Aquarium Full of Oil For PC Cooling
JaredOfEuropa writes "Forget fancy watercooled CPUs or complicated heat pipes. Annoyed with the noise of the forced-air cooling in his computer, this guy simply dumped his entire motherboard in an aquarium filled with mineral oil. (coral cache). No modifications were necessary; he even left the fans running to keep the oil moving about. The only thing not submersed in oil is the hard disk."
Original site here.
I'm surprised that the PSU and all the cables (like speaker/CAT5) work at all, I feel so uneducated.
And I guess his parts have very little resale value?
Rock that crushes, Paper & Scissors that don't matter.
So if this thing overheats, does it deep fry itself?
Can someone please explain why this works? Why doesn't submerging it in oil just destroy all the parts on the motherboard?
Can we do the same thing with water instead? ;
he only thing not submersed in oil is the hard disk.

And what about the CDROM drive eh, eh?!

Mineral oil?!? I'll bet all his fish are dead!
I've abandoned my search for truth; now I'm just looking for some useful delusions.
From the looks of things, maybe his server could use some cooling. :-) Looks like I might have the first post, and the link posted above is already gone.
I'm very responsible, when ever something goes wrong they always say I'm responsible.
This has been done before, as reported by slashdot almost six years ago. Of course, the guy in the '99 story used a styrofoam cooler, while the newer one upgraded to an aquarium, so I guess progress marches on!
I'll keep the convenience of clean messing inside my current, completely quiet, oil-free PC, anyday.

Very interesting system. Would this work for all electronics, not just computers? This was on digg last week.
I herd about somebody doing this with a old celeron 300mhz? Stuck it in a cooler, and overclocked it. I don't recall how fast he got it, but it was crazy.
I don't see any fans or other way the heat is dissipated into the air, from the oil.
I guess he uses it for an hour, then the oil becomes the same temp as the cpu.. and then shuts it off? Since he says that the forum isn't in english, I didn't bother to check.
However, nothing is visible in his pics...
I'd say that the only reason this hasn't gone *boom*, is because it looks like a PII or Celeron (Slot 1 card).. and he hasn't really pushed it for long periods of time.
After all, it's immersed in mineral oil, which makes one wonder ... at what temp will it catch on fire? A good slashdot effect and whoops, there go the sprinklers ...
And what if his cat gets thirsty? Will it suffer any ill effects?

I saw a few years ago (probably here on /.) where someone put a MB into a tank filled with glycerin, then put an air conditioner cooler grid into the tank with it. A pump curculated the glycerin over the cooling grid and around the MB. I thought that was pretty extreme. I guess the main point is that you don't want something corrosive or conductive, and you do want something with a sufficiently high specific heat to take the heat away without cooking the board.
There is nothing so silly as other peoples traditions, and nothing so sacred as our own.
I'm an elevator Engineer. This reminds me of a very old residential elevator controller I saw recently that was installed in 1917 and still had all the original equipment in good working order. The controller was in a cast iron tub with all the relays mounted to the lid and suspended in transformer oil. There was a hoist in the ceiling to enable lifting the lid for access to the relays. It would cost a fortune to build something like that today, but it certainly was durable.

I wish I'd thought of that! Tired of the stupid computer that makes so much damn noise? Dump it in the fish tank full of mineral oil! (we won't go into why the fish tank was full of mineral oil). Well, hell, we've been drinking... I wonder if it still works... Whoa, it does work! Neat - take some pictures!

At least I'm assuming it is. How many times has this subject come up?
Maybe we should hold competitions to see who can make the best mineral oil cooled machine?
I'm tempted to make a dry-ice cooled block (dehumidified of course and allowing for temperature gradients...)

I don't see anything that he has done to cool the oil it would seem that he has decreased his surface area for air cooling, It just seems to work off the thermal mass of the oil.
This would work great until the oil reached a temperature similar to the max temp for the CPU.
Now if he added a little fountain or a bubbler, or something, that would increase the surface area and thus increase the cooling.
Now if he added little neon lights, some racing stripes, and some anime stickers, we could get some of the less infromed case modders to make some great messes in their cars

The guy uses vegetable oil not mineral oil according to his site.
I did this for a year or so using mineral oil, a plastic storage tub and a small dorm-sized fridge. I had a small electric pump that pumped mineral oil into tubing which was coiled inside the fridge (drilled and in and out hole on the side) and then back into the resevoir. I was a little worried about condensation but it ran fine for over a year before I got tired of the clutter and mess of it. I could have done it better but I didn't want to spend any money on it and just use what I had laying around.
It was mostly for fun with a few interesting things I learned from it:
* It allowed me to overclock about 30% more than I could previously squeeze out.
* The mineral oil did not harm the hardware at all that I can tell from a year of being submerged(it just was a pain to clean).
* If you have your resevoir higher than your mouse then your mouse will be full of oil in a few weeks (same goes for any component connected by wire I imagine).
* The only component I found that could not be submerged was a hard drive.
* The outside coating on the wires will harden and break away after being submerged long enough(but they will still work).
* There was no connection issues with PCI cards or any peripheral device that was plugged in even if they were coated in mineral oil(even jumpers could be changed while it was submerged).
* If a drop of some other liquid (that is lighter than the oil) accidently falls into the resevoir it will quickly be coated by the mineral oil and slowly fall to the bottom and can be sucked out (phew!)
Probably more but those were the most interesting things I remember of it.
Of course, none of that really matters, since the images are on a different server that neither Coral nor the original site are able to access.

Flash point: 135C (275F) CC If any one component or combination hits this it will light on fire. P4's can easily hit 100C even without overclocking in some systems (limited cooling). If there is not enought oil to air heat exchange occurring, it could catch on fire if he keeps it on too long...

So he immersed everything but the hard disks. Makes sense for many of the parts, though I'd be a bit concerned about oil interfering with cable connectors, but immersing the speakers just sounds likely to fail :-)

So oil conducts heat much better than air. So the heat is going to be conducted away.. where? Hmm.. the aquarium walls. Then where does it go? Into the surrounding air. At a rate determined by the amount of surface area (and the airflow).
Thing is, I wager the aquarium walls have a lower total area against the surrounding air than his computer would've had otherwise. Which would mean that he's actually getting rid of less heat, and that in the long run (e.g. when the abient temperature, oil temp and computer temp have reached equillibrium) his computer is going to be a lot warmer than it was.
Or?
(And I can imagine that oil doing quite nasty things to the polymers in the machine. But that's a different story)
Did anyone notice that the images aren't on a coral cache server? They're hosted on the same server as the images for the original site so it will still be slashdotted. OTOH, mirrordot cached the images properly: http://www.mirrordot.org/stories/7bb0bea011df80856 9857f1175b25bee/index.html

Since oil is electrically inert, how is he going to use any of the expansion slots on the motherboard should be decide to remove it from the oil?
I would imagine that even a thin film of oil on the electrical contacts will totally (to use the technical term) bugger it.

he even left the fans running to keep the oil moving about. A bad move: his fans will soon burn out because they weren't meant to circulate oil, but air. With fans gone and the oil stagnant some parts of his computer will start to heat up...

I wouldn't worry. The mineral oil will kill the cat long before the level drops far enough to have any ill effects on the mobo. Now, if the cat dies and falls into the aquarium, there might be a problem.

So... how about adding some colored wax and putting all the components at the bottom of a tall/hexagonal aquarium and making a PC that IS a LavaLamp?
Not sure if the heat would get high enough to provide the necessary melting of the wax or fluid current in the oil, but as I recall, it doesn't require too much heat... my circa-1976 official LavaLamp only used a 30-watt appliance bulb.

This makes me wonder: since oil and water are immiscible, wouldn't it be possible to put some mounting brackets in the tank for all of the electronics about halfway up the tank, then fill the tank to below that level with water, little plastic castles, and fish, and then with oil to the top?
Aeration might be a bit of a problem, but one could put a divider in the tank and have the bubbler on one side and the electronics on the other in case the bubbling action caused mixing between the oil and the water. If it was designed properly, it wouldn't even be necessary to have oil on both sides of the divider, just on the side with the electronics, although this would definitely make changing the water a delicate process.

If he put some sort of radiator (heat sink?) on the top, would that help him any? As the warm oil dispates its heat through the radiator, convection would cycle the oil in the tank.

Yah- I remember an experimental F-5 radar that emitted 40Kilo Watts (take that, Pentiummmm!). It was about the cubic of a full tower ATX case. Aluminum case, machined heat sinks on the inside, the outside was mounted to a cold plate that was chilled with turbine bleed air. The R/T was mounted inside the case in a three dimensional kind of array of solid state and passive components. Fluorinert filled the cavity. Screwed the lid on, and it went to work. Heat flowed pretty well (thermal sensors built in to the circuitry at various spots) so straight convection was used (no fan, etc.). Worked great !
Seems to me that while the fans would be plenty capable of running in air, pushing around something the density of oil would put a lot of extra strain on them and cause burn-out?
Of course, you could always put a more resiliant fan on the case, and one of the advantages I could see is that they would definately be well lubricated (if if the oil stays clean, they'll not seize from dirt/etc for a long time, more likely to burn out).
Some things I would do if attempting a similar project:
a) Fans intended for moving liquid.
b) Protective covers on the PCI, etc ports so that later cards can be added
c) Seal/Cover up the other plug holes such as USB etc for later use
d) Perhaps something snazzy like intake tubes etc with fans on the end to move stuff around. Perhaps different coloured inert fluids (with high boiling points) for a cool effect when the fluids move around).
More efficient way is not to submerge the whole computer in oil, but just parts like psu. I know in a latvian forum a guy made a custom psu box and filled it with mineral oil for cooling...combine it with a self-made water cooling and the answer you get is a completely fanless computer. Now, try upgrading or changing a part in a computer that is floating in oil...
I'm building a case/cooling mod right now using liquid nitrogen!
Assuming you meant water, the you're wrong. Just water is quite a good insulator.
The US Navy was using water cooled computers long ago. Just flooded all the circuit cards with distilled water.
Note that you have to do this with pure water. If you dissolve much of anything in it, then the SOLUTION begins to conduct.
Most of the water you come into daily contact with (puddles, rivers, flooded basements, even tap water) has quite a bit dissovled into it, which is why generally electricity and "water" don't mix.

Why can't the hard drive be submerged? Does the oil leak into the casing?
I'm surprised that the PSU and all the cables (like speaker/CAT5) work at all, I feel so uneducated.
Actually, I'd be more worried about the high-speed circuits in the machine. Oil does not conduct electricity, but that doesn't mean its electronically equivalent to air.
Oil has a dielectric constant of between 2 and 3 (depends on the oil) and that will affect the capacitance on and between the traces of the circuit-board. The signals will run a little slower on the board and have a bit more cross-talk. Its probably not a big deal -- the materials in the circuit board have a bigger effect -- but it could slow the signals enough to reduce reliability in a marginal design.
Two wrongs don't make a right, but three lefts do.
I have a WD 120gig and it sounds like an A-10 Warthog pulling out of a dive after straffing a Taliban T-72...
God I hate WD drives... OTOH, I installed a new Maxtor 250g for a friend and it was so quiet I had to pick the drive up and feel it gyro in my hand to be able to tell it was running.
I don't mind fans so much but the whine of hard drives is pretty unbearable, especially when you have 7 pc's running at the same time.
But it would be nice if they could work on quieting everything down. It's a noisy world we live in. Too noisy.
At one time I worked for an electric utility and it was a definite consideration there in dealing with the old transformers. So no, I didn't get into the oil. I'm not a union employee anyway and can't mess with the hardware or I'd get in big trouble. I can design it, oversee installations, oversee troubleshooting and program the controllers (in assembly language), but can't pick up a screwdriver on a job site. This old oil is a problem the owner will have to deal with at some point. It's really interesting to see some of the old well-built gear that still works well as long as it's maintained.

One of my friend approached me with this Idea back in 2000 and it's was so grotesque, that I designed an entire silent computer based on thermal Conduction.
The design can handle over 300 watts 3.X P4 cpu at full load, + drive + graphics cards and operate at near room temperature.
Just aluminum, drive is in 1" thick thermally conductive Silicon Rubber. (I added stuff to make it conduct heat)
Mineral Oil is just a bad idea. Even in my Aluminum design I have so much criticism about how hard is it to work on, get the parts etc. It's actually easier, but people just can't handle different then the status Quo.

If it wasn't for the fact that once anything is in that water for any ammount of time it'll both start to corode the metallic contacts as well as become electrically conductive.
That's why he used mineral oil. It's electrically neutral, and doesn't corrode metallic components.
but does it run? :P
*ducks*
Like you said, the idea is not new at all. I remember seeing this years ago, the whole thing was submerged in a clear plexiglass container (much like an aquarium, but lower profile and trays over it for drives).
;)
And generally speaking mineral oil isn't really a good coolant (not very effective at heat transfer), and it's very messy (imagine taking out parts... no thanks!). And you'd think there would be some decent cooling for the oil... I'd like to see the oil temp grahps given a decent load, it just might eventually fry

Some of the earliest hard drives were filled with oil - at slow speeds it kept the heads flying.
"Win treats sysadmins better than users. Mac treats users better than sysadmins. Linux treats everyone like sysadmins."
Objects with larger surface areas can be placed within objects of smaller surface areas.
Imagine an object consisting of lots of parallel plates, placed together with gaps on a base. Imagine decreasing the gap spacing and adding more plates. You can decrease the gap spacing more and more, add more plates, and the surface area will keep increasing. The surface area will soon become larger than a surrounding cube.
I bought a jug of fuser oil on ebay for $6 and after filling the fuser tank I started using the rest of it around the house. Great stuff!
Slick as hell, doesn't seize up like motor oil.
I have a lot of various fans around the house that I have to oil frequently. I have been using motor oil but it gums up after a while and the motors seize up. So I cleaned them all up and used the silicon oil on them. Man, it doesn't get any smoother than that. Not one seizure yet.
And, it does NOT break down plastic and rubber like other types of oil does so it's safe to use on just about anything. And as far as I know, it's non conductive and non-flamable. I just don't know about the cooling properties of it. Though I can't imagine that it would be any worse than the cooking oil or mineral oils, which BOTH are flamable and both will break down plastics and rubber..
And it's cheap enough...
The hard drives are the real noise makers on my computer. Especially since there are 4 of them.
One question. How did you clean the components afterwards? I assume you didn't just throw everything away and reused some of the parts. Didn't the unused expansion slots on the M/B and the open USB, serial, etc. ports have oil lodge inside of them?
just wondering if he has to change out the oil a lot
No, they aren't sealed. They do have a lot of filtering between them and the surrounding air, but they aren't sealed.
I don't think I'd want to buy any secondhand parts off of this guy.
...for someone to figure out how to do a "lava lamp" effect with this, mount their hardware in a rack that's inside a large clear acrylic tube like those used for fancy aquariums, and watch all the pretty backlit blobs moving this way and that. That would be cool.
If my grammar and spelling are off, I am [distracted/tired/careless] (take your pick)
Stickiest dust bunnies EVER.
And you could add 2 giant fans to blow air across the fins to keep it even cooler!
That is actually a good idea that really would make cooling more efficient. Larger fans can move as much or more volumes of air at slower RPMs than smaller fans. Lower RPMs means less wear on bearings and quieter operation.
IIRC that is the strategy used in the new BTX form factor cases--the heat sync on the CPU is really big with a lot of fins and a big fan that draws air through those fins and over the motherboard (to cool the chipset). Current ATX setups are most often laid out poorly for cooling, and you end up seeing high-end systems with 3 or more fans in the case. It is the need for multiple small fans that makes these PCs noisy, not the fact that they require fans at all.
I still think it would be great to see the return of the days when chips and power supplies ran cool enough to allow for practical convection cooling. My fanless Atari ST was blissfully quiet--even the comparable IBM ATs of the day that only had a single fan in the power supply were horribly loud next to it.
Now we should dump SCO in there so that they can dive down and see if he's running unlicensed Linux.

As this is really a re-hash of an old story, I'd be more interested in what happens to these rigs over the long haul. How long does the computer last in oil? How often does he have to change the oil? How does he cool the oil? How long before the mobo and cards are somehow affected by the oil?

So what about the connections in the PCI slots and such? Can't mineral oil get between the card and slot's contacts?
Do you have to keep the cards perfectly still to keep a strong contact?
Can you swap cards in the tank?
Can you adjust a connection (USB) while the machine is on?
I looked in the forums and nobody mentions this in english. Just stuff like "bloody brilliant"..

I'm pretty sure they aren't completely sealed, and submerging them in oil can have negative effect on electrolyte (and therefore on all components that these capacitors filter the power for).

When it said coral cache, my first thought was: "He didn't remove the ornaments from the aquarium?"
Read my blog: HansMast.com
is that every last connection has to be SOLDERED DOWN in order for this thing to work for more than half an hour.
The problem the guy ran into six years ago was that the mineral oil seeped in between all of the connections and disrupted the flow of electrons; PCI cards, AGP card, CPU, IDE, power... everything. A stock motherboard simply won't cut it, you have to have a custom board with everything hard-wired to it to survive the submersion.
This story is a dupe because it doesn't solve the basic problem.

You're using her as bait, Master!
I thought hard drives were completely sealed so why does it matter if it under the oil.
I am considering doing something like this with (Dow 561) transformer silicone oil to protect electronics left in the field here in humid Florida. I suspect that in the long run this may or may not produce problems because the oil is inert for most things but not compatible with PVC for example. See section 3.10.1 in http://www.dowcorning.com/content/publishedlit/10- 453-97.pdf?DCAPP=&DCWS=Power%20and%20Utilities&DCW SS=Fire-safe%20Transformer%20Fluid
Some plastics may not be compatible with mineral oil either after months or years.
I bought the 561 in bulk, but anyone wanting to experiment with a small amount of silicone oil can buy the DOT5 type of brake fluid at an autostore (it is mostly silicone oil).
On a separate note, I have been meaning to look into the radiowave absorbing properties of silicone oil - if it is high enough a cheap plastic case could be used instead of metal (heat dissipation would be less but that would not be a problem for me). I'll try to follow up with a comment if/when I find out.
The only component I found that could not be submerged was a hard drive.
Where you able to submerge the CD ROM drive? Wouldn't that negatively effect the play speed?

Hope it never gets hot enough to boil. (If the guy's runing a Pentium 4 it just might.)
MSBPodcast.com The opinions expressed here are my own. If you don't like 'em... Think up your own stuff.
i'm not too sure when i saw this, but it was probably 8 years ago. there was a guy known online as Dr. Freeze and he had a site filled with pics of his submersion. He had bought like 3 bottles of mineral oil and submerged his motherboard and etc inside a styrofoam box. He also had a air pump. Later on in the pictures, he took apart his a/c and turned it on flew blast.
I used to have the pictures, but it's been too long and probably lost during one of my hdd crashes. if you google "dr freeeze" and "minieral oil", you can see people talking about him.

How do you dispose of the oil? You can't just pour it down the sink...What are the consequences of everyone having a few dozen gallons of oil for home electronics that become obsolete in an average of 2 years?
This is new news? It's been done before. Move on there is nothing to see here.
First thing I thought of was hmmmmmm I want Fish in there.
Imagine a standard aquarium with the PC occupying the bottom third of the tank. Fill the bottom third with mineral oil.
Fill the top two thirds with Water and put in fish. Assuming we keep surface area of the glass is enough to keep the heat in control, the fish could live a long happy life.
I may experiment with this.......oil and water don't mix - so the fish should be fine - right?
Dupe or not, I still like the concept.

..so why was it not accepted then? I found this story from here
Proof: If, under normal circumstances, a computer will work for, say, twenty years before the motherboard stops working, and a hard drive will work for, say, five years, then by using the setup I described, you will be able to accomplish the same in the time it takes to plug it in and turn it on for the first time.
Efficiency is, after all, the wave of the future.
No, it's not mineral oil he's submerged his computer in, it is in fact vegetable oil! Had you accepted my submission, oh CmdrTaco, this little typo would never have crept in....
Of course, while a Mac will run cooler, it won't look nearly as cool as a motherboard in a vat of oil...
Sheeesh...
You are absolutely right.
That case is much better than this fish tank! Love the lighting too.

ffs this is old as hell i seen this on pretty much every other tech news site over the last few weeks.

Not all mineral oils are clear, and mineral oils are certainly used in electrical equipment. Dielectric oil, used for insulation and arc-extinguishing in power distribution equipment like circuit breakers or power factor correction capacitors, usually has a nice yellow tint to it straight from the manufacturer.
Best part is, you can usually get 55-gallon drums of the stuff from a local rural power co-op. (The stuff makes great diesel fuel once you filter out the carbon -- I used to use it in a Reddy-Heater to keep my workshop warm in the winter.) Just make sure the used oil is PCB-free, which it should be since companies that handle used oil are generally required to submit extensive paperwork on PCB-contaminated oil to verify that it's disposed of properly.
I was at the "Icon Byte Bar and Grill" in the SOMA area of San Francisco. They had a few televisions with the covers removed and completely submerged in mineral oil filled fish tanks of different shapes and sizes.
I also think this was one of the very first internet cafes, as I had never seen one before and the web was crap.. I remember thinking as I browsed with NCSA Mosaic, "what's the point? I'll just use gopher, it does the same thing."

Actually the link is now long dead, but someone did this in 2001, and did it in an even more haphazard and impressive manner!
Same deal, but in a Strofoam box, with Mineral Oil and an Eheim pump moving the oil from the reservoir where the mobo and proc were situated and over the bare compressor coils of a stripped 1000btu Air conditioning unit resting on top of the whole setup.
This has been done before, more than once. The first time I read about it was long enough ago that I don't remember when it was..
Wouldn't the fish be crumbed or battered?

Fluorinert FC-77 /. that cost at least as much as 2 liters of this. I wouldn't be surprised if someone was already doing it.
5 ml - $28.16
25 ml - $89.25
100 ml - $257.38
250 ml - $561.74

There have been cooling systems on
I can vaguely remember this being on Slashdot before. Though then it was iirc a AMD 5x86 on 160MHz or so.
"is that pure water is a goog insulator."
Now we know how to stop eggs shorting out when you boil them.
I believe it's more commonly used in the UK than the U.S.

Hm.............
Maybe we have different ideas of "better".
These guys used sunflower oil, and a container, and it works.
A pump is overkill, and a styrofoam container is against the purpose of losing heat.
What would be just a tad cooler is a chromed or white tin container for the oil, or even an oil can, and some rubber "feet" or isolators for the
components.

Nothing is submersed. It is either submerged or not.

I used to, but it gets too sticky and the girlfriend says it smells.

well, given the regularity of dupes around here, I'll go out on a limb and say as dupes go, this one is at least new to most of us.
Oh, well...I do that in place of having a girlfriend. I find the chemicals complain far less than the women-folk do.
