Have a Resovior??? Read this

Tuff · 04-02-2003, 01:31 PM

Those of you with resoviors might be interested in this...I have seen a discussion on here reguarding evaporation cooling. Most being about large or bulky contraptions (I do not mean any disrespect to anyone I appreciate all that everyone attempts).

Anyhow...There would seem to be a way around these contraptions.

Anyone using a resovior will set their pump to collect the water off the bottom or near the bottom of the resovior. With this said.

What we want to do is create some bubbles (Foam).
The air from the Foam will not get into our lines as we Draw the water from the bottom.

Put some Liquid soap into your water(which should lower temps in itself)...Move your return line so that is sits an inch or so above the water line. This will create foam ontop of the water.

Position an 80mm fan to blow across the foam. As the bubbles POP they should release heat into the air.

Keep in mind...Only the bubbles that contact the surface of the water will do any good. So do not add too much soap and try Not to get a whole bunch of turbulence on top of the water as it will give you too much Foam.

Give it a go..it works.

And this derived theory is based on what?

Id like to know how you came to the conclusion that this ,in fact, works.

Interesting theory.
I have to admit that I´m a bit old fashioned (and quite unexperienced in water cooling), so this tip seems a bit odd to me. I thought there should be *as little* foam as possible in the water.
Doesn´t the soap make it harder to bleed the system, just filling everyting with foam?
But, of course, if it works, it works. Have You seen any lower CPU temps with this foam trick?

The foam sits ON TOP of the water..as the fan blows on it...it evaporates more quickly. Evaporation releases the heat into the air.

Bubles won't really accelerate that though. They'll add some surface area, but not enough to make a difference. Plus the soap will slow evaporation some.

i dont know why but for some reason all i could think of while reading this was that episode of the brady bunch where bobby poured about a whole box of soap in the washer :P i can see someone putting an entire bottle of soap into the water and making a nice foamy water supply :P

I don't know who'd use an 'open' reservoir in their PC either?, it'd have to be a 'large & bulky' res to have enought surface area to make a difference, bubbles and all

If you want a bong, there are more efficient configurations.....

You need a res with a surface area of around 400cm2 (166''2) to merley mantain a close to ambient water temp, let alone get below, and this is with more then a single 8cm fan.

As far as raw performance goes the traditional shower head pvc bong is hard to beat if implemented properly, however latley we've come up with smaller and quieter variants that come close to their performance.

My own is completly fanless and is deviod of any water noise, it relys on the natural air flow in the room to mantain a temp around 2 degrees above ambient.

I remember a pic you posted with a big array of fans on top. Is the same setup so efficient while fanless?

well it get's the water to around 3-5 degrees below ambient with the fans on, and evaporates a lot more water in the process.

note it's not exactly sitting in still air while in fanless mode, I have a pedastal fan on the other side of the room running on low that points in it's general direction.
