<div class="IPBDescription">Came to me in the shower.</div>Not really human blood. But it did come to me in the shower.
I was thinking that sometime soon I'm going to have to upgrade my computer and I was considering going the water-cooling route. I decided that I would build the whole system myself, putting my engineering degree to work. I then started to think of the various systems that existed and their limitations. The obvious one: Having each component in series along a tube had the limitation that the final component in the series didn't get much cooling since the coolant was pretty hot already. I started to think parallel and then this idea struck me:

Why not model the cooling system based off the human circulatory system? My idea was to replace the lungs with a radiator and have the "aorta" channel the coolant from the heart with tubes of varying thickness depending on cooling need (wattage). The "heart" would be, at the most simple, a piston, wheel and rod arrangement. Ideally it'd more resemble a human heart somehow. The blocks that attach to the hot bits would be carefully designed, like human blood vessels, to make maximum surface area contact with minimum flow restriction. Similar care would be required in designing the heart valves.
Best case scenario: get one of those entirely synthetic artificial hearts that some Russian guy designed and have it throbbing on the top of the case. That'd be sweet.
Red colouring in the coolant, of course.

:p
Very Smart.
Wish an aussie didnt think of it first :O! <img src="style_emoticons/<#EMO_DIR#>/tounge.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tounge.gif" />
I take it the outside of the case will look like this or something?

I'm just curious as to whom is your heart coming from?

I'll also add that cooling your memory is really a waste of time. Your chipset is really more sensitive to heat and will provide better overclocking headroom than cooling your RAM will. I understand you want to design and build your own waterblocks. This is great.... but even more reason abandon the idea of watercooling your RAM and focus on the more heat sensitive points like your northbridge and PWM. Properly cooling your PWM (which will be a challenge in itself) can make the world of difference to your CPU temperatures.
I strongly suggest you get on the OCAU forums and have a good read through Extreme Cooling. It will save you covering a lot of ground other people already have.
Good luck <img src="style_emoticons/<#EMO_DIR#>/smile-fix.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile-fix.gif" />
How does fluid-cooling work anyway? Seems like it'd be much harder to cool an entire board at once.
<!--QuoteEnd--></div><!--QuoteEEnd-->
It doesn't cool the board, it just cools whatever you have it hooked up to. Usually the PSU fan and maybe an intake fan is enough to cool capacitors and whatever that aren't colled by the water.

Unless you submerge the entire computer in vegetable oil! Muahaha!
Mineral oil's a better choice, but it's a different theory if you're filling up the entire computer. By doing that you're using the oil as one giant heatsink instead of using the water as a heat transfer mechanism that is cooled by the radiator.
<!--QuoteEnd--></div><!--QuoteEEnd-->
Or you could combine the two. In theory, if you pumped oil off the top of the tank (where it would be warmer) then cooled it before inserting it into the bottom, you could keep your computer pretty cool.
That's electricity. Water will flow from high to low pressure along whatever conduit it can. The ratio of the cross-sections will determine the flow rate along each tube, given a set pressure. Thanks for the anti-bacterial tip. I hadn't considered that.
That picture was just a rough mock-up. I'm probably going to have a pipe going to the hard drives. Generally I find that the northbridge needs no cooling other than a heat sink and passive airflow about the case. No fan of its own. Perhaps since there'll be reduced general airflow I'll need to look at it specifically.
I've got a number of ideas relating to the actual heart. One was having the entire thing sealed up tight, and using a ring of magnets that pull the piston up and down. Obviously this'd need some shielding or clever design to eliminate stray field.

P.S. It's just occurred to me that making the blocks out of lead would be a good idea since it's soft and I can machine it at home. Like so:

Unfortunately it turns out that lead <a href="http://hyperphysics.phy-astr.gsu.edu/hbase/tables/thrcn.html" target="_blank">conducts heat like crap</a> (thanks kaine) and it gets soft as low as 60 degrees.
