Interesting Idea for further cooling water.

So guys....I've got this fridge lying around and an idea occured to me......

Just kidding....

I came up with an interesting idea for a fanless watercooling system but I honestly have no idea how it will work....

What you do is basically have two loops. One is a standard watercooling loop inside of a computer, the other comes into play at the radiator of the first loop. What were to happen of you were to design an oil based loop resevoir around the radiator and disperse it using a pump to another radiator (or bong cooler possibly?) to dissipate the heat.

If my understanding of a bong cooler is correct, since the oil wouldn't evaporate as easily as water, it might be a little more effective.

I understand you still have the same amount of enegery to dissipate out of the computer from the first loop as well as the added heat from the 2nd pump but in all honesty, wouldn't this work a little better?

1.) the compressors in a frig/freezer aren't powerful enough to cool a computer, as refrigerators/freezers never have anything is them that actually produces heat.

2.) It's the evaporation of the water (latent heat of vaporization) that causes the cooling in a bong cooler. No evaporation = no cooling.

1) You missed the point where I said "Just kidding"

2) The bong cooler was just a suggestion. Would it be effective to use a 120 rad with oil and then cool the oil with a 480 or 360?

You're basically describing a liquid to liquid cooler, which is great, but you still need something to cool the liquid that cools the liquid that cools your computer parts.

Does that make sense?
yes, and as I said, you use a bigger rad to dissipate the heat on the oil. I'm just not sure how well you can get the heal away from the oil in time. before it recycles back into the system.
Mineral oil has a high specific heat capacity, so you'll have some time before the oil heats up to the temperature of the internal fluid. You're right that it would need cooling then, but how would you cool the oil? If you're just going to use a bigger radiator, why wouldn't you simply use that as your primary cooling system?
Oil cooling is useful for high-energy or heat temperature cooling... neither apply to PC.

Mineral oil has a lower Specific Heat Capacity than water. And since Specific Heat Capacity is a measure of how much heat it takes to cause a temperature rise (higher numbers means it takes more heat to cause a temperature rise), with the same energy added, mineral oil would heat up faster than the water. But that's a moot point since, in the OP's system, the mineral oil couldn't get hotter than the water anyway

Are you sure about that?

well im preaty dang sure of that, because there is one thing wrong with that post of yours. one being that the hp rating of residential phase units is commonly around 1/32 hp to 1/16hp, only exception is with extremely large chest freezers(10ft+) you might see a 1/8th hp compressor. i wouldn't recommend anything less then a 3/8th hp compressor for todays processors.

another reason being that the compressors used in fridges aren't designed to take on heat. sounds kinda stupid right? well actually when you think about it. beer doesn't product heat, so why would it need to be able to handle much heat when you have nothing in there that is producing heat?

I noticed alot of doubter's on this site you people need to be a little more open minded. but anyways here you go eat it up

Thermaltake's Xpressar RCS100 PC cooling system combines a computer case with a refrigerator.


Thermaltake has officially announced the Xpressar RCS100; the world's first DC-inverter-type micro-refrigeration cooling system for a PC. Essentially what Thermaltake has done is combine its Xaser VI computer case with the guts of a refrigerator, which is definitely a cool idea. Apparently, the Xpressar RCS100 was able to cool an Intel Core 2 Duo E8400, which had been overclocked to 4.05 GHz, down to 35-degrees Celsius. If the claims are true, that is 20-degrees cooler than the average water-cooling system. As well, with a single 120 mm fan running at 1600 RPM, the noise in the system is claimed to be a near inaudible 20 dB. Somehow it seems hard to believe that the system's condenser pump would also be that quiet however.

The Xpressar RCS100 is definitely designed with the overclocker in mind, although it does not go too lightly on the power requirements. With the micro-compressor alone using upwards of 50 W, Thermaltake recommends using a power-supply that can support the system hardware plus an additional 100 W. As for PC system compatibility, processors using Intel's LGA775 or LGA1366 sockets are supported, meaning this system should be compatible with Intel's upcoming Bloomfield processors. Many popular motherboards are supported, such as the Asus P5Q, although a motherboard with an odd placement for its processor socket may not be compatible. Lastly, some motherboards will leave only enough room for one video card, mainly affecting MSI motherboards it would seem.

The micro vapor-compression refrigeration system used in the Xpressar RCS100 is like that of what you might find in a refrigerator or an air-conditioning unit. The CPU cooling process involves a phase change of a refrigerant from a liquid to a gas state, which allows the refrigerant to absorb heat from the processor. Afterwards, the compressor and condenser work together to bring the gas back to a liquid state and the cycle begins again. The refrigerant is environmentally-friendly and the system is equipped with an intelligent IC controller to prevent condensation from forming.

There is no word on price yet, but it should be available at retail stores shortly.

It could be a turbo flex capacitor to the 9th degree, and if its made by Thermaltake, it would still be.....Thermaltake

It's the same concept as a fridge, just different parts. The pump is more durable than a regular fridge pump, which would die after about a week's worth of use.

see this thread: http://www.overclock.net/cooling-exp...ad-worked.html

He he put his pc in a fridge and got the exact results people predicted: not very good cooling, and it only lasted a week.

@ op, interesting idea, but one of the reasons that mineral oil is used to submerge rigs is because it's non conductive, not because of a higher heat capacity. And the bong stuff has already been said. It cools via evaporation.

I think you would be better off with either with a water bong, or some kind of active cooling. You can use a tec for sub zero cooling on the processor itself, or you could use a gutted window air conditioner along with a 50/50 mix of antifreeze to get your water temperature down to -40C.

I have just recently set up my new computer system fully water cooled, i am now designing a seperate sub tank where the extented water piping sits in (about 4 meters will be coiled in side the tank) the tank is then filled with an antifreeze that can stand temps of more then -70 then i will get a phase change unit and plug that on this tank that way the anti freeze in the tank will be kept at below zero temp and the piping for the computer components (seperate anti freeze) will also be kept at below zero temps this i think will keep all my componets at below zero NOT just my CPU as all Phase change units are just for cpu's.

the best thing is the GPUS will be LOW as hell wich means I will be able to OVER CLOCK if i knew how to haha.


does any one see flaws in this???

the one i see is the condensation on the pipes, does anyone know how i would combat that ????

you can run a fridge compressor just fine but you'd have to run it hot on a pressure sensor so that you dont blow your compressor in a month or so.

forget about heat capacity of oil. what's going to give you nightmares is pumping it. unless you are willing to run an oil pump (very very very loud), it's not the heat capacity of oil that will stop you. i speak from experience on this one.
Why not create your PC loop normaly and place the radiator in an open resevoir of water. Then modify a fridge to have a hole in it that you can tube to the open resevoir. In the fridge you could have a separte resevoir of water that the fridge would keep chilled and create a slow trickle to the open air resevoir. That should prevent the heat from returning to the water in the fridge and keep the bong cooler filled at the same time, though you would have to refill the fridge. Don't know if a trickle or a timed release mechanism would work better though.
