dustless pc?

i just recently upgraded my p4 rig to a core 2 with 8800. its blinding.
24 inch dell too.
im planning on watercooling and overclocking of course but ive always had an issue with fans for air cooling the main cavity in the case. everything gets covered with bloody dust. i hate it. no i mean i really bloody despise it!
£1300 on hardware the last thing i want is a fine layer of stability zapping dust all over it.
some might say what about filters well yes thats what im on at the mo but they still let dust in and decrease essencial air flow. at the same time noise is an issue and with filters it means more speed to keep the same airflow and so more noise.

sorry im getting to the point.

a sealed air cooled chamber is possible in my thinkings. completely dust free and maintained at room temps ( or below if interested).
my prototype will be made when i recover from spending 1300 bucks.
it consists of a 120mm fan and heatsink attatched to a cpu waterblock with a tec (watt i dont know yet some caculations required first) onto a standard 2 fan 120mm radiator cooling loop.
all set up so the heatsink and fan are the cooler side of the tec.
at this stage im guessing some might have givin up reading this and some might be saying too much heat in a case for one tec to remove. well im gonna be watercooling all my hardware.
cpu, northbridge, ram and gpu.
all thats left is harddrives and residual system heat. easy job for a tec.
the hard part i figure is controlling the tec and heat so i found the mcube t balancer thing and it looks up for the job.
it can be programmed in all sorts of manners and heres what im thinking.

with everything installed the mcube will be measuring the ambient room temps and the internal temps and doing its best to keep them matched by moderating the voltage of the tec. im guessing room temps would be best for condensation issues but if it can be kept lower then thats just plain sweet.
i have no experience with tecs so what im hoping is someone with more experience verify my concepts.

allot of work i hear some say but remember....
i really can not stand that blooming dust.

if you have an opinion i want to hear it...

yup but what about my 3 harddrives?
dont want them failing on me.

complicated but the idea holds water no?

Eh, HDDs really don't run that hot, if temps do get outta hand just get a passive HDD cooler, or add them to the WC loop.

What about the psu? Without proper cooling the thing will die. And the fans in a psu always act as exhaust. Unless the pc is completly air tight, the vacuum created from the psu fans pushing air out of the case will cause air to get sucked in through every crack. A single TEC isnt going to be able to properly cool a psu unless it's in contact with the heatsinks in the unit itself.

the psu just needs turned around to suck from the outside and blow outside.

and just to answer the hard drive thing. if i add them to the cooling loop for cpu and gpu cooling it will comprimise my overclocking levels. a seperate loop would be needed as im sure they do create enough heat to realy require active cooling for stability. so instead of cooling them and still needing fans and enduring dust cool them my way and remove dust. no?

psu arrangment would need a hole mod in the case but ive got the tools and know how so its not an issue. as is any case modding as i worked with sheet steel for 2 years.

thats my thoughts exactly mpilchfamily.
completely sealed.
psu seperate from the chamber.
im gonna have to post some detailed drawings i think.
maybe tonight after work.

yeah my flatmate has the antec p180 case and its great for the hdd and psu chamber.
right i think some have missed my initial idea.
ok so the idea of a completely sealed chamber has drawbacks like cooling everything that isnt cooled by watercooling. such as vrms southbridge etc. but the tecs cold side would be on a fan and heatsink circulating air in the sealed chamber( p180 is a perfect case for this). the heat the tec collects would then be removed by a watercooling loop. what size and properties im not sure yet.
now a tec set up like this is capable of keeping that sealed chamber alot cooler than ambient room temps. portable fridges tht run on 12v dc use this technology and they can be pretty damn cold.
alot of work to complete and considerably more technical than filters and low speed fans but how many people can say they have a true air conditioned dust free case for all their fantastic hardware?

ill try not to go off topic, but as someone mentioned earlier, motherboard components need some form of cooling, wether it be a light breeze or a watercooling loop. I dont think its possible to do what you want to do without having some means of transferring heat... now ideally. there is a way to do this. seal off your HDD and psu and cool them independantly.. then make your main chamber completley water tight.. fill everything with oil, have your watercooling rig set up to each main component. you'll have to work out the best way to do this..

right then in my lovely diagram, the blue area would be a sealed unit filled with baby oil (or any other suitable oil) (its non conductive and fairly good at heat dissapation) as far as im aware your pump could be in this bit. Your rad and reservoir would be located outside. you would have to work out how to seal the box around the tubing. you could then have a waterblock mounted into the sealed off unit (trying my hardest not to lose you here) and have your loop conect to this to remove some heat from the oil.

OR you could buy some compressed air and clean it every month

u missed the main concept i proposed there gow87.
the tec is the heat mover working with a watercooling loop.

If dust is a problem for you then there is probably lots of dust in the air in the room. Try getting the ducts cleaned professionally and/or purchase an air filter, HEPA filters work wonders when it comes to removing all particles from the air, but they're expensive. Try dusting the room more often and make sure to wipe all the dust away with a damp cloth instead of just kicking it up with "normal" dusters. If your computer is on carpet, either move it onto a desk, excessively vacuum the carpet, or replace the carpet with wood or vinyl flooring.

Other than that, the rest of the posts seem to help a bit.

yea i understand that much, but the problem i forsee is as someone mentioned earlier, its not just graphics and CPU and northbridge that need cooling. When you have even a minimal amount of airflow, you have air moving over your entire motherboard. If you have no fans at all, the ram, the HDD's, Capacitors everything thats on or plugged into the motherboard with some current running through it is going to heat up. yes the main components would be cool, but surely everything else would be unstable?

I work in a class 1000 clean room area and still get dust in a PC that the PSU and HSF fans had locked up (hey, with ambient temps at 68deg F and it only being a Pentium MMX233 it's holding up well), admittedly it wasn't enough to clog the old style HSF but there was dust.

The only way I can see for you to have a "dustless" PC is to immerse the mobo in a flouro-fluid (or some other kind of nonconducting fluid), dust particles are attracted to the PC partially because of the static field generated by the electronics so the only way to avoid that is to have a barrier that stops the dust particles.

Perhaps someone will be so kind as to softly flame the following possibility, or tweak it until it works:

1. Mod the case to duct air to the input of the PSU. Mounting the PSU upside-down might help. Use gaskets or otherwise seal this duct as much as possible.

2. Seal every other opening in the case. Tape, plastic, or even Great Stuff could be used, with weatherstripping on the seams.

3. Bolt a Peltier unit to the outside of the case, and a large, low-speed CPU fan on the inside opposite the Peltier unit. This fan plus your regular CPU fan should circulate air within the case.

The air seal is not likely to be perfect, and condensation might be a concern. You will still need to blow dust out of your PSU from time to time. Otherwise, assuming you don't have a massive heat-generating OC, I would think this would work, and be reasonably quiet.

So, would it?

ok im glad ive got some heads together.
in my idea there is a fan inside the chamber moving the air around(tecs coolside heatsink fan) and there will be some other fans strategicaly placed for the components that arent cooled by a seperate water cooling loop.
the cd drives are already air tight in my case. it was just a job taping up the gaps between case of the drive and pc case. but thats all hiden behind my facia so its neat.
my whole case is taped up tight only letting air through two 120 filters both with fans running at med speeds. one extraction, not filtered, running at slow speeds.
with a sealed chamber i plan to sound insulate the whole thing so its dead silent leaving me with only the radiator fans to contend with and ive got some plans for those too. but thats another post.
this is getting built by the way.
