Mobo SUBMERGING project!

[PeTe777]

Hi everybody!

HEre is my plan:
I want to submerge the mobo into transformer oil and cool it with my chiller.Look at the picture(without oil) it is quite clear I think.Can you please provide me with your ideas and opinions (or even experiences?!) what to do?(or not to do..) Any links?
I think it should work better than my current setup with maze2 cause here is thermal transfer following: evaporator-coolant-maze2-cpu and in this submerging project it will be following: evaporator-heatsink(in the case of cpu) and evaporator-oil-memory(chipset) for remaining components.
Cooling capacity of my chiller is 280W at -15°C not sure if this is enough...

thanx in advance for your ideas!

here is the pic:

Hey Pete, welcome to the forums!

I'd like to make a suggestion...since many oils are hygroscopic (they can collect water from the air) I'd mount the motherboard vertically to avoid water sinking and pooling on the circuits. You could also slant the bottom of the tank to collect any water away from the circuits.

Looks like an ambitious project...great luck to ya!

How come everyone has cool graphics programs but me?!? Oh well I'm too lazy to learn them...

That looks interesting... A lot like another one I've seen today, perhaps you two should hook up...

i saw something like this on octools.com. they put a motherboard i a styrofoam cooler and put flurinert over it, and ran the flourinert through another cooler full of liquid nitrogen. the articles are under the supercooling link. mission submersable they called it.

 

[Starfoxer]

wow, i just read all of that stuff wonko. that is awesome.
imagine what someoen could do with a presnt processor.
a XP @ 3+ ghz maybe. man, they must have a lot of licenses
and money to get LN2 and the fluriscent (Spell)

really awesome

 

[Cuper]

WOW!!! I just want to know how you guys think this shiet up!!!!

Good Luck, Can't wait to see some pics of the bad boy!

Is that 3d Studio Max?

 

[Roger24]

Actually PeTe777 inspired me.
I took a quick look at the drawing and spontaneously, an idea formed in my head. I didn't even bother to read the text, I just loaded Paint as quick as I could
I have to give him some credit.

 

[PeTe777]

hi guys!

NuebieN - you`re right it`s 3DS MAX 4.2 really nice prog,easy to learn....

Roger24 what is your idea?give it here! I need any opinions cause were few people have done this with newer components...
I have seen some projects with 200MMX and so...nothing with athlons

any athor sugestions,I need some more info before starting this, like e.g. will this cool my cpu better like my current setup?

thanks...

where did you seen it? any link, thanks

hmmm, sounds very interesting, but probably less dangerous then watercooling (so it is not at all) i think you will have to use a computer heatsink, probably a sk6 - i have not seen a copper heatsink that large before, they are always aluminum.

 

[PeTe777]

hi overclocker,
actually I want to use custom made copper heatsink, as large as possible.

Don't worry... You aren't totaly alone. My best program is MS Paint...

As to the setup, I really like your idea! Just a few questions though...
1. Could you make the chiller tube go throught the HS in more than one place? It would be harder to put together (it would seem), but would also give better results IMO.

2. Have you thought about throwing RAMsinks on? I don't have any experience with them at all, but I definatly wouldn't want the memory to be a bottleneck with that kind of cooling system!!

XP @ 3000Mhz doesn't really work. It would create a "bubble" of hot liquid, which would be cooled too slowly to keep the processor from burning up. Transformer oil is NOT the best conductor of heat.

Try a quad 220w TEC block, with chillers and a water/methanol mix (chillers cooled by mains water to drain). That worked for me, at 2.895GHz. Didn't go to 3 though, waterblock slipped. So now I have over doubled the speed of a Duron

I never know how to respond to cool ideas like this.
Here goes:

To refine the idea you will have to do some serious
engineering. Since the hot spots are concentrated
to just a few points in the system, far better flow
needs to be directed to these areas. You have to
do the heat load calculations and scale your primary
cooling to this plus 10% or so. Then there is the issue
of upgrades. How do you do them w/o making a mess.
Speaking of mess, how about all the seals on the
system for power, drives, etc. At some point you
end up with a confined environment. This translates
to big bucks and a lot of time.

Given that we we know the limits of overclockability
or the current generation of CPUs, is this expense
and hassle something that is going to pay off?

You decide.

 

[PeTe777]

JigPu: It would be probably possible to do more passes with evaporator through the heatsink, for sure it will give better results...
And ramsinks are also good idea...

DarkInferno_IV: Maybe you`re right with that hot liquid bubble but if I can keep enough flow it should work. Now I`m moving
-15°C antifreeze/water liquid through the maze2 and I say you it IS dense-like oil....And when I don`t get this `bubble` in my maze2(flow is enough to move the heated coolant) it shouldn`t be prob cause now I must count that I use 1.8m of tubing which is also slowing the flow....and if you look at that picture you can notice that there will be very short tubing from the pump and pump will suck cool oil from the area where is only soundcard(as we know they are not producing any significant amount of heat) and blowing the cool oil directly on the cpu heatsink.

Tecumseh:1.how can I calculate total amount of heat from cpu(easy to do), gpu(don`t have any info),ram & northbridge?
2.upgrades-why you have always problems with mess?? I dont think that here is any prob.Ok so I will buy new graphic card-so I remove the old one and put there new one.Any problem?
3.I dindn`t understand what you mean with the seals...

And here is the ONLY reason why I would like to do this. I HATE all those stupid condensation problems, wrapping block, socket....with insulation..stupid work and if you leave some stupid 0.1mm hole somewhere you got it - direct cooling with water
I have done insulation work as good as possible on my old waterblock but when I removed it after two weeks of using it with my chiller there was water btw. cpu and block!!! Hehe but I completely insulated my cpu top(except the die ) with silicone so nothing happened to cpu but you have to see that aluminium block!!It looked really awfull, there was some grey-white-black stuff on it.....so I`m not woried about the cpu, but I don`t want to clean my waterblock every month...

Some may have stated this is smaller portions but I researched this kind of project a little while ago and here are my pointers...

1. The motherboard and cards should be sealed into a tank that doesn't have ANY outside exposure to air. As stated earlier, moisture in the air will start getting into the oil.
2. The cooling process would be much simpler if you had a pump and radiator outside of the motherboard reservoir. That way the condensation could be collected away from the electrical source.
3. You should consider mounting the motherboard upside down and vertically. The cold oil would be pumped directly onto the CPU and the "warm" oil would be sucked out of the top of the case. This setup would be much more thermodynamic

Well, that's all I really have to add. If possible the radiator and tank assemblies should be REALLY far appart from eachother. Maybe you could put the radiator over one of the air conditioning vent of you're house...

Good luck! You're much braver than me.

Here's a BUD (Butt Ugly Diagram) of my idea for a setup.

I WANNA SEE THAT!

and what cpu did you get the 2.895 at?
i hope your not tellin me that it was the duron in your sig.... cuz that would be crazy!

 

[Tecumseh]

PeTe777, a good guess for the total load of your rig
is the PSU rating. So 300 W if lightly loaded and 350 W if
decked out.

If your big beef is condensation consider two ideas.
In most home environments you can go 7C colder
than ambient before condensation can form.

The other idea: build a gas-tight cage around the PC.
Then pump is out with dry nitrogen and seal the whole
thing at slightly higher than ambient pressure. The
payoff here is that condensation cannot form if there
is no moisture in the chamber.

This second idea may be cheaper to build and maintain
than liquid submersion.

Just a thought....
