case that it eventually kinked and forced the CD-Drive open for some reason. So much for boredom.. hehe

[fuzzba11]

If you filled a case with completely purified water with no additives it should still work...remember that it's only particles in water that makes it conductive. Somebody should try this with an aquarium...submerge a Pentium or some other practically worthless system in boiled, purified water...might just work!

AGH THE P200 HAS CREATED A BLACK HOLE!
